Relation to other proceedings or actions
Status: in_force

(a) Infringer's Civil Action.—

(1) Post-grant review barred by civil action.—A post-grant review may not be instituted under this chapter if, before the date on which the petition for such a review is filed, the petitioner or real party in interest filed a civil action challenging the validity of a claim of the patent.

(2) Stay of civil action.—If the petitioner or real party in interest files a civil action challenging the validity of a claim of the patent on or after the date on which the petitioner files a petition for post-grant review of the patent, that civil action shall be automatically stayed until either—

(A) the patent owner moves the court to lift the stay;

(B) the patent owner files a civil action or counterclaim alleging that the petitioner or real party in interest has infringed the patent; or

(C) the petitioner or real party in interest moves the court to dismiss the civil action.

(3) Treatment of counterclaim.—A counterclaim challenging the validity of a claim of a patent does not constitute a civil action challenging the validity of a claim of a patent for purposes of this subsection.

(b) Preliminary Injunctions.—If a civil action alleging infringement of a patent is filed within 3 months after the date on which the patent is granted, the court may not stay its consideration of the patent owner's motion for a preliminary injunction against infringement of the patent on the basis that a petition for post-grant review has been filed under this chapter or that such a post-grant review has been instituted under this chapter.

(c) Joinder.—If more than 1 petition for a post-grant review under this chapter is properly filed against the same patent and the Director determines that more than 1 of these petitions warrants the institution of a post-grant review under section 324, the Director may consolidate such reviews into a single post-grant review.

(d) Multiple Proceedings.—Notwithstanding sections 135(a), 251, and 252, and chapter 30, during the pendency of any post-grant review under this chapter, if another proceeding or matter involving the patent is before the Office, the Director may determine the manner in which the post-grant review or other proceeding or matter may proceed, including providing for the stay, transfer, consolidation, or termination of any such matter or proceeding. In determining whether to institute or order a proceeding under this chapter, chapter 30, or chapter 31, the Director may take into account whether, and reject the petition or request because, the same or substantially the same prior art or arguments previously were presented to the Office.

(e) Estoppel.—

(1) Proceedings before the office.—The petitioner in a post-grant review of a claim in a patent under this chapter that results in a final written decision under section 328(a), or the real party in interest or privy of the petitioner, may not request or maintain a proceeding before the Office with respect to that claim on any ground that the petitioner raised or reasonably could have raised during that post-grant review.

(2) Civil actions and other proceedings.—The petitioner in a post-grant review of a claim in a patent under this chapter that results in a final written decision under section 328(a), or the real party in interest or privy of the petitioner, may not assert either in a civil action arising in whole or in part under section 1338 of title 28 or in a proceeding before the International Trade Commission under section 337 of the Tariff Act of 1930 that the claim is invalid on any ground that the petitioner raised or reasonably could have raised during that post-grant review.

(f) Reissue Patents.—A post-grant review may not be instituted under this chapter if the petition requests cancellation of a claim in a reissue patent that is identical to or narrower than a claim in the original patent from which the reissue patent was issued, and the time limitations in section 321(c) would bar filing a petition for a post-grant review for such original patent.

Effect of reissue
Status: in_force

The surrender of the original patent shall take effect upon the issue of the reissued patent, and every reissued patent shall have the same effect and operation in law, on the trial of actions for causes thereafter arising, as if the same had been originally granted in such amended form, but in so far as the claims of the original and reissued patents are substantially identical, such surrender shall not affect any action then pending nor abate any cause of action then existing, and the reissued patent, to the extent that its claims are substantially identical with the original patent, shall constitute a continuation thereof and have effect continuously from the date of the original patent.

A reissued patent shall not abridge or affect the right of any person or that person's successors in business who, prior to the grant of a reissue, made, purchased, offered to sell, or used within the United States, or imported into the United States, anything patented by the reissued patent, to continue the use of, to offer to sell, or to sell to others to be used, offered for sale, or sold, the specific thing so made, purchased, offered for sale, used, or imported unless the making, using, offering for sale, or selling of such thing infringes a valid claim of the reissued patent which was in the original patent. The court before which such matter is in question may provide for the continued manufacture, use, offer for sale, or sale of the thing made, purchased, offered for sale, used, or imported as specified, or for the manufacture, use, offer for sale, or sale in the United States of which substantial preparation was made before the grant of the reissue, and the court may also provide for the continued practice of any process patented by the reissue that is practiced, or for the practice of which substantial preparation was made, before the grant of the reissue, to the extent and under such terms as the court deems equitable for the protection of investments made or business commenced before the grant of the reissue.

The first paragraph follows the present section with some rearrangement in language. The second paragraph adds new provisions for the protection of intervening rights, the court is given discretion to protect legitimate activities which would be adversely affected by the grant of a reissue and things made before the grant of the reissue are not subject to the reissue unless a claim of the original patent which is repeated in the reissue is infringed.

The court before which such matter is in question may provide for the continued manufacture, use or sale of the thing made, purchased or used as specified, or for the manufacture, use or sale of which substantial preparation was made before the grant of the reissue, and it may also provide for the continued practice of any process patented by the reissue, practice, or for the practice of which substantial preparation was made, prior to the grant of the reissue, to the extent and under such terms as the court deems equitable for the protection of investments made or business commenced before the grant of the reissue."

(1) action is necessary because the contractor or assignee has not taken, or is not expected to take within a reasonable time, effective steps to achieve practical application of the subject invention in such field of use;

(2) action is necessary to alleviate health or safety needs which are not reasonably satisfied by the contractor, assignee, or their licensees;

Effective Date of 1998 Amendment

Pub. L. 105–289, §3(b), Oct. 27, 1998, 112 Stat. 2781, provided that: "The amendment made by subsection (a) [amending this section] shall apply to any plant patent issued on or after the date of the enactment of this Act [Oct. 27, 1998]."

Findings and Purposes

Pub. L. 105–289, §2, Oct. 27, 1998, 112 Stat. 2780, provided that:

"(a) Findings.—The Congress makes the following findings:

"(1) The protection provided by plant patents under title 35, United States Code, dating back to 1930, has historically benefited American agriculture and horticulture and the public by providing an incentive for breeders to develop new plant varieties.

"(2) Domestic and foreign agricultural trade is rapidly expanding and is very different from the trade of the past. An unforeseen ambiguity in the provisions of title 35, United States Code, is undermining the orderly collection of royalties due breeders holding United States plant patents.

"(3) Plant parts produced from plants protected by United States plant patents are being taken from illegally reproduced plants and traded in United States markets to the detriment of plant patent holders.

"(4) Resulting lost royalty income inhibits investment in domestic research and breeding activities associated with a wide variety of crops—an area where the United States has historically enjoyed a strong international position. Such research is the foundation of a strong horticultural industry.

"(5) Infringers producing such plant parts from unauthorized plants enjoy an unfair competitive advantage over producers who pay royalties on varieties protected by United States plant patents.

"(b) Purposes.—The purposes of this Act [see section 1 of Pub. L. 105–289, set out as a Short Title of 1998 Amendments note under section 1 of this title] are—

"(1) to clearly and explicitly provide that title 35, United States Code, protects the owner of a plant patent against the unauthorized sale of plant parts taken from plants illegally reproduced;

"(2) to make the protections provided under such title more consistent with those provided breeders of sexually reproduced plants under the Plant Variety Protection Act (7 U.S.C. 2321 et seq.), as amended by the Plant Variety Protection Act Amendments of 1994 (Public Law 103–349); and

"(3) to strengthen the ability of United States plant patent holders to enforce their patent rights with regard to importation of plant parts produced from plants protected by United States plant patents, which are propagated without the authorization of the patent holder."
35 U.S.C. § 322 (2024) — Title 35: PATENTS / Chapter 32 / Section 322: Petitions
Petitions
Status: in_force

(a) Requirements of Petition.—A petition filed under section 321 may be considered only if—

(1) the petition is accompanied by payment of the fee established by the Director under section 321;

(2) the petition identifies all real parties in interest;

(3) the petition identifies, in writing and with particularity, each claim challenged, the grounds on which the challenge to each claim is based, and the evidence that supports the grounds for the challenge to each claim, including—

(A) copies of patents and printed publications that the petitioner relies upon in support of the petition; and

(B) affidavits or declarations of supporting evidence and opinions, if the petitioner relies on other factual evidence or on expert opinions;

(4) the petition provides such other information as the Director may require by regulation; and

(5) the petitioner provides copies of any of the documents required under paragraphs (2), (3), and (4) to the patent owner or, if applicable, the designated representative of the patent owner.

(b) Public Availability.—As soon as practicable after the receipt of a petition under section 321, the Director shall make the petition available to the public.

L. 112–29 (35 U.S.C. 100 note), with certain exceptions and limitations, see section 6(f)(2), (3) of Pub. L. 112–29, set out as a note under section 321 of this title.
35 U.S.C. § 101 (2024) — Title 35: PATENTS / Chapter 10 / Section 101: Inventions patentable
Inventions patentable
Status: in_force

Whoever invents or discovers any new and useful process, machine, manufacture, or composition of matter, or any new and useful improvement thereof, may obtain a patent therefor, subject to the conditions and requirements of this title.

(July 19, 1952, ch. 950, 66 Stat. 797.)

Historical and Revision Notes

Based on Title 35, U.S.C., 1946 ed., §31 (R.S. 4886, amended (1) Mar. 3, 1897, ch. 391, §1, 29 Stat. 692, (2) May 23, 1930, ch. 312, §1, 46 Stat. 376, (3) Aug. 5, 1939, ch. 450, §1, 53 Stat. 1212).

The corresponding section of existing statute is split into two sections, section 101 relating to the subject matter for which patents may be obtained, and section 102 defining statutory novelty and stating other conditions for patentability.

Section 101 follows the wording of the existing statute as to the subject matter for patents, except that reference to plant patents has been omitted for incorporation in section 301 and the word "art" has been replaced by "process", which is defined in section 100. The word "art" in the corresponding section of the existing statute has a different meaning than the same word as used in other places in the statute; it has been interpreted by the courts as being practically synonymous with process or method. "Process" has been used as its meaning is more readily grasped than "art" as interpreted, and the definition in section 100(b) makes it clear that "process or method" is meant. The remainder of the definition clarifies the status of processes or methods which involve merely the new use of a known process, machine, manufacture, composition of matter, or material; they are processes or methods under the statute and may be patented provided the conditions for patentability are satisfied.

"(b) Effective Date.—

"(1) In general.—Subsection (a) shall apply to any application for patent that is pending on, or filed on or after, the date of the enactment of this Act [Sept. 16, 2011].

"(2) Prior applications.—Subsection (a) shall not affect the validity of any patent issued on an application to which paragraph (1) does not apply."

Institution of post-grant review
Status: in_force

(a) Threshold.—The Director may not authorize a post-grant review to be instituted unless the Director determines that the information presented in the petition filed under section 321, if such information is not rebutted, would demonstrate that it is more likely than not that at least 1 of the claims challenged in the petition is unpatentable.

(b) Additional Grounds.—The determination required under subsection (a) may also be satisfied by a showing that the petition raises a novel or unsettled legal question that is important to other patents or patent applications.

(c) Timing.—The Director shall determine whether to institute a post-grant review under this chapter pursuant to a petition filed under section 321 within 3 months after—

(1) receiving a preliminary response to the petition under section 323; or

(2) if no such preliminary response is filed, the last date on which such response may be filed.

(d) Notice.—The Director shall notify the petitioner and patent owner, in writing, of the Director's determination under subsection (a) or (b), and shall make such notice available to the public as soon as is practicable. Such notice shall include the date on which the review shall commence.

(e) No Appeal.—The determination by the Director whether to institute a post-grant review under this section shall be final and nonappealable.
