Document:
Post-issuance review and reexamination proceedings are frequently used to address patent validity issues at the Patent Trial and Appeal Board (PTAB) in parallel with, or as an alternative to, federal district court cases. The interplay between litigation and patent office trials and reexamination is complex and extensive. Choosing an appropriate strategy may involve issues with conflicting priorities where each proceeding may impact another, including claim construction, admissions impacting infringement, claim amendments, estoppel against further validity challenges, entitlement to injunctive relief, intervening rights, vacatur of trial court judgments and enhanced damages.
Given this substantial interrelationship, it is essential—especially in high-stakes matters with significant strategic complexity—to hire a legal team that seamlessly integrates in-depth experience in patent post-issuance review, reexamination and litigation. Irell & Manella LLP offers this unique combination. Our practice combines one of the nation’s premier litigation practices with substantial experience in PTAB proceedings, including inter partes review (IPR), covered business method review and ex parte reexamination.
Our Patent Office Trials team includes Michael Fleming, former chief administrative patent judge of the PTAB. As chief judge, he assisted Congress in drafting the post-grant provisions of the America Invents Act (AIA) and played a critical role in the creation of the IPR statute. During more than 30 years with the U.S. Patent and Trademark Office (USPTO), including 17 years as an administrative patent judge, he helped establish many of its present patent procedures and policies, including several of the examination guidelines and the federal rules for patent office examination. Judge Fleming was responsible for many of the precedential opinions that are currently binding on administrative patent judges of the PTAB. He also instituted the official standard operating procedure for issuing precedential opinions that establish binding precedent on issues before the PTAB and aid in developing best examination practices.
Irell’s team boasts more than 20 registered patent lawyers, including former patent examiners and Federal Circuit clerks. Many of our partners bring to the practice substantial professional experience working in the technology industry, as well as advanced technical degrees in areas such as computer engineering, computer science, chemical engineering, electrical engineering, mechanical engineering, inorganic chemistry, physics, materials science, molecular pharmacology and pharmacy. Our team also has extensive connections with scientists, engineers and technologists who can provide expert testimony in PTAB proceedings.
Apple Inc. v. Immersion Corporation. Represented Immersion in nine IPRs brought by Apple over patents related to haptics technology used in the current generation of iPhones, MacBooks and the Apple Watch. Irell persuaded the PTAB to deny institution.
Pfizer v. Genentech and Biogen. Represented Genentech and Biogen in these IPR proceedings against patents protecting their blockbuster drug Rituxan, a treatment for various forms of cancer, rheumatoid arthritis and other serious diseases. Irell convinced the PTAB not to institute these IPR proceedings.
Amkor Technology, Inc. v. Tessera, Inc. Secured a victory in an IPR trial before the PTAB. In an attempt to void an arbitration award, Amkor filed an IPR against the semiconductor manufacturing patent responsible for the majority of damages. The PTAB affirmed the patentability of every one of the 14 claims that Tessera contended was patentable and on every one of the claims that Amkor was found to have used.
Sienna Biopharmaceutical, Inc. v. William March Rice University. Representing Sienna Biopharmaceutical challenging Rice's therapeutic nanoparticles methods patents. Irell prevailed in the IPR, with the PTAB cancelling all challenged claims.
Symantec Corp. v. Trustees of Columbia University. Prevailed at trial before the PTAB on five Symantec IPRs challenging the validity of four of Columbia's data security patents. Also prevented institution on two Columbia patents.
Juniper Networks, Inc. v. Brixham Solutions, LTD. Represented Juniper in two IPR proceedings involving router technology. The PTAB invalidated each of the claims from the two patents that Brixham Solutions Ltd. had asserted against Juniper in Northern California, finding that all of the asserted claims were rendered obvious by the prior art Juniper had identified in its petitions. The PTAB also denied Brixham’s motions to exclude the declarations of Juniper’s technical expert in both proceedings.
Celltrion Inc. v. Genentech and Biogen. Represented Genentech and Biogen in these IPR proceedings brought by Celltrion of the patents protecting their blockbuster drug Rituxan, a treatment for various forms of cancer, rheumatoid arthritis and other serious diseases. Irell prevailed by preventing institution of these proceedings.
Apple, Inc. v. Wisconsin Alumni Research Foundation. Represented patent owner Wisconsin Alumni Research Foundation (WARF) in an IPR proceeding brought by Apple, which filed the petition as part of the ongoing litigation between the parties on Apple’s unauthorized use of WARF’s memory disambiguation technology. WARF defeated Apple’s attempt to shield from the board highly relevant and damaging admissions from its own witnesses. The PTAB declined to commence an IPR on any grounds asserted in Apple’s petition.
Samsung Electronics Co, LTD. v. KAIST IP US LLC. Representing the licensing representative for the Korean Advanced Institute of Science and Technology, Irell convinced the PTAB not to institute the IPR proceedings involving a fundamental patent relating to bulk FinFET technology.
Mylan Pharmaceuticals Inc. v. Gilead Sciences, Inc. Defeated challenges brought by Mylan Pharmaceuticals to four Gilead patents related to the HIV drug tenofovir disoproxil fumarate. The PTAB declined to institute IPR proceedings on all four petitions.
Legend3D, Inc. v. Prime Focus Creative Services Canada Inc. Represented Prime Focus in an IPR brought by Legend3D in an attempt to invalidate Prime Focus’s 3D technology patent and persuaded the PTAB to deny institution.
Apple v. Papst Licensing GMBH & Co. Represented Papst Licensing in IPRs concerning an interface device for communication between a computer host device and a data transmit/receive device. Irell persuaded the PTAB to deny institution.
Nipro Corporation v. NxStage Medical. Secured a win for a pioneer in high-efficiency blood tubing sets for extracorporeal blood handling applications, defeating a challenge by competitor Nipro Corporation. The Irell team employed recently adopted PTAB rules governing the early submission of expert testimony to argue that Nipro’s proposed constructions were unreasonably broad. The PTAB agreed that Nipro’s constructions were unreasonable and denied institution of the IPR on that basis.
Kite Pharma v. Sloan Kettering Institute for Cancer Research. Prevailed on behalf of Sloan Kettering and its exclusive licensee, Juno Therapeutics, a clinical-stage biotechnology company developing cellular immunotherapies for the treatment of cancer. Kite sought to invalidate all claims of a patent covering a chimeric T cell technology. The USPTO upheld all the claims of the patent.
The General Hospital Corp. v. Sienna Biopharmaceutical, Inc. Secured a win for Sienna, a developer of groundbreaking products to treat acne and hair removal. General Hospital Corp. (GHC) sought to invalidate Sienna’s patent by having an interference declared with GHC’s patent application in which GHC copied Sienna’s claims, presumably to clear the way for GHC hair removal products. Irell convinced the PTAB that the interfering GHC patent application lacked written description support. This led the PTAB to enter a judgment of validity for Sienna and to find GHC's patent application unpatentable.
B/E Aerospace, Inc. v. MAG Aerospace Industries LLC. Represented B/E Aerospace in IPRs filed against a competitor in the field of aircraft water and waste systems. The IPRs were requested on patents that MAG asserted in a concurrent patent infringement action against B/E in district court. B/E prevailed on noninfringement in court. The USPTO also invalidated all of the challenged claims of the three patents, concluding that they were obvious based on prior art.
Cisco Systems, Inc. v. Constellation Technologies LLC. Secured a series of wins for patent owner Constellation Technologies LLC. Constellation managed a patent portfolio on fundamental networking technologies that were developed by Nortel Networks Ltd. The PTAB declined to institute on four IPR petitions, ruling that Cisco has not shown a reasonable likelihood of prevailing.
Palo Alto Networks (PAN) v. Juniper Networks, Inc. Represented Juniper in two IPRs filed by a competing provider of networking hardware. These IPRs were part of a long-running dispute with a competing company founded by former employees who left Juniper to compete in the same field. The IPRs were resolved through a $175 million settlement payment to Juniper and termination of the IPRs with Juniper’s patents fully intact.
MaxLinear, Inc. v. Cresta Technology Corp. Represented Cresta in this IPR proceeding related to multi-format television tuners. The PTAB declined to institute IPR proceedings.
