Introduction

In an increase over prior terms, the Supreme Court of the United States issued six opinions involving patent law during its October 2016 Term. These decisions addressed issues ranging from patent exhaustion, multicomponent products, and biosimilar patents to procedural issues like venue and the statute of limitations for infringement claims. The increase in patent cases heard by the High Court coincides with an apparent increase in patent litigation generally. As observed by Judge Kathleen O'Malley of the U.S. Court of Appeals for the Federal Circuit (Federal Circuit), the court that has exclusive jurisdiction over most appeals involving patents: "While federal filings in complex civil cases in regional circuits have been down in recent years, the patent litigation business is booming. Indeed, patent filings in district courts have almost doubled from 2010—when there were 3,301 patent actions filed—to 2013, when ... there were 6,497 such cases instituted."
The increase in patent litigation may reflect a broader interest in patents generally. As Judge Timothy Dyk, also of the Federal Circuit, has written: "[P]atent law has ... moved further into the mainstream. And the importance of intellectual property to the broader American economy has continued to grow, with an estimated 84% of the S&P 500 Market Value attributable to intangible assets in 2015." Another commentator has noted that "patent law is indisputably more visible to lawyers and to the general public today than it was a decade or two ago. Stories about patent law, patent litigation, and even the Federal Circuit itself are regular fixtures of leading newspapers...." Accordingly, an understanding of patent law and the cases issued during the Supreme Court's recently concluded October 2016 Term will likely be of interest to Congress.
To this end, this report begins with an overview of patent law. It then discusses the Supreme Court's role in the development of patent law generally before examining the Court's recent decisions in detail. Finally, the report closes with a preview of developments in patent law that are on the horizon, such as the continued viability of certain administrative proceedings related to the validity of patents, which is the subject of two cases scheduled to be heard during the Court's upcoming term, as well as patent reform activity in the legislative and executive arenas.

	Overview of Patent Law

The patent law regime in the United States is grounded in the U.S. Constitution itself; article I, section 8, clause 8 of the Constitution provides: "The Congress Shall Have Power ... To promote the Progress of Science and useful Arts, by securing for limited Times to ... Inventors the exclusive Right to their respective ... Discoveries." Nonetheless, the rights associated with patents do not arise automatically. Rather, to obtain patent protection, the Patent Act of 1952 requires inventors to file a patent application with the PTO.

		Requirements for Obtaining a Patent

A patent may be obtained by "[w]hoever invents or discovers any new and useful process, machine, manufacture, or composition of matter, or any new and useful improvement thereof," subject to the requirements of the Patent Act. A valid patent bestows upon its holder a time-limited "franchise granting the right to exclude everyone from making, using or selling the patented invention without the permission of the patentee." This right to exclude is enforceable under the Patent Act, which states that anyone who "makes, uses, offers to sell, or sells any patented invention, within the United States or imports into the United States any patented invention during the term of the patent ... infringes the patent" unless authority to do so is secured from the patent holder.
The administrative process of applying for and acquiring a patent before the PTO is called "patent prosecution." Once an inventor files a patent application, a patent examiner at the PTO will evaluate whether the application meets the requirements of the Patent Act and thus merits the award of a patent. Under the Act, the application must include a written "specification." The specification must include:
a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art [ ] to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor or joint inventor of carrying out the invention.
In other words, the Patent Act requires that a specification meet: (1) the written description requirement , which is met when a specification "'reasonably conveys to those skilled in the art that the inventor had possession of the claimed subject matter as of the filing date'" of the patent; (2) the enablement requirement , under which "the specification ... must teach those skilled in the art how to make and use the full scope of the claimed invention without 'undue experimentation'"; and (3) the best mode requirement , which requires that the specification demonstrates that "the inventor possessed a best mode of practicing the claimed invention at the time of filing the patent application."
The Patent Act further requires that the specification "conclude with one or more claims particularly pointing out and distinctly claiming the subject matter which the inventor or a joint inventor regards as the invention." Patent claims define the parameters of what an inventor considers his or her invention. As the Federal Circuit has noted:
The function of claims is (a) to point out what the invention is in such a way as to distinguish it from what was previously known ... and (b) to define the scope of protection afforded by the patent. In both of those aspects, claims are not technical descriptions of the disclosed inventions but are legal documents like the descriptions of lands by metes and bounds in a deed which define the area conveyed but do not describe the land .
In addition to examining a patent application for compliance with the statute's specification requirements, the patent examiner also determines whether a patent application meets several substantive standards of the Patent Act. Namely, to be patentable, an invention must be (1) a "process, machine, manufacture, or composition of matter" that is (2) novel, (3) useful, and (4) nonobvious. A corollary to the first requirement that "specifies four independent categories of inventions or discoveries that are eligible for protection" is that there is certain subject matter that is ineligible for patent protection; three specific examples of unpatentable subject matter that the Supreme Court has articulated are "laws of nature, physical phenomena, and abstract ideas." As to novelty, the Act provides that a patent cannot be issued if "the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention." That is, the invention must be something new and different as compared to the so-called "prior art," which are the existing references that disclose the state of the art, such as publications and other patents. As to usefulness or utility, the patent application must demonstrate that the "claimed invention has a significant and presently available benefit to the public ... which is not so vague as to be meaningless." Finally, as to nonobviousness, the Act provides that "[a] patent for a claimed invention may not be obtained ... if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains." In other words, "a patent may be found invalid as obvious if 'there are a finite number of identified, predictable solutions, [and] a person of ordinary skill has good reason to pursue the known options within his or her technical grasp.'"

		Rights of Patent Holders

With some exceptions, a patent is generally granted "for a term beginning on the date on which the patent issues and ending 20 years from the date on which the application for the patent was filed." Notably, once this period expires, others may use the invention without regard to the expired patent. During the term of a patent, however, anyone who "makes, uses, offers to sell, or sells any patented invention, within the United States or imports into the United States any patented invention during the term of the patent ... infringes the patent" unless authority to do so is secured from the patent holder. Patent rights, however, are not self-enforcing; rather, patent holders must initiate enforcement measures themselves, most commonly through litigation in federal court.
Although issued patents are entitled to a presumption of validity, accused infringers may defend against infringement actions on several grounds, including: (1)  noninfringement or the "absence of liability for infringement" in light of a valid license or that the patent claims, when properly construed, do not cover the allegedly infringing acts; (2)  patent invalidity , that is, that a patent is invalid for failure to meet any of the statutory requirements discussed above; or (3)  unenforceability , or that a patent is unenforceable due to, for example, inequitable conduct in obtaining the patent.
There are several remedies available to the patent holder in light of a finding of infringement, and the Supreme Court has taken an active role in defining these remedies over the past decade. First, infringers can be enjoined from further infringement. Until 2006, the Federal Circuit followed a "'general rule that courts will issue permanent injunctions against patent infringement absent exceptional circumstances.'" In eBay Inc. v. MercExchange, L.L.C. , however, the Supreme Court clarified that courts must follow the four-factor test used in other areas of law before issuing a permanent injunction, thus heightening the requirement for injunctions in patent cases. 
Second, the Patent Act provides for damages "adequate to compensate for the infringement, but in no event less than a reasonable royalty for the use made of the invention by the infringer." The Act further gives courts the discretion to "increase the damages up to three times the amount found or assessed." In 2016, the Supreme Court clarified in Halo Electronics, Inc. v. Pulse Electronics, Inc. , that the award of such enhanced damages is "designed as a 'punitive' or 'vindictive' sanction for egregious infringement behavior," such as "willful infringement." Finally, attorney fees may be awarded to the prevailing party in "exceptional cases." In 2014, the Supreme Court clarified in Octane Fitness, LLC v. Icon Health & Fitness Inc. , that an "exceptional case" is "one that stands out from others with respect to the substantive strength of a party's litigating position (considering both the governing law and the facts of the case) or the unreasonable manner in which the case was litigated" based on the "totality of the circumstances."

		Major Patent Legislation

As discussed below, patent reform appears to be of perennial interest to Congress, particularly over the last few decades. While a comprehensive history of legislative activity in the patent area is beyond the scope of this report, there are several key pieces of legislation enacted since the passage of the Patent Act of 1952 that merit mention.
In 1984, Congress passed the Drug Price Competition and Patent Term Restoration Act, commonly known as the Hatch-Waxman Act, which amended both patent law as well as food and drug law. The Hatch-Waxman Act included provisions intended to facilitate the marketing of generic pharmaceuticals, while incentivizing brand-name firms to innovate. For example, abrogating then-prevailing case law, the Act allowed potential generic drug manufacturers to obtain marketing approval from the Food and Drug Administration (FDA) on a patented drug by relying on the safety and efficacy data of an approved drug, while the patent holder, in turn, receives a period of regulatory exclusivity. In other words, the Act allowed generic manufacturers to commence work on a generic version of an approved drug during the life of the patent if the work complies with FDA regulations. In 2009, Congress enacted a related statute called the Biologics Price Competition and Innovation Act of 2009, which established procedures for "biologics"—a category of medical preparations derived from a living organism—that are found to be "biosimilar" or interchangeable with an FDA-approved biologic. Both of these laws are discussed in more detail below.
The most recent patent reform legislation, and perhaps the one that has made the most significant changes to patent law in the modern era, is the Leahy-Smith America Invent Act (AIA), signed into law in September 2011. Among the significant changes the AIA made to the patent system is the so-called "first to file rule," under which the first inventor to file a patent application prevails when two or more persons independently develop the identical or similar invention at approximately the same time. This change brought the United States into conformity with all other patent-issuing countries, thereby arguably facilitating better cross-border cooperation in the patent arena. In addition, the AIA established assignee filing, which allows an inventor's employer or other entity to which patent rights are assigned to file patent applications, in contrast to the previous rule that the natural person or persons who developed an invention must file the patent application, even where the invention was developed in the inventor's capacity as an employee.
Perhaps most significantly, as explained in more detailed in the following section, the AIA established or modified various administrative challenges to the validity of an issued patent before the PTO, including (1) post-grant review , which allows petitioners to challenge patent validity for failure to meet any of the Patent Act's patentability requirements for a patent, such as ineligible subject matter or lack of enablement; (2) inter partes review , which replaced the former inter partes reexamination system; (3) supplemental examination , which allows patent holders to request an examination to "consider, reconsider, or correct information believed to be relevant to the patent"; and (4) a transitional program for covered business method patents , which is a temporary program for a subset of patents involving certain "covered business methods" that operate similarly to post-grant reviews, but will only be available through September 2020 under a sunset provision in the AIA. 
While there have not been substantial changes made to patent law through legislation since the enactment of the AIA, as discussed below, there remains the possibility of future changes. As well, certain cases before the federal courts have the potential to invalidate some provisions of the AIA, such as those providing for inter partes review proceedings.

		Administrative Proceedings Before the PTO

As is evident, in addition to patent prosecution, the PTO conducts other administrative review proceedings, including those provided for in the AIA. Most of these proceedings involve challenges to the validity of issued patents and may result in the revocation of a previously issued patent. Such proceedings play a central role in the country's patent system as a popular, "less expensive and quicker alternative to litigation."
A post-grant review, made available under the AIA, allows petitioners to challenge a patent's validity based on any ground of patentability, but must be filed within nine months of the date the patent was granted. After a petition for a post-grant review is filed, the patent holder has the opportunity to file a response arguing that the post-grant review should not be initiated. If such a review is initiated, however, the PTO's Patent Trial and Appeal Board (PTAB) will conduct a trial and issue a final written decision, which can be appealed to the federal courts.
Also created by the AIA, an inter partes review allows any person (other than the patent holder) to challenge a patent based on previously issued patents or printed publications (i.e., the prior art) on the basis of novelty and/or nonobviousness. Such petitions may be filed at least nine months after a patent issues or a post-grant review concludes, whichever is later. As a result, a patent may be challenged administratively on any basis of patentability within nine months of the date it was granted through a post-grant review, after which it can be challenged on novelty and nonobviousness grounds through an inter partes review for the remainder of the patent's term. Both types of proceedings involve a trial-like procedure before a three-member panel, and include the use of witnesses, limited discovery, and a hearing prior to a decision on the merits.
Finally, reexamination proceedings, which predate the enactment of AIA, allow any person, including the patent holder or the PTO Director, to cite prior art to challenge an issued patent on novelty or nonobviousness grounds. Unlike post-grant review and inter partes review proceedings, however, reexaminations effectively reopen prosecution of an issued patent and proceed on an ex parte basis (i.e., between the patent applicant and the PTO without participation by third parties). In addition, reexamination proceedings result in either (1) a certificate confirming the patentability of the patent, (2) the reissue of the patent with narrowed claims, or (3) a declaration of patent invalidity.

		Proceedings Before the Federal Courts

The Federal Circuit has exclusive, nationwide jurisdiction over the majority of patent appeals, while the Supreme Court has discretionary authority to review cases decided by the Federal Circuit. The Federal Circuit also has jurisdiction over appeals involving veterans' claims, government contracts, federal taxation, claims under the Vaccines Act, grievance claims from federal employees, appeals involving international trade matters, among others. Notably, the Federal Circuit has "no criminal jurisdiction, hear[s] few constitutional issues, and almost no cases involve state-law issues." This unique jurisdictional purview may be responsible for what one commentator has described as a view of the Federal Circuit, on the part of Supreme Court and the other circuit courts, "as inhabiting a world apart." Some even view the Federal Circuit as a "rogue" court that is frequently reversed by the Supreme Court. However, although over the last decade the reversal rate for the Federal Circuit has been above the median of the circuit courts, it has been lower than five of its twelve sister circuits. Nonetheless, "a perceived tension between the Supreme Court and [the Federal Circuit] by the bar and by the academy" appears to exist, with some commentators questioning whether "the Supreme Court understands patent law well enough to make the governing rules," and others criticizing the Federal Circuit as "having a parochial attitude or a we know best attitude toward patent law."
With respect to its patent docket, the Federal Circuit's appeals originate from three main sources: the federal district courts, the PTO, and the U.S. International Trade Commission. Since the enactment of the AIA in 2011, however, there has been "substantial growth" in appeals coming from PTO proceedings: "In 2000, cases from the [PTO] made up only 4% of [the Federal Circuit's] docket while in 2016 they were 33%. " This trend demonstrates the significance of the PTO's administrative proceedings to the country's patent system.
As noted, the Supreme Court has taken an increasing number of cases involving patent law and other areas of intellectual property over the last decade, perhaps indicating the Court's heightened interest in patent law or recognition of its increased prominence in society as a whole. Ten years ago, Judge Dyk predicted that the Supreme Court would continue its trend of hearing more cases from the Federal Circuit involving substantive patent law, a prediction that is proving to hold true. Indeed, based on annual statistics on the Supreme Court published by the Harvard Law Review , from the October 2006 Term through the October 2015 Term "the Supreme Court has taken an average of four [Federal Circuit] cases each term, representing 5.4% of the Court's merits cases. A large proportion of those cases have involved substantive patent law or related procedural issues." Because of this increase, one commentator has stated: "No longer is the Federal Circuit 'the de facto Supreme Court of patents.'"
While the High Court is playing a larger role in the development of patent law by issuing an increased number of patent law opinions, the nature and extent of the Court's influence on patent law is the subject of some debate. Indeed, while Judge Dyk has asserted that "[t]he Supreme Court's decisions have had a major impact on patent law [and] ... have involved important and foundational questions with enormous impacts on patent litigation," others contend that "the sheer quantity of patent cases decided by the Supreme Court in recent years might make it seem as if the Court is serving as a percolating force in patent law by disrupting ossified doctrine and engaging in independent analyses of what the law should be.... But the key doctrines governing novelty, nonobviousness, and disclosure have remained relatively static." Nonetheless, the increased number of Supreme Court opinions involving patent law has evinced several trends.
One trend involves cases wherein the Court addresses a legal issue that is present in federal litigation generally, but appears to have been treated differently in the patent law context. Examples include eBay Inc. v. MercExchange, L.L.C. , addressing the test for issuing injunctions; MedImmune, Inc. v. Genentech, Inc. and Medtronic, Inc. v. Mirowski Family Ventures, LLC , addressing declaratory judgments; and Gunn v. Minton , addressing subject matter jurisdiction. A second trend involves an apparent effort on the part of the Court to harmonize patent law with other areas of federal law, such as copyright. Examples include Global-Tech Appliances, Inc. v. SEB S.A. , where the Court relied on the doctrine of willful blindness from criminal law to articulate the mental state requirement for induced patent infringement; Octane Fitness, LLC v. ICON Health & Fitness, Inc. , wherein the Court relied on case law interpreting the fee-shifting provision of the Copyright Act to determine the appropriate standard for awarding attorney fees under the Patent Act; and Commil USA, LLC v. Cisco Sys., Inc. , which drew upon knowledge requirements for civil and criminal liability to determine if liability for induced infringement is possible in the absence of actual knowledge. As shall be seen, further examples of the trends are evident in some of the Court's opinions issued during its October 2016 Term, as discussed below.

	Patent Cases of the Supreme Court's October 2016 Term

		Cases Involving Procedural Issues

The Supreme Court issued two opinions involving procedural issues during its October 2016 Term that will affect when and where patent cases will be filed. Notably, in TC Heartland LLC v. Kraft Foods Group Brands LLC , the Court overruled long-standing Federal Circuit precedent with regard to venue rules in patent cases, holding "that a domestic corporation 'resides' only in its State of incorporation for purposes of the patent venue statute." And in SCA Hygiene Products Aktiebolag v. First Quality Baby Products, LLC , the Court ruled that the equitable doctrine of laches, which protects against unreasonable, prejudicial delay in commencing suit, is not available in a patent infringement action filed within the Patent Act's statute of limitations.

			TC Heartland v. Kraft Foods Group Brands

TC Heartland centered on the meaning of the patent venue statute, 28 U.S.C. § 1400(b), which provides that "[a]ny civil action for patent infringement may be brought in the judicial district where the defendant resides, or where the defendant has committed acts of infringement and has a regular and established place of business." Congress has amended the general venue statute twice, but has not amended the patent-specific statute, since the Court issued its 1957 opinion in Fourco Glass Co. v. Transmirra Products Corp. , which held that the patent-specific venue statute "is the sole and exclusive provision controlling venue in patent infringement actions, and ... is not to be supplemented by ... [the general venue statute, 28 U.S.C.] § 1391(c)." Nevertheless, after Congress amended the general venue statute in 1988 (but not the patent-specific statute), the Federal Circuit held in 1990 that this change also altered the patent-specific statute by reference.
Specifically, under the 1988 amendments, the general venue statute provided that, "[f]or purposes of venue under this chapter , a defendant that is a corporation shall be deemed to reside in any judicial district in which it is subject to personal jurisdiction at the time the action is commenced." In VE Holding Corp. v. Johnson Gas Appliance Co. , the Federal Circuit held that through this amendment of the general venue statute, Congress also changed the meaning of "resides" in the patent-specific venue statute. Accordingly, in the time since VE Holding was issued, the Federal Circuit has followed the rule that venue in patent cases is proper anywhere a defendant is subject to personal jurisdiction. 
In 2011, Congress enacted the current version of the general venue statute, again leaving the patent-specific statute unaltered. Similar to the 1988 version, the present general venue statute provides: "Except as otherwise provided by law" and "[ f ] or all venue purposes ," a corporation "shall be deemed to reside, if a defendant, in any judicial district in which such defendant is subject to the court's personal jurisdiction with respect to the civil action in question." The Federal Circuit considered this amendment in its opinion in TC Heartland , and reaffirmed its holding in VE Holding , "reasoning that the 2011 amendments provided no basis to reconsider its prior decision."
In 2014, Kraft Foods, a corporation organized under Delaware law with its principal place of business in Illinois, sued TC Heartland, a company organized under Indiana law and headquartered in Indiana, for patent infringement in the federal district court for the District of Delaware. Although TC Heartland was not registered to conduct business in Delaware, and had no meaningful presence there, it had shipped a small amount of the allegedly infringing products into Delaware. Relying on VE Holding Corp. , the district court in Delaware dismissed TC Heartland's motion to dismiss the case or transfer venue to the district court for the Southern District of Indiana, and the Federal Circuit subsequently denied TC Heartland's petition for a writ of mandamus on the same grounds.
In a unanimous opinion for the Court, Justice Clarence Thomas reversed the Federal Circuit based on Fourco . In reversing, the Supreme Court stated: "In Fourco, this Court definitively and unambiguously held that the word 'reside[nce]' in § 1400(b) has a particular meaning as applied to domestic corporations: It refers only to the State of incorporation. Congress has not amended § 1400(b) since Fourco, and neither party asks us to reconsider our holding in that case." Thus, the Court "conclude[d] that the amendments to § 1391 [(i.e., the general venue statute)] did not modify the meaning of § 1400(b) [(i.e., the patent-specific venue statute)] as interpreted by Fourco . [The Court] therefore h[e]ld that a domestic corporation 'resides' only in its State of incorporation for purposes of the patent venue statute."
The practical effects of the Federal Circuit's ruling in VE Holdings were dramatic. In fact, although there are ninety-four federal district courts in the United States, a single district court, that of the Eastern District of Texas, received almost half (44%) of all patent cases filed in 2015. By way of comparison, the District of Delaware had the second largest number of patent cases at 9%, followed by the Central and North Districts of California with 5% and 4%, respectively. In addition, one judge in the Eastern District of Texas handled two-thirds of the district's patent cases, meaning a single judge was assigned to nearly one-third of all the country's patent cases. Commentators have suggested that the popularity of the Eastern District of Texas as a venue for patent cases post- VE Holdings cannot be attributed to "geographical clustering of patent-intensive industries, as major technology hubs are located elsewhere," but is instead explained by "the patentee-friendly reputation of the district, attracting litigation through favorable procedural and administrative practices in patent cases." Perhaps unsurprisingly, calls for venue reform in patent cases came from many corners, particularly in light of the attention the issue received in national media reporting, such as stories describing "the empty Texas offices rented by patentees and the skating rink sponsored by Samsung just outside the courthouse to curry favor with local juries." The issue has also been the subject of legislative proposals, as recently as last year. The Supreme Court's decision in TC Heartland , however, arguably dissipates many of these concerns.
As to the immediate impact of the TC Heartland decision, since it was issued on May 22, 2017, patent complaints filed in July 2017 in the Eastern District of Texas decreased 43% compared to June 2017, which is a decrease of 83% compared to July 2016. And, conversely, the District Court for Delaware received the greatest number of patent complaints for two months in a row after the opinion was issued, twice as many when compared to the same time year ago. Similarly, patent filings in the District Court for Central California increased by more than a third after the opinion was issued. The long-term effects of TC Heartland , however, remain to be seen.
Of note to Congress, in addition to a potential long-term geographic redistribution of patent cases among the federal district courts, commentators have also suggested that TC Heartland may curb cases filed by non-practicing entities, better known as "patent trolls." Non-practicing entities are "patent owners who do not actually practice the invention that is the subject of the patent.... Trolls are generally considered entities that purchase patents for the purpose of generating capital by enforcing them." Of the cases filed in the Eastern District of Texas in 2015 (which as noted constituted 44% of the country's patent filings), 95% were filed by non-practicing entities. Thus, the unavailability of that venue for the many patent cases that are filed against corporations that are not incorporated in that forum may disincentivize the filing of patent cases by non-practicing entities.

			SCA Hygiene Products Aktiebolag v. First Quality Baby Products

Another opinion involving a procedural issue, but arguably with potentially fewer ramifications, is the Court's opinion in SCA Hygiene Prod uct s Aktiebolag v. First Quality Baby Prod uct s , wherein the Court addressed "the relationship between the equitable defense of laches and claims for damages that are brought within the time allowed by a statute of limitations." This was the subject of the Court's opinion three years earlier, in the context of the Copyright Act, in Petrella v. Metro-Goldwyn- Mayer, Inc. , wherein the Court concluded "in face of a statute of limitations enacted by Congress, laches cannot be invoked to bar legal relief." In SCA Hygiene , the Court held that " Petrella 's reasoning applies to a similar [statute of limitations] provision of the Patent Act," 35 U.S.C. § 286, and therefore "[l]aches cannot be interposed as a defense against damages where the infringement occurred within the period prescribed by § 286." Thus, this opinion can be viewed as an example of one in which the Court harmonizes patent law with other areas of federal law, as discussed above.
The underlying suit began in October 2003 when SCA, a manufacturer of adult incontinence products, sent a letter to First Quality alleging that the company was making and selling infringing products. In response, First Quality informed SCA that one of First Quality's patents actually antedated SCA's patent, and therefore SCA's own patent was invalid. No further communication between the companies occurred until August 2010, when SCA filed a patent infringement action again First Quality. In the intervening period, SCA had initiated a reexamination proceeding before the PTO, and obtained a certificate confirming the validity of SCA's patent in light of First Quality's patent. First Quality moved to dismiss SCA's infringement action based on laches and equitable estoppel. In an en banc opinion, the Federal Circuit held that laches can defeat an infringement claim for damages even if it was filed within the Patent Act's six-year statute of limitations. The Supreme Court reversed based on its opinion in P e trella .
Of possible interest to Congress, the Court in SCA Hygiene emphasized that:
Petrella 's holding rested on ... separation-of-powers principles.... When Congress enacts a statute of limitations, it speaks directly to the issue of timeliness and provides a rule for determining whether a claim is timely enough to permit relief. The enactment of a statute of limitations necessarily reflects a congressional decision that the timeliness of covered claims is better judged on the basis of a generally hard and fast rule rather than the sort of case-specific judicial determination that occurs when a laches defense is asserted. Therefore, applying laches within a limitations period specified by Congress would give judges a "legislation-overriding" role that is beyond the Judiciary's power. As we stressed in Petrella , "courts are not at liberty to jettison Congress' judgment on the timeliness of suit."
Accordingly, in SCA Hygiene the High Court demonstrated that its prohibition on the use of laches as an equitable defense in cases claiming damages extends beyond the copyright context of Petrella , and may extend to arguably all statute of limitations enacted by Congress. Thus, the unavailability of laches is a consideration when such statutes are drafted.
One potential practical consequence of the Court's SCA Hygiene opinion, as described in Justice Stephen Breyer's dissenting opinion and by at least one commentator, is that patent holders may now wait until close to the expiration of the six-year limitations period to file infringement cases so that damages will have the maximum amount of time to accrue. As Justice Breyer observed, in the wake of SCA Hygiene , "a patentee has considerable incentive to delay suit until the costs of switching—and accordingly the settlement value of a claim—are high. The practical consequences of such delay can be significant, as the facts of this case illustrate: First Quality invested hundreds of millions of dollars in its allegedly infringing technologies during the years that SCA waited to bring its suit." And, unlike the Patent Act, Justice Breyer points out that the Copyright Act "has express provisions that mitigate the unfairness of a copyright holder waiting for decades to bring his lawsuit." This, according to Justice Breyer, is a difference between the patent and copyright regimes that should have prevented the majority from applying Petrella in the patent law arena. The extent to which this tactic will be used in future patent litigation of course remains to be seen.

		Cases Involving Multicomponent Products

In another pair of cases heard during the Supreme Court's October 2016 Term, the Supreme Court dealt with issues related to patents on multicomponent inventions—one in the context of determining infringement and another in the context of calculating damages.

			Life Technologies v. Promega

Section 271(f)(1) of the Patent Act provides that anyone who supplies "in or from the United States all or a substantial portion of the components of a patented invention, where such components are uncombined in whole or in part, in such manner as to actively induce the combination of such components outside of the United States in a manner that would infringe the patent if such combination occurred within the United States, shall be liable as an infringer." In Life Technologies v. Promega , the Supreme Court addressed "whether the supply of a single component of a multicomponent invention is an infringing act under [this provision]." The Court held that it does not, stating "a single component does not constitute a substantial portion of the components that can give rise to liability under § 271(f)(1)."
Life Technologies involved a license for a patent on a toolkit for genetic testing. The toolkit covered by the patent contained five components, one of which was the enzyme Taq polymerase. Promega was the exclusive licensee of the patent and sublicensed it to Life Technologies, a manufacturer of genetic testing kits. Life Technologies manufactured all components of its toolkits in the United Kingdom, except for the Taq polymerase, which it made in the United States. The company then shipped the Taq polymerase to its United Kingdom facility, where it was combined with the other four components of the kit. Four years into this agreement, Promega sued Life Technologies on the grounds that it infringed the patent by selling the toolkits outside of the allowable fields of use in the license, which was limited to clinical and research markets. Because Life Technologies supplied the Taq polymerase from the United States to its United Kingdom manufacturing facilities, Promega alleged liability under § 271(f)(1).
On appeal to the Federal Circuit, the court held that "there are circumstances in which a party may be liable under § 271(f)(1) for supplying or causing to be supplied a single component for combination outside the United States." Based on the facts of this case, the court concluded "that substantial evidence supports the jury's verdict that LifeTech is liable for infringement under § 271(f)(1) for shipping the Taq polymerase component of its accused genetic testing kits to its United Kingdom facility." The Supreme Court disagreed.
The High Court started with what it considered a "threshold determination" as to "whether § 271(f)(2)'s requirement of 'a substantial portion' of the components of a patented invention refers to a quantitative or qualitative measurement." Based on the text of the statute, the Court concluded that "[t]he context in which 'substantial' appears in the statute ... points to a quantitative meaning here." Next, the Court addressed "whether, as a matter of law, a single component can ever constitute a 'substantial portion' so as to trigger liability under § 271(f)(1)," and concluded "[t]he answer is no." Therefore, the Court held "that § 271(f)(1) does not cover the supply of a single component of a multicomponent invention."
This case may appear to be limited to its facts, but arguably has consequences in a marketplace characterized by global supply chains, as well as for the presumption against extraterritoriality, under which this country's patent laws are said to only have force on U.S. soil. While the opinion does not discuss the presumption, it begins with the assertion that "[t]his case concerns the intersection of international supply chains and federal patent law." One observer has noted that, despite not providing guidance on the presumption against extraterritoriality, to some extent the opinion delineates aspects of "the risk that some parts of the [global supply] chain could be exposed to patent infringement liability." As another commentator put it, the Court's holding "that a single component never qualifies as a substantial portion of the components—tends to curb the extraterritorial effects of Section 271(f), and that result is sensible given that the baseline rule of U.S. patent law is still a principle of territoriality." Thus, this case is of particular interest to those who manufacture multicomponent products, such as smartphones—the subject of the Court's other case involving multicomponent products this term—outside of the United States.

			Samsung Electronics v. Apple

In a second case involving multicomponent products—this time Apple's iPhone—the Supreme Court was again called upon to interpret the Patent Act, this time to determine:
whether, in the case of a multicomponent product, the relevant "article of manufacture" must always be the end product sold to the consumer or whether it can also be a component of that product. Under the former interpretation, a patent holder will always be entitled to the infringer's total profit from the end product. Under the latter interpretation, a patent holder will sometimes be entitled to the infringer's total profit from a component of the end product.
Under § 289 of the Patent Act, anyone who manufactures or sells "any article of manufacture to which [a patented] design or colorable imitation has been applied shall be liable to the owner to the extent of his total profit." In Samsung Electronics v. Apple , the Federal Circuit identified Samsung's entire smartphone as the "article of manufacture" for purposes of calculating damages under § 289 because "[t]he innards of Samsung's smartphones were not sold separately from their shells as distinct articles of manufacture to ordinary purchasers." The Supreme Court disagreed.
The underlying infringement case involved three Apple design patents for its iPhone: "the D618,677 patent, covering a black rectangular front face with rounded corners, the D593,087 patent, covering a rectangular front face with rounded corners and a raised rim, and the D604,305 patent, covering a grid of 16 colorful icons on a black screen." After Apple released the first generation of its iPhone in 2007, Samsung released a series of smartphones that resembled Apple's iPhone. A jury found Samsung's smartphones infringed the design patents and awarded Apple $399 million in damages, Samsung's entire profit from sales of the infringing smartphones, which the Federal Circuit upheld.
In reversing, the Supreme Court grounded its decision on its interpretation of the statutory term "article of manufacture," which it found to be "broad enough to encompass both a product sold to a consumer as well as a component of that product. A component of a product, no less than the product itself, is a thing made by hand or machine." In doing so, the Court found the Federal Circuit's reading of "'article of manufacture' in § 289 to cover only an end product sold to a consumer gives too narrow a meaning to the phrase," but the Court remanded to the Federal Circuit to determine the relevant article of manufacture for the each of the design patents found to be infringed in this case. Resolution of that issue is ongoing.
While this case was limited to the issue of damages in the context of Apple's design patents, it is but one of many patent cases between Apple and Samsung related to their smartphones. In fact, on June 26, 2017, the Supreme Court invited the Solicitor General to file a brief "expressing the views of the United States" on Samsung's petition for certiorari to review the Federal Circuit's decision in another Samsung Electronics v. Apple case. That case involves three Apple patents: one patent covering the iPhone's autocorrect function, one covering the iPhone's "slide-to-unlock" feature, and one covering the iPhone's "quick links" feature, which initiates certain actions when users click on certain data (e.g., starting an email message when a user clicks on an email address). In an en banc opinion, the Federal Circuit upheld a jury verdict that found Samsung infringed all three patents, thereby overturning a Federal Circuit panel decision that found the autocorrect and slide-to-unlock patents were invalid as obvious and the quick links patent was not infringed. Should the Court grant certiorari in this case, it could have implications for substantive patent law, in particular the patentability requirement of nonobviousness.

		Cases with Implications for the Health Care Industry

A final pair of patent cases decided by the Supreme Court during its October 2016 Term may have major implications for the pharmaceutical industry. According to the U.S. Department of Commerce, in 2015, pharmaceutical sales in the United States grossed $333 billion, comprising 1.9% of gross domestic product. While the U.S. pharmaceutical industry stands as one of the largest sectors of the economy, it is also among the most research and development (R&D) intensive—the "industry generally allocates 15–20 percent of revenues to R&D activities and invests over $50 billion on R&D annually." Furthermore, with only about a 10% chance of succeeding, moving an investigative drug through the costly and time-consuming Food and Drug Administration (FDA) approval process means the stakes for research-based pharmaceutical companies are high, necessitating a legal regime that encourages such companies to make the necessary investments to create new drug products. At the same time, the high costs of R&D have, in turn, led to correspondingly high costs to consumers for pharmaceutical products, requiring laws that encourage competition among drug manufacturers to drive down drug costs. These conflicting interests—the interest in innovation and the interest in competition—lie at the heart of the law regulating pharmaceuticals.

			The Legal Landscape for Health Care Innovators

It is in this context that the Supreme Court issued two opinions this term at the intersection of patent and food and drug law, both of which raise issues of interest to Congress, as the Court gauges the proper balance Congress sought between innovation and competition in federal drug law. This section of the report will begin with a brief background on the legal landscape for health innovators, particularly, the patent regime and regulatory framework for medical products in the United States. Next, this section will cover the Supreme Court's decision in Impression Products v. Lexmark , a case centered on the patent exhaustion doctrine with implications across industries, particularly the pharmaceutical and medical device industries. Last, this section will cover the Supreme Court's decision in Sandoz v. Amgen , a case in which the Court interpreted certain statutory provisions in the Biologics Price Competition and Innovation Act (BPCIA), with the potential to affect the speed at which competition emerges for biologic products. 
As noted, the U.S. patent law regime working in tandem with other statutorily prescribed protections—in particular, those provided for under food and drug law—has established a legal environment that aims to be hospitable to health innovation. Of note, the Hatch-Waxman Act, which was signed into law in 1984 with the congressional intent of striking a balance between fostering innovation and advancing consumer interests, encourages the manufacture of generic drug products by establishing the abbreviated regulatory scheme for approving generic drugs and providing a framework for resolving consequent patent disputes. Under federal law, in order for a new (i.e., "pioneer" or "brand name") drug to be marketed, a manufacturer must first obtain FDA approval of a new drug application (NDA). As a prerequisite to submitting an NDA, the manufacturer must conduct, or arrange to conduct, clinical studies designed to show that the drug is safe and effective for its intended use in accordance with section 505(d) of the Food, Drug, and Cosmetic Act (FD&C Act). Conversely, Hatch-Waxman's abbreviated pathway to approval for generic drugs created a new type of marketing application, the abbreviated new drug application (ANDA), which does not require clinical testing, but instead requires a third party or generic manufacturer to show that its drug formulation is a therapeutically equivalent copy of the brand name drug being marketed.
Significantly, Hatch-Waxman also amends the FD&C Act to provide for periods of time in which a new drug is the exclusive drug on the market. These periods of market exclusivity provided for under food and drug law are sometimes referred to as a type of "regulatory exclusivity," which are in addition to and distinct from patent term exclusivity. That is to say, market exclusivity under food and drug law may still be in effect even if the drug is not under patent protection. More specifically, the Hatch-Waxman Act provides a five-year period of market exclusivity for new molecular entities and three years of market exclusivity for a new use or new formulation of previously approved drug products. To encourage the production of generic drugs, the Hatch-Waxman Act also created a 180-day exclusivity period for the first approved generic version of a brand-name drug product. Congress also provided additional market exclusivity under the Patent Act. In response to criticisms that the lengthy FDA approval process eroded the benefit of patent term market exclusivity, the Hatch-Waxman Act provided for "patent term restoration," allotting additional time to the patent term of a pioneer drug in order to compensate the patent holder for the time lost during clinical trials and the FDA review process. 
More recently, in 2010, as part of the Patient Protection and Affordable Care Act, Congress enacted the BPCIA for the stated purpose of "balancing innovation and consumer interests." While there are important differences between the two statutes, like Hatch-Waxman, the BPCIA sought to achieve this goal through changes to food and drug as well as patent law. With respect to food and drug law, the BPCIA establishes an abbreviated pathway for regulatory approval of "follow-on biologics" or "biosimilars"—lower-cost versions of biologics. A "biological product" or "biologic" is a medical product made from natural resources (human, animal, microorganism) used in the prevention, treatment, or cure of disease. The traditional route for FDA approval of a biological product for commercial marketing is through a biologics license. In order to obtain a license to market a biologic, a sponsor must complete a biologics licensing application (BLA), wherein the sponsor provides clinical data—the results of a costly multi-phase clinical trial process—demonstrating that the product is "safe, pure, and potent." Under the BPCIA's abbreviated pathway, a biosimilar applicant filing an abbreviated biologics license application (aBLA) must, in order to receive approval, submit information sufficient to show that a product is "biosimilar" to or "interchangeable" with a previously approved biologic (i.e., "reference product") and rely upon "publicly-available information regarding [FDA's] previous determination that the reference product is 'safe, pure, and potent.'" In balancing innovation with competition, the BPCIA also provides for a 4-year and 12-year exclusivity period for a reference product wherein (1) an aBLA may not be submitted prior to the date that is 4 years after the date on which the reference product was first licensed and (2) approval of an aBLA may not be made effective until the date that is 12 years after the date on which the reference product was first licensed. With respect to patent law, the BPCIA creates a process, discussed in greater detail below, that endeavors to speed the litigation of patents, while protecting the innovator's patent rights.

			Impression Products v. Lexmark

On May 30, 2017, in a nearly unanimous decision, the Supreme Court reversed the Federal Circuit in a case respecting the doctrines of domestic and international patent exhaustion, holding in Impression Products v. Lexmark International that "a patentee's decision to sell a product exhausts all of its patent rights in that item, regardless of any restrictions the patentee purports to impose or the location of the sale." Although the case arose out of a dispute over printer cartridges, the question at the heart of the dispute—whether restrictions placed on the sale of a patented product are enforceable under patent law—has significant implications across a number of industries, particularly the pharmaceutical and medical device industries.
To understand the Impression Products ruling, it is important to note several broad principles of patent law. In addition to providing a private right of action against anyone who, without authority from the patent holder, "makes, uses, offers to sell, or sells any patented invention, within the United States or imports into the United States any patented invention during the term of the patent," Section 1498 of Title 28 provides an express statutory means by which a patent holder can recover compensation for infringement of a patent by the federal government. Specifically, the statute provides that whenever a patent "is used or manufactured by or for the United States without license of the owner," the patent holder may bring an action in United States Court of Federal Claims to recover "his reasonable and entire compensation for such use and manufacture." Patent holders also have certain ancillary rights, such as the right to license their patented products and the right to sell or license their patented products with restrictions, including via so-called "Single Use" provisions, through contractual agreements.
There is, however, a key limitation on the rights of patent holders called the doctrine of patent exhaustion. The common law "exhaustion doctrine" (also known as the "first sale doctrine") stands for the principle that once an authorized sale of a patented article occurs, the patent holder's exclusive rights to control the use and sale of that article under patent law are said to be "exhausted," freeing the purchaser to use or resell the article without restraint. The basis for this principle, as articulated by the Supreme Court, is that "[t]he purpose of the patent law is fulfilled with respect to any particular article when the patentee has received his reward ... by the sale of the article"; once that "purpose is realized the patent law affords no basis for restraining the use and enjoyment of the thing sold." It is important to note, however, that the patent exhaustion doctrine applies only to the particular item sold and does not otherwise free a buyer to replicate or reproduce the patented item into a new product. Prior to the Supreme Court's ruling in Impression Products , the Federal Circuit's prevailing precedent allowed patent holders to place post-sale use and resale restrictions on domestic sales without implicating the doctrine of patent exhaustion and exempted sales abroad from the first sale doctrine entirely. In other words, patent holders maintained the ability to (1) sue for infringement if restrictions placed on domestic sales were not observed and (2) recoup more than a single reward for the sale of a patented item if the first sale was made abroad. Impression Products explicitly overturned the Federal Circuit's precedent with respect to both issues, changing the legal landscape for patent holders.
The controversy at issue in Impression Products stems from certain practices of companies known as "remanufacturers" that violated restrictions Lexmark had placed on the sales of its patented printer cartridges. Consumers had two options when purchasing toner cartridges from Lexmark—they could either buy the cartridge at full price with no restrictions, or they could buy the cartridge at a discount through Lexmark's "Return Program." In order to receive the discounted price through the Return Program, however, customers had to sign a contract agreeing to use the cartridge only once and then return it to Lexmark. Despite these restrictions, remanufacturers would acquire the Lexmark cartridges, including those initially sold through the Return Program, refill them with toner, and sell them at a discounted rate. Remanufacturers also acquired Lexmark cartridges sold overseas, reimported them into the United States, and refilled and sold them along with the Return Program cartridges. 
Lexmark sued a number of these remanufacturers, including Impression Products, for patent infringement with respect to two groups of cartridges: (1) those cartridges sold as part of the Return Program within the United States on the theory that the prohibited reuse and resale of these products infringed Lexmark's patents; and (2) all cartridges sold abroad that Impression Products imported into the United States on the theory that, because Lexmark never authorized the import of its cartridges, Impression Products infringed its patents by doing so. Impression Products moved to dismiss on the grounds that Lexmark's sales, both in the United States and abroad, exhausted all patent rights and freed Impression Products to refurbish, resell, and import products acquired overseas. The district court granted the motion with respect to the domestic Return Program sales, but denied the motion as to the cartridges sold abroad based on Federal Circuit precedent. On appeal, the Federal Circuit ruled in favor of Lexmark with respect to both groups of cartridges. 
The Supreme Court's decision to reverse the Federal Circuit with respect to both domestic and international patent exhaustion appears to rest on the underlying principle that, "when an item passes into commerce, it should not be shaded by a legal cloud on title as it moves through the marketplace." Referring to its 2013 ruling in Kirtsaeng v. John Wiley & Sons , a case involving copyright law, the Court noted that "we have explained in the context of copyright law that exhaustion has an 'impeccable historic pedigree,' tracing its lineage back to the 'common law's refusal to permit restraints on the alienation of chattels.'" In this manner, I mpression Pr oducts can be viewed as an example of one in which the Court harmonizes an aspect of patent law with other areas of federal law, as discussed above.
The Supreme Court reasoned that the Federal Circuit reached a different result because it "got off on the wrong foot." The Court described the Federal Circuit's view that "exhaustion must be understood as an interpretation of the patent infringement statute." The Federal Circuit, according to the Court, viewed exhaustion as not requiring a patentee to hand over the "full bundle of rights" every time it makes a sale, but rather allows a patentee to "withhold a stick from the bundle, perhaps by restricting the purchaser's resale rights." The Court countered:
The misstep in [the Federal Circuit's] logic is that that the exhaustion doctrine is not a presumption about the authority that comes along with a sale; it is instead a limit on "the scope of the patentee's rights." The right to use, sell, or import an item exists independently of the Patent Act. What a patent adds—and grants exclusively to the patentee—is a limited right to prevent others from engaging in those practices. Exhaustion extinguishes that exclusionary power. As a result, the sale transfers the right to use, sell, or import because those are rights that come along with ownership, and the buyer is free and clear of an infringement lawsuit because there is no exclusionary right left to enforce. 
With respect to international patent exhaustion, commentators had, prior to this ruling, questioned Kirtsaeng 's application to international patent exhaustion, noting distinctions between copyright and patent law. Namely, unlike the first-sale doctrine in copyright law, commentators noted that patent exhaustion has not been codified, and patent rights have a territorial requirement restricting their reach to the United States. Likewise, in refusing to extend patent exhaustion extraterritorially, the Federal Circuit also emphasized distinctions between copyright and patent law, in particular the difference in breadth of scope. Specifically, while patent law affords the right to exclude others from use, copyright law does not. The Supreme Court, however, took another position. Noting that "patent exhaustion, too, has its roots in the antipathy toward restraints on alienation," the Court stated that "applying patent exhaustion to foreign sales is just as straightforward" as applying the first sale doctrine to foreign sales of copyrighted works. To this end, the Court emphasized that "nothing in the text or history of the Patent Act shows that Congress intended to confine that borderless common law principle to domestic sales. In fact, Congress has not altered patent exhaustion at all; it remains an unwritten limit on the scope of the patentee's monopoly."
While the Supreme Court's decision in Impression Products suggests that patent law may not be used as a mechanism for enforcing restrictions on the sale of patented items, the Court clarified that such restrictions may remain enforceable under contract law:
If there were any lingering doubt that patent exhaustion applies even when a sale is subject to an express, otherwise lawful restriction, our recent decision in Quanta Computer, Inc. v. LG Electronics, Inc. , settled the matter ... without so much as mentioning the lawfulness of the contract, we held that the patentee could not bring an infringement suit because the "authorized sale ... took its products outside the scope of the patent monopoly." Turning to the case at hand ... whatever rights Lexmark retained are a matter of the contracts with its purchasers, not the patent law. 
Moreover, in a passage that may be of particular importance for patentees that often license others to make and sell their patented products under certain conditions, the Court explained how a license of a patented product may implicate the exhaustion doctrine. The Court noted:
A patentee can impose restrictions on licensees because a license does not implicate the same concerns about restraints on alienation of sale ... a license is not about passing title to product, it is about changing the contours of the patentee's monopoly: The patentee agrees not to exclude a licensee from making or selling the patented invention, expanding the club of authorized producers and sellers. Because the patentee is exchanging rights, not goods, it is free to relinquish only a portion of its bundle of patent protections.
At the same time, the Court emphasized that the ability to place restrictions on licenses did not provide a mechanism for circumventing patent exhaustion. The Court explained that "so long as a licensee complies with the license when selling an item, the patentee has, in effect, authorized the sale," thereby exhausting the patent. The Court also reiterated that, in the event the purchaser did not comply with the restrictions, "the only recourse for the licensee is through contract law, just as if the patentee itself sold the item with a restriction."
Contract law, however, offers significantly less protection for patent holders, as it reaches only as far as the parties in privity with the original contract. That is to say, once the patented item moves beyond the initial transaction, any restrictions made under the original contract will likely not be enforceable against new purchasers downstream. Contract law also provides less protection compared to patent law in terms of damages. As noted, the Patent Act provides for damages "adequate to compensate for the infringement," and courts are granted the discretion to grant enhanced (i.e., treble) damages. By contrast, under contract law damages are more limited—the injured party may recover damages to cover losses incurred by the breach, but treble damages are unavailable. With patent infringement no longer an available mechanism for enforcing post-sale restrictions, it is likely that many existing contracts will need to be renegotiated and that patent holders will be increasingly scrupulous in entering into future contracts, particularly with foreign parties.
Prior to the Supreme Court's decision in Impression Products , Federal Circuit precedent regarding patent exhaustion provided significant protections for patent holders by allowing them to enforce post-sale restrictions through patent infringement actions and rejecting international patent exhaustion. This legal climate, along with an increasingly global market for medical products, provided fertile ground for what is now, as commentators have noted, an entrenched business practice—the heavy use of restrictions on the domestic and international sales of patented products—within the pharmaceutical and medical device industries. Thus, as reflected in the amici briefs filed prior to the Supreme Court's Impression Products ruling, the Court's conclusion that "patent exhaustion is uniform and automatic" may have significant implications for pharmaceutical and medical device companies. 
Pharmaceutical companies have argued that changes to the legal landscape that limit patent rights would stifle innovation, ultimately hurting the public health. More particularly, the industry has long argued that patent and other regulatory exclusivities, like those provided for under the FD&C Act, are a means of recouping investments in research and development. The Supreme Court's ruling with respect to international patent exhaustion, in particular, has potentially significant implications for this industry. It is no secret that drugs are sold at different prices in different countries for a number of reasons—including that drug prices in some markets are set not by the free market, but by the foreign government; patent rights are weaker under some foreign regimes, driving down prices; and, given disparities in global wealth, some foreign markets cannot support drugs at a revenue-generating cost. As such, there is concern among industry representatives that Impression Products ' extension of patent exhaustion to foreign sales could expand grey market sales—that is, products bought and sold outside the manufacturer's authorized trading channels—of medicines originally sold in foreign markets at lower prices. According to this view, an expansion of grey market sales may, in turn, upset the balance between innovation and patient access that Congress intended to strike through statutory and regulatory mechanisms. As examples of these mechanisms, U.S. patent law provides for U.S. market exclusivity and protection from infringement, while additional regulatory exclusivities for various categories of innovative medical products are provided for under laws implemented by FDA. In addition, FDA is authorized to enforce restrictions on the importation of medical products. In the views of at least one amicus brief, the expansion of grey market sales could result in limiting patient access to medications by limiting the incentive for innovation. 
That said, given current regulatory restrictions on the importation of medical products, the law provides pharmaceutical companies with more protection than most other manufacturers with respect to the reimportation of goods sold abroad. Specifically, FD&C Act section 801(d)(1) prohibits anyone other than the manufacturer from reimporting drugs manufactured in the United States and sold abroad. Relying on this provision, one consumer advocacy group has argued that the statute "effectively prevents large-scale parallel importation of drugs originating in the United States and thus renders the impacts predicted by [industry] unlikely." 
Economic consequences may not be the only issues raised by the Supreme Court's decision scaling back a patentee's ability to enforce post-sale restrictions through patent infringement actions. In addition to economic concerns, the medical device industry argues that compromising the enforcement of restrictions on single-use devices (SUDs), which range in sophistication from compression sleeves to cardiac catheters, may pose public health risks. SUDs, which emerged in response to heightened awareness about the transmission of infectious diseases, are manufactured with the expectation that they will be discarded after one single use in one single patient. Because SUDs are not designed or constructed to be cleaned for subsequent use, some are made of materials that are unable to withstand necessary resterilization procedures.
As background, medical devices that are more complex and higher risk are typically required to obtain FDA approval prior to marketing through an application for premarket approval (PMA), which similar to an NDA, requires clinical testing to show a "reasonable assurance of safety and effectiveness" to market a device. Some less complex and lower-risk devices are eligible to instead obtain clearance for marketing through a 510(k) submission if the product is shown to be "substantially equivalent" to a predicate product (i.e., a device already on the market). FDA regulates the common cost-saving mechanism of reprocessing—the collection of discarded medical devices for cleaning, repair, and resterilization in preparation for resale—by requiring that manufacturers of reusable devices test and supply instructions for safe reprocessing and that reprocessors of SUDs demonstrate "substantial equivalence" in terms of safety and efficacy to the original manufactured product. Given that reprocessing is regulated by FDA, one may question whether post-sale restrictions are necessary to ensure safety with regard to SUDs. However, FDA itself has stated that "[r]educing the risk of exposure to improperly reprocessed medical devices is a shared responsibility among various stakeholders ... [including] manufacturers.... " Because SUDs are intended for use only once and may not—at least in some instances—be safely refurbished, manufacturers of SUDs, unlike manufacturers of reusable medical devices, are not, however, required to provide reprocessing instructions. Thus, the Medical Device Association argued in its amicus brief in Impression Products that "if all post-sale restrictions are ineffective, medical device manufacturers will be unable to ensure compliance with the guidelines for safely reprocessing reusable devices." On the other hand, it seems unlikely that all single-use restrictions would be rendered entirely ineffective by the Supreme Court's decision on patent exhaustion, as FDA still requires reprocessors to demonstrate the safety and efficacy of a refurbished SUD. Furthermore, other laws, such as state tort law or consumer protection laws, could (subject to federal preemption limits) serve as a disincentive for a reprocessor's failure to heed a manufacturer's single-use restriction where reuse risks public safety. 
Finally, while Impression Products held that post-sale restrictions are not enforceable under patent law, it also clarified that contract law remains an appropriate vehicle for remedying such violations. As previously discussed, contract remedies extend only to parties in privity with the agreement, and with respect to concerns raised by the pharmaceutical industry, contract law cannot reach downstream sales where grey market transactions are likely to occur. Likewise, because many reprocessors are independent of the hospitals and health care facilities to which the devices were originally sold, there could be situations in which patent owners are without the requisite privity to base a breach of contract claim for violating post-sale restrictions on SUDs. While it remains to be seen how significant the Supreme Court's reversal of the Federal Circuit's position on patent exhaustion will be on the pharmaceutical and medical device industries, the myriad questions raised by the Impression Products decision implicate the recurrent theme of balancing innovation and competition and thus may be of interest to Congress and the subject of future legislative debate. 

			Sandoz v. Amgen

Another Supreme Court opinion issued this term with significant implications for consumers and pharmaceutical companies is Sandoz v. Amgen , issued on June 12, 2017. This case will potentially affect the speed at which competition emerges for many pharmaceutical products. Specifically, the Supreme Court considered opposing views on how to interpret key provisions in the BPCIA. 
As noted above, in 2010, as part of the Patient Protection and Affordable Care Act, Congress enacted the BPCIA for the stated purpose of "balancing innovation and consumer interests" with the establishment of an abbreviated pathway for regulatory approval of biological products that are "highly similar" to or "interchangeable" with a previously approved FDA-licensed reference product ("reference product"). As part of this new abbreviated regulatory pathway for so-called "biosimilars" and particularly relevant to Sandoz , the BPCIA sets forth a complex patent-dispute resolution regime wherein the reference product owner can protect against potential infringements of any patents of products that are the subject of an aBLA. Thus, rather than waiting until commercial marketing to resolve disputes, the BPCIA facilitates litigation during the period preceding FDA approval. In doing so, the BPCIA "enables the parties to bring infringement actions at certain points in the application process, even if the applicant has not yet committed an act that would traditionally constitute patent infringement ... [the BPCIA] provides that the mere submission of a biosimilar application constitutes an act of infringement." The Supreme Court has referred to this type of "preapproval infringement" as "artificial infringement." 
More specifically, by amending section 262 of the Public Health Service Act, the BPCIA establishes an elaborate process for patent dispute resolution, sometimes referred to as the "patent dance." The "dance" generally involves an applicant and reference product sponsor (i.e., "the sponsor") participating in a series of informational exchanges regarding potential disputes over patent validity and infringement prior to marketing of the biosimilar. 
The Disclosure Requirement : Of particular relevance to Sandoz , the initial requirement under the BPCIA's disclosure and negotiation procedures is that the applicant "shall" grant the reference product sponsor confidential access to its aBLA application and the manufacturing information regarding the biosimilar product no later than 20 days after FDA accepts the application for review. From this disclosure, the exchange continues: pursuant to section 262( l )(3), within 60 days of disclosure, the sponsor "shall provide" to the applicant "a list of patents" for which it believes it could assert an infringement claim if a person without a license made, used, offered to sell, sold, or imported "the biological product that is the subject of the [biosimilar] application." At this time the sponsor also identifies any patents on the list that it would be willing to license. In turn, within 60 days of receiving the sponsor's list, the applicant may provide the sponsor with a list of patents that it believes are relevant, but were omitted from the sponsor's list. Next, the applicant "shall provide" to the sponsor the reasons why it could not be held liable for infringing those patents, for example because the patents are invalid, unenforceable, or not infringed. The applicant must also, if applicable, respond to the sponsor's offer to license particular patents. The sponsor then "shall provide" within 60 days responses to the applicant's arguments concerning infringement, enforcement, and validity, as to each relevant patent.
The Notice Requirement : In another relevant provision of the BPCIA, the law provides that the applicant "shall" give notice of commercial marketing to the reference product sponsor at least 180 days prior to commercial marketing. This notice provides the reference product sponsor a period of time to seek a preliminary injunction to enjoin infringing acts. Furthermore, either party may sue for declaratory relief, but the parties are barred from doing so prior to the applicant's notice of commercial marketing. 
Two-Phased Litigation : The Supreme Court's decision in Sandoz v. Amgen describes these mechanics as "channel[ing] the parties into two phases of patent litigation": (1) upon disclosure of the application and manufacturing information, the parties collaborate to identify patents for immediate litigation; and (2) upon notice of commercial marketing, the parties may litigate patents that were included on the section 262( l )(3) lists, but not litigated in the first phase. Thus, if the parties comply with the "patent dance," they will have the opportunity to litigate any relevant patents prior to commercial marketing.
Remedial Provisions : In order to encourage the parties to comply, the BPCIA also includes consequences for failing to do so. Two of these remedial provisions were of particular relevance in Sandoz . First, if the applicant fails to comply with the disclosure requirement, which effectively commences the two-phase litigation process, then the sponsor, but not the applicant, may immediately bring a declaratory action for infringement. Similarly, if the applicant fulfills the disclosure requirement, but fails to comply with the subsequent steps in the information exchange process, the applicant, but not the sponsor, may bring a declaratory judgment action with respect to any patent included on the sponsor's section 262( l )(3) list. In both instances, the BPCIA facilitates these actions by making it an artificial act of infringement to submit a biosimilar application with respect to any patent that could have been included on the section 262( l )(3) list.
The impetus behind the Sandoz litigation was Sandoz's first FDA approval under the BPCIA's new regulatory pathway for its product "Zarxio," a biosimilar for the FDA-approved anti-infective biologic filgrastim, and the first biosimilar approved under the BPCIA. Amgen, the company that has produced and marketed filgrastim under the brand name "Neupogen" since 1991, filed suit in the Northern District of California for patent infringement under 42 U.S.C. § 262( l )(9)(c). Amgen also sought an injunction in an effort to forestall market entry of Zarxio with claims grounded in two alleged violations of the BPCIA—Amgen claimed that Sandoz's failure to comply with the disclosure and negotiation procedures established by the BPCIA and its interpretation of a 180-day notice requirement both comprised actionable unlawful business practices under California law. 
With regard to participation in the BPCIA's disclosure and negotiation procedures, both the district court and the Federal Circuit held that those procedures—despite the use of the word "shall" in the statute—were not a mandate on the applicant. Rather, the lower courts viewed the disclosure and negotiation procedures as an option that confers certain benefits, largely in the form of reduced patent infringement litigation risks, in exchange for expediency in getting the product to market. Furthermore, the Federal Circuit held that an injunction was unavailable as a remedy under federal law because "42 U.S.C. section 262( l )(9)(C) and 35 U.S.C. 271(e) expressly provide the only remedies" for violating the disclosure requirement, with neither authorizing a court to compel compliance. 
While the district court held that the 180-day notice provision should be interpreted to allow the applicant to give notice to the reference product sponsor prior to FDA approval of the aBLA, the Federal Circuit vacated that holding in a split decision, maintaining that in order for notice to be effective, it must be given after the biosimilar is licensed by FDA. The Federal Circuit's interpretation of the notice requirement would have functionally provided the reference product sponsor with an additional six months of market exclusivity because the applicant could only begin to sell the biosimilar product 180 days after the FDA ended the sponsor's exclusive right to sell the biologic. Notably, the Federal Circuit seemed to suggest that the 180-day notice requirement is mandatory only if the applicant chooses to forgo the patent dance, stating that "where, as here, a[n] ... applicant completely fails to provide its aBLA and the required manufacturing information to the [reference product sponsor] by the statutory deadline, the [notice] requirement ... is mandatory." In other words, the Federal Circuit's interpretation of the "shall" language with regard to the 180-day notice provision seemed to transform a requirement into something more optional.
The Supreme Court addressed two questions arising from the dispute: (1) whether the requirement that an applicant provide its application and manufacturing information to the manufacturer of the biologic is enforceable by injunction and (2) whether the applicant must give notice to the manufacturer after, rather than before, obtaining a license from the FDA for its biosimilar.
With respect to the first question, the Supreme Court explained that Sandoz's failure to disclose its application and manufacturing information did not amount to an act of "artificial infringement" remediable by injunctive relief under the BPCIA. The Court explained that the Federal Circuit erred in its apparent conclusion that noncompliance with section 262( l )(2)(A) (i.e., the disclosure requirement) is an "element of the artificial act of infringement." Specifically, the Court noted that the Federal Circuit based its interpretation on the language in section 271(e)(2)(C)(ii), which states that "[i]t shall be an act of infringement to submit[,] if the applicant for the application fails to provide the application and information [to the reference product sponsor]." Rather, the Court held that such language "merely assists in identifying which patents will be the subject of an artificial infringement suit. It does not define the act of artificial infringement itself." The Court reached this conclusion based on the structure of 271(e), which defines artificial infringement in two separate clauses—once within the context of the list exchange process and once when an applicant fails to disclose its manufacturing information. The Court concluded that in both instances it is the act of submitting the application, rather than a failure to disclose information, that constituted the act of artificial infringement for which a remedy is provided under section 271(e)(4). Instead, the Court held that a separate provision under section 262 of the BPCIA provides a remedy for an applicant's failure to turn over its application and manufacturing information—"§262( l )(9)(C) authorizes the sponsor, but not the applicant, to bring an immediate declaratory judgement action" for artificial infringement as defined in section 271(e)(2)(C)(ii). The Court also noted, "§262( l )(9)(C) excludes all other federal remedies, including injunctive relief. Where, as here, 'a statute expressly provides a remedy, courts must be especially reluctant to provide additional remedies.'" While concluding that an injunction was unavailable under federal law as a means of enforcing the disclosure requirement, the Court remanded the decision to the Federal Circuit to determine whether an injunction is available under California law. 
With respect to the second question presented, the Court reasoned that the plain language of the statute, which requires a biosimilar applicant to provide notice to the reference product sponsor "not later than 180 days before" the date of first commercial marketing of the biosimilar product, does not require the notice to occur after FDA licenses the product. The Court explained:
The applicant must give "notice" at least 180 days "before the date of commercial marketing." "[C]ommercial marketing," in turn, must be "of the biological product licensed under subsection (k)." Because this latter phrase modifies "commercial marketing" rather than "notice," "commercial marketing" is the point in time by which the biosimilar must be "licensed." The statute's use of the word "licensed" merely reflects the fact that, on the "date of first commercial marketing," the product must be "licensed." Accordingly, the applicant may provide notice either before or after receiving FDA approval.
In support of this interpretation, the Court cited statutory context. Dismissing the lower court's position, the Court explained that, while section 262( l )(8)(A) contains a single timing requirement—an applicant must provide notice 180 days prior to marketing—"[t]he Federal Circuit ... interpreted the provision to impose two timing requirements: The applicant must provide notice after the FDA licenses the biosimilar and at least 180 days before the applicant markets the biosimilar." The Supreme Court went on to explain that "'[h]ad Congress intended to' impose two timing requirements in §262( l )(8)(A)," it "presumably" would have structured those requirements parallel to the two timing requirements in the subparagraph that immediately follows. 
The Supreme Court's decision in Sandoz has the potential to hasten the pace at which a biosimilar can reach the market by effectively making the "patent dance" optional. In other words, under Sandoz an applicant can choose not to engage in the disclosure and negotiation process with the reference product sponsor prior to marketing in exchange for assuming increased litigation risks. By refusing to adopt the Federal Circuit's interpretation of the BCPIA, the Supreme Court rejected an interpretation of the Act that would have effectively added 180 days of exclusivity for the sponsor. Legal and industry experts have been vocal in their reactions to the Court's decision—some have questioned the meaningfulness of notice provided prior to approval, while others have suggested that the rejection of the availability of injunctive relief for enforcing a violation of the BPCIA effectively guts the protections Congress presumably sought to provide. There is also concern that by loosening the requirements of the BPCIA, the Court's decision may create more uncertainty for innovator companies, biosimilar companies, and ultimately the general public alike. For those who may question the outcome, Justice Breyer's concurrence offers an alternative—in line with his comments during oral argument, he stated that "if [FDA], after greater experience administering this statute, determines that a different interpretation would better serve the statute's objectives, it may well have authority to depart from, or to modify, today's interpretation." Whether or not FDA acts to address the implications of the Court's decision, Congress could, should it feel the Supreme Court's interpretation is not reflective of the policy decisions intended, amend the BPCIA to clarify its provisions.

	Emerging Issues in Patent Law

In addition to the effects of the patent decisions issued by the Supreme Court during its October 2016 Term, there are a number of patent-related issues on the horizon. Such issues stem from future Supreme Court cases to be heard during its next term; legislative proposals in Congress; and executive initiatives in the intellectual property area.

		Viability of Inter Partes Review Proceedings

As noted, the PTO's inter partes review proceedings are one of the major patent reforms made by the AIA, but their continued availability is contingent on the judgment of the Supreme Court. Specifically, on June 12, 2017, the Supreme Court granted certiorari in Oil States Energy Services v. Greene's Energy Group on the sole question as to "[w]hether inter partes review—an adversarial process used by the [PTO] to analyze the validity of existing patents—violates the Constitution by extinguishing private property rights through a non-Article III forum without a jury." While the Federal Circuit summarily dismissed the Oil States case (i.e., without a written opinion), it previously rejected a constitutional challenge to inter partes review proceedings in a written decision.
Specifically, in MCM Portfolio v. Hewlett-Packard , the Federal Circuit addressed whether inter partes review proceedings violate (1) Article III of the Constitution, by delegating issues to the PTO that must be adjudicated by a federal court, and (2) the Constitution's Seventh Amendment because there is no jury in PTO proceedings. Article III establishes the federal court system, providing that the "judicial Power shall extend to all Cases, in Law and Equity, arising under ... the Laws of the United States," while the Seventh Amendment provides: "In Suits at common law, where the value in controversy shall exceed twenty dollars, the right of trial by jury shall be preserved...." In rejecting the constitutional challenge, the Federal Circuit reasoned that:
The patent right derives from an extensive federal regulatory scheme, and is created by federal law. Congress created the PTO, an executive agency with specific authority and expertise in the patent law, and saw powerful reasons to utilize the expertise of the PTO for an important public purpose—to correct the agency's own errors in issuing patents in the first place.... There is notably no suggestion that Congress lacked authority to delegate to the PTO the power to issue patents in the first instance. It would be odd indeed if Congress could not authorize the PTO to reconsider its own decisions.
The Supreme Court denied certiorari in MCM Portfolio , while granting it in Oil States .
In its brief on the merits, filed on August 24, 2017, Oil States raises two main arguments. First, the company asserts that "[i]nter partes review impermissibly transfers the responsibility for deciding common-law suits from Article III judges to administrative agency employees who are beholden to Executive Branch officials—precisely the evil the Framers sought to avoid." Second, Oil States contends that "[i]nter partes review impermissibly supplants juries as well as judges," in violation of the Seventh Amendment. Greene's Energy Group's brief on the merits is currently due on October 23, 2017, while Oil States' reply is due November 20, 2017.
There appears to be much anticipation as to the outcome of this case. One commentator has stated that "[t]he Supreme Court's decision holds the potential to be one of the most significant patent decisions in decades." In deciding this case, the Supreme Court must determine whether a patent is a private property right , like real property, and therefore revocable only in an Article III tribunal, as opposed to a pub l ic right created by an administrative agency empowered to revoke that right. Notably, the Patent Act itself contains a provision stating "patents shall have the attributes of personal property." If the Court were to find that patents are private property rights and hold that inter partes review proceedings are unconstitutional, there would be a cascade of consequences for the U.S. patent regime.
Among the possible consequences experts are currently discussing is the question of what will happen to patents that were invalidated in inter partes review proceedings. Since the proceedings began in 2012, the PTO has received approximately 7,000 petitions and, of the more than 1,500 final decisions it has issued, roughly 1,300 have invalidated at least some patent claims. One commentator has framed the question this way: "'What happens to all those patents? Do they suddenly spring back to life?'" 
Relatedly, as discussed above, is the fact that the PTO invalidates patents through other administrative proceedings, including reexamination proceedings, which have been available since the 1980s. In addition to the question of the fate of patents invalidated during inter partes review proceedings is that of those invalidated during reexamination. Further, if the Supreme Court rules that inter partes review proceedings are unconstitutional, this will call into question the constitutionality of the PTO's other revocation proceedings, including reexamination and post-grant reviews.
Finally, should the Court hold that inter partes review proceedings are unconstitutional, the question of the impact on the caseload of the federal courts looms large. As noted, about 7,000 petitions for inter partes review proceedings have been filed in the last five years. While it is unlikely that all such petitions would amount to infringement complaints lodged in the federal courts, it seems likely that the elimination of PTO revocation proceedings will have a tangible effect on the dockets of the federal courts.
Notably, as of the date of this report, the only other patent case scheduled to be heard during the Court's October 2017 Term also involves inter partes review proceedings. In SAS Institute v. Matal , the Court granted certiorari to answer the following question:
Does 35 U.S.C. § 318(a), which provides that the [PTAB] in an inter partes review "shall issue a final written decision with respect to the patentability of any patent claim challenged by the petitioner," require that Board to issue a final written decision as to every claim challenged by the petitioner, or does it allow that Board to issue a final written decision with respect to the patentability of only some of the patent claims challenged by the petitioner, as the Federal Circuit held?
Under current PTO practice, a petitioner may challenge a patent "on all or some of the challenged claims," and the PTO may institute a proceeding on a subset of the petition's challenged claims. Obviously, the challenge as to whether the PTO must address all patent claims challenged by a petitioner will become moot if the Court strikes down inter partes review proceedings as unconstitutional in Oil States . Standing alone, however, SAS Institute also has implications for the PTO because it has the potential to eliminate a practice of the agency that allows it to manage its workload by limiting the number of challenged claims it must analyze.

		Legislative and Executive Patent Law Activity

As noted, patent reform appears to be of perennial concern to Congress. For instance, prior to the enactment of the AIA in 2011, there were several years of legislative activity in this area. With regard to patent reform, issues that have received attention include, but are not limited to: (1) remedies for patent infringement, including the availability of damages, injunctive relief, and attorney fees; (2) administrative proceedings before the PTO, such as those enacted in the AIA; (3) the issue of non-practicing entities (i.e., patent trolls); and (4) the high costs and burdens of patent litigation for U.S. businesses, and the costs that are passed on to consumers, particularly in the drug context.
Most recently, in the 115 th Congress, the Support Technology and Research for Our Nation's Growth and Economic Resilience Patents Act (STRONGER Patents Act) of 2017 was introduced. The bill's stated purpose is "to strengthen the position of the United States as the world's leading innovator by amending title 35 ... to protect the property rights of the inventors that grow the country's economy." The bill contains many provisions of the Support Technology and Research for Our Nation's Growth Patents Act of 2015 (STRONG Patents Act) of the 114 th Congress, as well as provisions from the Targeting Rogue and Opaque Letters Act of 2015 (TROL Act).
At center, the STRONGER Patent Act addresses the PTO's post-grant proceedings, with much of its provisions devoted to reforms of the inter partes review and post-grant review proceedings. For example, the bill would align the PTO's patent claim construction standard with that of the federal courts. The bill would also require that findings of patent invalidity by the PTO be proved by "clear and convincing" evidence, as they are in district court litigation. With regard to standing in PTO proceedings, the bill would limit potential petitioners to only those individuals and enterprises who have a demonstrated adverse relationship to the challenged patent to the exclusion of nonpracticing entities (i.e., patent trolls). In addition to provisions amending PTO administrative proceedings, Title II of the bill empowers the Federal Trade Commission to take certain enforcement actions against nonpracticing entities that send misleading patent-related demand letters.
While addressing some of the concerns raised in the Oil States litigation with regard to inter partes review, as one observer has noted, the bill may modify or overturn the holdings of at least five intellectual property-related Supreme Court cases from the past decade, including eBay Inc. v. MercExchange , Microsoft Corp. v. AT&T Corp. , Global-Tech Appliances v. SEB SA , Akamai Techs. v. Limelight Networks , and Cuozzo Speed Techs . v. Lee . The future of the Bill remains to be seen, but it should be noted that similar patent reform legislation introduced in prior Congresses, such as the STRONG Patents Act of 2015, did not lead to enactment.
Finally, on the executive front, the central policy pronouncement related to patents and intellectual property issued since President Donald Trump took office was the initiation of an investigation into China's intellectual property practices, including patent protection. On August 14, 2017, President Trump issued a presidential memorandum directing the United States Trade Representative (USTR) to "determine ... whether to investigate any of China's laws, policies, practices, or actions that may be unreasonable or discriminatory and that may be harming American intellectual property rights, innovation, or technology development" pursuant to section 301 of the Trade Act of 1974. The USTR initiated such an investigation on August 18, 2017, and is scheduled to convene a public hearing on October 10, 2017. While the investigation is in its early stages, it could result in remedial trade actions in response to a finding of unfair intellectual property practices, such as the suspension of trade agreement concessions or the imposition of duties or import quotas, among others.

Summary:
In an increase over prior terms, the Supreme Court of the United States issued six opinions involving patent law during its October 2016 Term. These decisions addressed issues ranging from patent exhaustion, multicomponent products, and biosimilar patents to procedural issues like venue and the statute of limitations for infringement claims. The growing number of Supreme Court opinions involving patent law over the past decade may also speak to the rising importance of intellectual property more broadly; a reported 84% of the S&P 500 Market Value in 2015 is ascribed to intangible assets. With this increased attention on patent law, an understanding of patent law and the cases issued during the High Court's recently concluded term will likely be of interest to Congress.
The patent law regime in the United States is grounded in the U.S. Constitution itself; article I, section 8, clause 8 of the Constitution provides: "The Congress Shall Have Power ... To promote the Progress of Science and useful Arts, by securing for limited Times to ... Inventors the exclusive Right to their respective ... Discoveries." Nonetheless, the rights associated with patents do not arise automatically. Rather, to obtain patent protection, the Patent Act of 1952 requires inventors to apply with the U.S. Patent and Trademark Office (PTO).
A patent may be obtained by "[w]hoever invents or discovers any new and useful process, machine, manufacture, or composition of matter," subject to the requirements of the Patent Act. A valid patent bestows upon its holder the right to take action against anyone who "makes, uses, offers to sell, or sells any patented invention, within the United States or imports into the United States any patented invention during the term of the patent," unless authority to do so is secured from the patent holder. In addition to examining patent applications, the PTO conducts other proceedings to determine the validity of issued patents, which can result in the revocation of previously issued patents. These proceedings play a central role in the country's patent system. Final decisions from the PTO are appealable to the U.S. Court of Appeals for the Federal Circuit, which has exclusive, nationwide jurisdiction over most patent appeals.
With the Supreme Court hearing an increasing number of cases involving patent law and other areas of intellectual property over the last decade, the Court is playing a larger role in the development of patent law. During its October 2016 Term, the Court issued two patent law opinions involving procedural issues that will affect when and where patent cases may be filed. In another pair of cases heard during the October 2016 Term, the High Court dealt with issues related to patents on multicomponent products—one in the context of determining infringement and another in the context of calculating damages. A final pair of patent cases decided during the Term may have major implications for the pharmaceutical industry—one addresses whether post-sale restrictions, commonly used in the pharmaceutical industry, are enforceable under patent law, and the other will likely affect the speed at which biosimilars come to market.
In addition to the effects of the Supreme Court's patent decisions issued during its October 2016 Term on patent law, there are a number of patent-related issues on the horizon. The constitutionality of one of the PTO's post-grant review proceedings has been called into question in a case that will be heard during the Court's upcoming October 2017 Term. In addition, with patent reform being of perennial concern to Congress, certain legislative proposals have the potential to alter various areas of patent law.
