CAFC: Parties Joined in IPRs are Not Estopped from Raising New Invalidity Grounds in District Court

On September 24, the United States Court of Appeals for the Federal Circuit (CAFC) affirmed-in-part and reversed-in-part the U.S. District Court for the Eastern District of Texas’s claim construction and remanded to the district court in Network-1 Technologies, Inc. v. Hewlett-Packard Company. In particular, the CAFC concluded that the district court erred in construing the claim term “main power source” and held that a party joined to an inter partes review (IPR) proceeding is not estopped from raising new invalidity grounds in district court, since the joinder provision does not allow parties to raise grounds not already instituted. The CAFC ultimately affirmed-in-part, reversed-in-part, vacated and remanded the district court’s judgment for a new trial on infringement.

Acer v. Intellisoft Petition Rebukes CAFC for Disrespecting SCOTUS Precedent, Ignoring District Court

Greenberg Traurig and The Rader Group – which is headed by retired Chief Judge of the U.S. Court of Appeals for the Federal Circuit, Randall Rader – have submitted a petition for certiorari to the U.S. Supreme Court on behalf of Acer America Corp. asking the Court to review the CAFC’s precedential opinion in Intellisoft v. Acer. On April 3, the CAFC held that the United States District Court for the Northern District of California (the district court) erred in refusing to remand a case to California state court where removal to a district court was improper under 28 U.S.C. § 1441 and §1454. Despite Acer’s contentions, the CAFC found that Intellisoft’s trade secret misappropriation claim did not “necessarily” raise patent law issues that would result in district court original jurisdiction.

Federal Circuit Vacates District Court Invalidity Judgment Based on Judicial Estoppel

On August 28, the United States Court of Appeals for the Federal Circuit (CAFC) affirmed the U.S. District Court for the District of Massachusetts’ claim construction in Egenera, Inc. v. Cisco Systems, Inc., but vacated the court’s invalidity judgment based on judicial estoppel and remanded for further proceedings. Egenera, Inc. (Egenera) owned U.S. Patent No. 7,231,430 (the ’430 patent), which was based on a provisional patent application filed in 2001 and was directed to a platform for automatically deploying a scalable and reconfigurable virtual network. In 2016, Egenera filed suit against Cisco in the district court for infringement of the ’430 patent. Cisco then filed an inter partes review (IPR) Petition with the United States Patent and Trademark Office’s (USPTO) Patent Trial and Appeal Board (PTAB) challenging the validity of the asserted claims.

Federal Circuit Affirms District Court Claim Construction in Foundation Pile Patent Infringement Dispute

The United States Court of Appeal for the Federal Circuit recently upheld the Central District of California’s ruling of summary judgment that certain accused products of Foundation Constructors, Inc. and Foundation Pile, Inc. (Foundation) do not infringe certain claims of U.S. Patent Nos. 7,914,236 (the ’236 patent) and 9,284,708 (the ’708 patent) (collectively, the patents-in-suit) after plaintiffs-appellants Steve Neville, Substructure Support, Inc., and TDP Support, Inc. (collectively, Substructure) appealed the district court’s ruling, as based on an improper claim construction. See Neville v. Found. Constructors, Inc., No. 2020-1132, 2020 U.S. App. LEXIS 27321 (Fed. Cir. Aug. 27, 2020) (Before Lourie, O’Malley, and Chen, Circuit Judges) (Opinion for the Court, Chen, Circuit Judge).

Federal Circuit Remands District Court Decision for Erroneous Claim Construction

On August 27, the United States Court of Appeals for the Federal Circuit (CAFC) reversed and remanded a decision of the U.S. District Court for the District of Delaware in Baxalta Inc. v. Genentech, Inc. The CAFC reversed the district court’s claim construction of the terms “antibody” and “antibody fragment” in Baxalta’s patent claims and remanded for proceedings consistent with the correct constructions.

VoIP-Pal Implores Full CAFC to Review Whether a Rule 12 Motion Based on Section 101 Can Be Decided Before Claim Construction

Last week, VoIP-Pal.com, Inc. filed a combined petition for panel rehearing and rehearing en banc with the U.S. Court of Appeals for the Federal Circuit (CAFC) asking for review of a Rule 36 judgment in VoIP-Pal.Com, Inc. v. Twitter, Inc. That judgment affirmed a decision of the U.S. District Court for the Northern District of California that resolved a claim construction dispute in the context of a motion to dismiss under Section 101 as per Rule 12(b)(6) of the Federal Rules of Civil Procedure prior to claim construction. In the petition, VoIP-Pal asserted that the Rule 36 judgment conflicted with CAFC precedent and “the time has come for this court to reconsider whether a Rule 12 motion based on §101 should be decided before claim construction.”

CAFC Partially Reverses PTAB on Claim Construction Analysis, Says Prosecution History Matters

The Federal Circuit on Friday reversed the Patent Trial and Appeal Board’s decision holding certain claims of Personalized Media Communications, LLC’s (PMC’s) U.S. Patent No. 8,191,091 (the ’091 Patent) unpatentable on anticipation and obviousness grounds but affirmed the decision as to the remaining claims. The Court found that the Board erred in its claim construction of one of the claim terms at issue due to its dismissal of the prosecution history. The Board rejected PMC’s reliance on the prosecution history, stating “the prosecution history presents a murky picture as opposed to a clear waiver.” The Federal Circuit disagreed with this approach and found that the prosecution history statements supported PMC’s interpretation and construction of the phrase “encrypted digital information transmission.”

On Claim Construction, Predictability, and Patent Law Consistency: The Federal Circuit Needs to Vote En Banc

The Federal Circuit needs to go en banc more often. That is the unmistakable lesson not just in light of the Supreme Court’s recent denials of certiorari on the hot questions of patent law, such as Section 101 and its application to diagnostic testing, or to whether Section 101 involves underlying factual questions. It is also tied into the very reason that Congress created the court in 1982: to provide predictability, stability, and clarity for the U.S. patent laws and system. Without these attributes, the patent system suffers—who, after all, wants to invest in patents where the governing rules are unclear or unpredictable?

Recent USPTO Update Provides Blueprint for PTAB Patent Challenge Process

Since the passing of the America Invents Act (AIA) and the implementation of the inter partes review (IPR) process, IPR has become a popular and important avenue for companies and individuals to challenge the validity of a patent in an administrative proceeding through the U.S. Patent and Trademark Office (USPTO). In the past five years, patent owners and challengers alike have presented new and sometimes novel challenges to the way the Patent Trial and Appeal Board (PTAB), comprised of a panel of administrative law judges that review and decide cases, conduct trial proceedings, causing the PTAB to reevaluate and tweak the process along the way. Building on the scores of changes and interpretations the PTAB has made since the first AIA trial, the USPTO provided guidance in August 2018 and more recently in July 2019 summarizing and clarifying how the PTAB handles the IPR process.  On November 20, 2019, the Patent Office issued a consolidated Office Patent Trial Practice Guide (“Practice Guide”) incorporating the updates from August 2018 and July 2019, providing practitioners with a single streamlined blueprint for the overall review process.

Congress Includes an Ugly Sweater in the STRONGER Patents Act

It is not unusual for there to be unintended consequences in the law or life. A loved one gives you something you don’t really like, but you do such a good job of feigning happiness that it becomes a regular gift. Who knew you could ever have too many “lovely” ties or too much single malt Scotch? Congress is in the process of giving the patent bar some welcome relief on some important issues, but may be throwing in that unwanted gift along with it. The STRONGER Patents Act intends to address the potential for inconsistent rulings between district court cases and inter partes reviews (IPRs). The Act achieves this by expressing a preference for district court rulings and by requiring IPRs to apply the same standards for validity determinations that are used in the district court. This is already the case by USPTO regulation with respect to claim construction, but the Act would make it statutory for both claim construction and validity, and thus not subject to change by the USPTO. While the use of the same standard for validity in both forums will make the rulings more consistent, the statutory preference for the district court over the IPR may have an unintended consequence.

Professors Expand Upon Proposals to Senate IP Subcommittee for Improving Patent Quality

On October 30, the Senate Judiciary Committee’s Subcommittee on Intellectual Property heard from five witnesses on ways to improve patent quality at the United States Patent and Trademark Office (USPTO). The Subcommittee subsequently posed questions to the witnesses, including professors Colleen Chien, R. Polk Wagner, and Melissa Wasserman, to supplement their testimony. Those witnesses have now submitted their responses, which expand upon their various suggestions for improving patent quality.

Recent PTAB Decisions Provide a Roadmap for Combating Broadest “Unreasonable” Interpretation

As I have previously reported on KSJ Law, the Patent Trial and Appeal Board (PTAB) issued 80 decisions on appeals in October, and reversed the examiner in 24 of those. Claim construction was at issue in several, and the PTAB made several comments, supported by case law, that will be useful to those laboring against “broadest reasonable interpretations” that are, in fact, not reasonable. Taken together, these recent decisions provide a road map for first arguing against a broadest reasonable interpretation that is overly broad and unreasonable, thereby supporting the conclusion that a prima facie case against the properly construed claims has not been made.

Federal Circuit Decision Delays Generic Osteoarthritis Drug

On October 9, the U.S. Court of Appeals for the Federal Circuit (CAFC) issued a decision in HZNP Medicines LLC v. Actavis Laboratories UT, Inc. affirming the U.S. District Court for the District of New Jersey’s findings of invalidity and noninfringement of certain claims of some of the asserted HZNP (Horizon) patents, as well as the district court’s finding of nonobviousness of one claim of another Horizon patent. The finding of nonobviousness means that Actavis, owned by generic drug maker Teva Pharmaceuticals, is enjoined from engaging in the commercial use, offer for sale, or sale of its product covered in its Abbreviated New Drug Application (ANDA) until the expiration of U.S. Patent No. 9,066,913 (the ‘913 patent) in 2027.

CAFC: Claim Construction That Misreads Plain Language of Claims and Specification Is Clearly Erroneous

The Federal Circuit recently vacated a district court decision which found a patent for the antipsychotic drug “Saphris,” belonging to Forest Laboratories (Forest), valid as nonobvious, but not infringed by ANDA filers Alembic Pharmaceuticals Ltd. (Alembic) and Breckenridge Pharmaceuticals, Inc. (Breckenridge). See Forest Labs., LLC v. Sigmapharm Labs., LLC, Nos. 2017-2369, 2017-2370, 2017-2372, 2017-2373, 2017-2374, 2017-2375, 2017-2376, 2017-2389, 2017-2412, 2017-2436, 2017-2438, 2017-2440, 2017-2441, 2019 U.S. App. LEXIS 7485 (Fed. Cir. Mar. 14, 2019) (Before Prost, Dyk, and Moore, J.) (Opinion for the court, Moore, J.). The Court highlighted an unanswered question that the district court skimmed over at trial and took issue with a claim construction. The Court vacated and remanded for further proceedings on this basis. Alembic and Breckenridge were among a number of drug manufacturers that filed Abbreviated New Drug Applications (ANDA) to market generic versions of Saphris. Saphris is an antipsychotic containing asenapine maleate. Saphris is administered sublingually, meaning under the tongue. Forest sued the ANDA filers for patent infringement. At trial, the district court held that the relevant claims of asserted Patent No. 5,763,476 (“the ’476 patent”) were not invalid as obvious, and that Forest had not established infringement by Alembic or Breckenridge. Alembic and Breckenridge appealed the invalidity determination, and Forest cross-appealed the non-infringement decision as clearly erroneous. On appeal, the Federal Circuit vacated and remanded both the validity and infringement determinations for reconsideration under a correct claim construction of the term “excitation.”

Federal Circuit Corrects District Court’s Claim Construction

The United Stated Court of Appeals for the Federal Circuit recently held that a district court erred in its claim construction and vacated the district court’s judgment of noninfringement, which the parties stipulated to based on the erroneous construction. See Continental Circuits LLC v. Intel Corp., No. 2018-1076, 2019 U.S. App. LEXIS 3920, 2019 WL 489069 (Fed. Cir. Feb. 8, 2019) (Before Lourie, Linn, and Taranto, J.) (Opinion for the court, Lourie, J.). The Court highlighted that the first step in claim construction should always be to determine the plain and ordinary meaning of the claims. Further, the specification should serve to limit the plain and ordinary meaning only when it includes a definition for a claim term or a clear disclaimer or disavowal of claim scope.
