​On March 13, 2023, the United States Court of Appeals for the Federal Circuit (“CAFC”) affirmed-in-part and reversed-in-part an order of the United States District Court for the Northern District of California (N.D. Cal.) dismissing as unreviewable a lawsuit challenging the instructions of the Director of the U.S. Patent and Trademark Office (“USPTO”) regarding the standard for discretionary denial of petitions for inter partes review (IPR) based on pending parallel litigation involving the same patents.  Apple Inc. v. Vidal, No. 2022-1249, —F.4th— (Fed. Cir. Mar. 13, 2023).  The CAFC affirmed the unreviewability dismissal of the challenge to the Fintiv instructions as contrary to statute and arbitrary and capricious but reversed and remanded the dismissal of the challenge to the instructions as improperly issued without a notice-and-comment period.

On February 24, 2023, the United States Court of Appeals for the Federal Circuit (CAFC) reversed a final written decision by the Patent and Trademark Office’s Patent Trial and Appeal Board (“PTAB”), finding the challenged claim not unpatentable as obvious.  Intel Corp. v. PACT XPP Schweiz AG, No. 2022-0138 (Fed. Cir. Feb. 24, 2023).  In doing so, the CAFC held that the PTAB improperly required the petitioner to show the prior art references could be “bodily incorporated.”

On February 10, 2023, Director of the U.S. Patent & Trademark Office Katherine K. Vidal issued a decision affirming a Patent Trial and Appeal Board decision to deny institution of inter partes review. Xerox Corp. v. Bytemark, Inc., IPR2022-00624, Paper 12 (Feb. 10, 2023). The Board had found, and Director Vidal agreed, that Petitioners’ expert testimony was entitled to little weight because it merely repeated, verbatim, the conclusory arguments in the petition itself. Director Vidal’s decision is “word from the top” that the practice of simply “parroting” a petition’s arguments in the expert declaration is strongly disfavored and unlikely to carry the day on invalidity.

On February 8, 2023, in a precedential order, the United States Court of Appeals for the Federal Circuit (CAFC) affirmed the decision by the Director of the U.S. Patent and Trademark Office to deny CyWee Group Ltd.’s (“CyWee’s”) request for rehearing of two IPR proceedings.  In doing so, the CAFC rejected CyWee’s argument that the Director is required to actually review, or be able to review, all institution decisions and final written decisions within the statutory time frames set by 35 U.S.C. §§ 316(a)(11) and 314(b).  CyWee Group Ltd. v. Google LLC, No. 2020-1565 (Fed. Cir. Feb. 8, 2023).
 

On November 14, 2022, the United States Court of Appeals for the Federal Circuit (CAFC) affirmed a decision by the Patent Trial and Appeal Board (PTAB) allowing claim amendments during inter partes review (IPR) proceedings that addressed issues additional to those raised by the grounds relied upon for institution of the IPR.

The Court found that the PTAB had not erred when it permitted Sleep Number, the patent owner, to submit claim amendments in IPR that addressed Section 112 issues (which were additional to amendments addressing the instituted grounds).

On October 4, 2022, the Director of the United States Patent and Trademark Office (the “Director”) issued a precedential decision finding that the conduct of Petitioner OpenSky Industries, LLC (“OpenSky”) was an abuse of process, sanctioning Petitioner, and remanding to the Patent Trial and Appeal Board (the “Board”) for further proceedings.  OpenSky Industries, LLC v. VLSI Technology LLC, IPR2021-01064, Paper 102 (P.T.A.B. Oct. 4, 2022).

Elekta Inc., Nos. 2021-2099, 2021-2100 (Fed. Cir. Aug. 29, 2022).  The CAFC held, inter alia, that Appellant patentee lacked standing to appeal the PTAB’s IPR unpatentability decision with respect to a claim that Appellant previously had canceled in an ex parte reexamination (“reexamination”).

On August 17, 2022, the Federal Circuit reversed a district court’s grant of summary judgment of invalidity, finding that IPR estoppel under 35 U.S.C. § 315(e)(2) barred Ingenio, Inc.’s invalidity argument, even though the challenged claim had not been addressed by the PTAB in the final written decision in Ingenio’s IPR.  Click-to-Call Techs. LP v. Ingenio, Inc., No. 2022-1016 (Fed. Cir. Aug. 17, 2022).

On August 12, 2022, the U.S. Court of Appeals for the Federal Circuit (“CAFC”) affirmed the decision of the Patent Trial and Appeal Board (“PTAB”), which found unpatentable the challenged claims of a patent relating to housings for ultrasonic flow meters.

Intuitive Surgical Operations, __ F.4th __ (Fed. Cir. April 29, 2022).

On March 18, 2022, the Patent Trial and Appeal Board of the United States Patent and Trademark Office exercised its discretion under 35 U.S.C. § 314(a) to deny institution of a petition for inter partes review filed by Google LLC challenging a patent asserted against it in an ITC investigation and a parallel district court case. Google LLC v. EcoFactor, Inc., IPR2021-01578, Paper 9 (PTAB Mar. 18, 2022).  The PTAB’s denial relied primarily on the late stage of the ITC investigation.

On February 2, 2022, the United States Court of Appeals for the Federal Circuit vacated a decision from the Patent Trial and Appeal Board of the U.S. Patent and Trademark Office, finding that the Board erred in concluding that applicant admitted prior art (“AAPA”) constitutes “prior art consisting of patents or printed publications” under 35 U.S.C. § 311(b).  Qualcomm Inc. v. Apple Inc., __ F.4th __ (Fed. Cir. Jan. 27, 2022).

NetScout Systems, Inc., 2-20-cv-00349.

​On December 8, 2021, the Court of Appeals for the Federal Circuit (“CAFC”) affirmed the decision of the Patent Trial and Appeal Board  (“Board”), finding that petitioner Lenovo Holding Company, Inc. (“Lenovo”) had failed to show by a preponderance of the evidence that the claims it challenged in an inter partes review (“IPR”) were unpatentable.  Lenovo Holding Company, Inc. v. DoDots Licensing Solutions LLC, __ F.4th __ (Fed. Cir. Dec. 8, 2021).

On December 1, 2021, the United States Court of Appeals for the Federal Circuit (CAFC) issued two opinions related to the same inter partes review (IPR) petitioner’s standing to appeal two decisions of the Patent Trial and Appeal Board (PTAB).  ModernaTx, Inc. v. Arbutus Biopharma Corp, — F.4th — (Fed. Cir. Dec. 1, 2021); ModernaTx, Inc. v. Arbutus Biopharma Corp f/k/a Protiva Biotherapeutics, Inc., — F.4th — (Fed. Cir. Dec. 1, 2021).  In the first opinion, the CAFC found that petitioner had established standing by demonstrating a sufficient risk of an infringement suit based on the patent owner’s statements and actions.  In the second opinion, the CAFC found that petitioner lacked standing at the time the appeal was filed because petitioner’s evidence of financial burden from the validity of the patent at issue was too speculative.

On October 13, 2021, the U.S. Court of Appeals for the Federal Circuit (CAFC) issued an opinion rejecting a patentee’s arguments challenging the constitutionality of the U.S. Patent and Trademark Office’s (USPTO’s) structure based on its purported financial interest in instituting inter partes reviews (IPRs).  Mobility Workx, LLC v. Unified Patents, LLC, --- F.3d --- (Fed. Cir. Oct. 13, 2021).  The CAFC found that the financial interests of the Patent Trial and Appeal Board (PTAB) leadership and of individual administrative patent judges (APJs) were too remote to violate due process under the U.S. Supreme Court’s decision in Tumey v. Ohio.

On July 21, 2021, the United States District Court for the Eastern District of Texas, Marshall Division, denied plaintiff’s motion for summary judgement that its patent was not invalid due to inter partes review (“IPR”) estoppel pursuant to 35 U.S.C. § 315(e)(2).  General Access Solutions, Ltd. v.

Next Caller Inc., Slip. Op. (D. Del. July 6, 2021).  The Court determined that plaintiff was not collaterally estopped.

On April 13, 2021, the Court of Appeals for the Federal Circuit (CAFC) issued an opinion affirming the decision of the U.S. Patent and Trademark Office’s Patent Trial and Appeal Board (PTAB), finding that the claims of the challenged patent had not been proved obvious because the petition for inter partes review (IPR) failed to show that there would have been a motivation to combine the two allegedly invalidating prior art references.  Apple Inc. v. INVT SPE LLC, —F.3d — (Fed. Cir. Apr. 13, 2021).

On March 9, 2021, the United States Court of Appeals for the Federal Circuit (“CAFC”) issued an opinion affirming estoppel and obviousness rulings by the U.S. Patent and Trademark Office’s Patent Trial and Appeal Board (“PTAB”).  Uniloc 2017 LLC v. Facebook Inc., ___ F.3d ___ (Fed. Cir. March 9, 2021).  The CAFC ruled that it had jurisdiction to review the PTAB’s decision as to estoppel related to the inter partes review (“IPR”) estoppel provision of Section 315(e)(1).  The CAFC further ruled that a joined party to a first IPR was not barred from maintaining review of claims that the primary challenger became estopped from challenging based on a decision in a second IPR to which the challenger was joined.
 

On February 24, 2021, the Court of Appeals for the Federal Circuit (CAFC) issued an opinion affirming the obviousness decision of the U.S. Patent and Trademark Office’s Patent Trial and Appeal Board (PTAB). Daikin Indus., LTD v. The Chemours Co. FC, LLC, __ F.3d __ (Fed. Cir.

On November 18, 2020, the U.S. Patent and Trademark Office’s Patent Trial and Appeal Board (PTAB) denied institution of a petition for inter partes review (IPR).  Google LLC v. EcoFactor Inc., case no. IPR2020-00946 (PTAB Nov. 18, 2020).  In its decision, the PTAB exercised its discretion under 35 U.S.C. § 314(a) to deny institution because of a co-pending investigation before the International Trade Commission (ITC) involving the challenged patent.
 

On October 6, 2020, the U.S. Patent and Trademark Office’s Patent Trial and Appeal Board (PTAB) instituted an inter partes review (IPR) proceeding, rejecting Patent Owner’s argument that the PTAB should exercise its discretion under 35 U.S.C. § 325(d) to deny institution because the same prior art and arguments were before the Patent Office Examiner during original prosecution.  Sony Interactive Entertainment LLC v. Bot M8, LLC, Case No. IPR2020-00726 (PTAB Oct. 6, 2020).  In doing so, the PTAB agreed with Petitioner that the Examiner overlooked a reference’s teaching.

SIPCO, LLC, __ F.3d __ (Fed. Cir. Sept. 30, 2020).

Hewlett-Packard Co., __ F.3d __ (Fed. Cir. Sept. 24, 2020).  In its decision, the CAFC vacated the district court’s judgment of non-infringement as based on incorrect claim construction, vacated the district court’s judgment as a matter of law (“JMOL”) on validity for improperly applying statutory estoppel, and affirmed the district court’s decision with respect to improper claim broadening.
 

On September 8, 2020, the United States International Trade Commission (“ITC”) issued an opinion suspending enforcement of remedial orders pending appeal of the Patent Trial and Appeals Board’s (“PTAB”) final written decision (“FWD”) of unpatentability in a parallel inter partes review (“IPR”) proceeding.  Certain Unmanned Aerial Vehicles and Components Thereof, Inv. No. 337-TA-1133, Comm’n Op. (Sept. 8, 2020); Certain Unmanned Aerial Vehicles and Components Thereof, Inv. No. 337-TA-1133, Final Determination (Aug. 20, 2020).  In its opinion, the ITC relied on its broad discretion in selecting a remedy, its recognition of the PTAB’s leading role in assessing the validity of patent claims, and Congress’s goal for IPRs to be a substitute for litigation on patent validity issues.

Luv N’ Care, Ltd., No. 2019-1454, __ F.3d __ (Fed. Cir. Jun. 8, 2020).  The CAFC found that the CDCA abused its discretion because the facts relied upon by the movant did not support a determination that plaintiff acted unreasonably in bringing and maintaining its case.
 

On May 22, 2020, the Patent Trial and Appeal Board (“PTAB”) of the U.S. Patent and Trademark Office issued a decision instituting inter partes review (“IPR”) over Patent Owner’s argument that the PTAB should exercise its discretion to deny institution because the IPR petition relied on several references that were considered by the patent examiner during prosecution of the application leading to the patent-at-issue.  Medacta USA, Inc. v. RSB Spine, LLC, IPR Case No. 2020-00264, Paper 24 (PTAB May 22, 2020).  The PTAB found that the examiner “erred in a manner material to the patentability of the challenged claims” by overlooking certain aspects of the prior art references.

Puzhen Life USA, LLC, __ F.3d __ (Fed. Cir. May 19, 2020).  The CAFC found that substantial evidence supported the PTAB’s finding that a skilled artisan would have been motivated to combine the teachings of each prior art reference to arrive at the claimed invention, and that Patent Owner-Appellant’s challenge to the PTAB’s “real parties in interest” determination was not appealable.

Click-to-Call Techs., LP, No. 18-916, 590 U.S. ____ (2020).  According to the Court, 35 U.S.C. § 314(d)’s prohibition on appeal of IPR institution decisions and the Court’s decision in Cuozzo Speed Techs., LLC v. Lee, 136 S.Ct. 2131, 579 U.S. ___ (2016) were determinative.
 

On March 26, 2020, the Court of Appeals for the Federal Circuit (CAFC) affirmed the judgement of the Patent Trial and Appeal Board (Board) concerning claim construction.  Genentech, Inc. v.

On September 9, 2019, the Patent Trial and Appeal Board (“PTAB”) of the United States Patent and Trademark Office designated two decisions as precedential.  Infiltrator Water Technologies, LLC v.

United Technologies Corporation, IPR Case No. IPR2017-00491, Paper 9 (PTAB July 6, 2017) (designated: Sept. 9, 2019).  In Infiltrator Water, the PTAB held that a dismissal of a complaint without prejudice for lack of personal jurisdiction does not reset the one-year time bar for a petitioner to file a petition for inter partes review.  In General Electric, the PTAB denied institution where the patent owner disclaimed the challenged claims.

On August 29, 2019, the U.S. Patent and Trademark Office’s Patent Trial and Appeal Board (“PTAB”) designated as precedential a January 31, 2019 decision in Cisco Systems, Inc. v. Chrimar Systems, Inc., Case IPR2018-01511 (PTAB Jan. 31, 2019) (Paper 11).  The PTAB found that 35 U.S.C. § 315(a) bars a patent challenger from challenging a patent at the PTAB more than one year after filing a declaratory judgement (“DJ”) action in district court challenging the same patent, even if the patent challenger voluntarily withdrew the DJ action without prejudice.

Aug. 29, 2019).  The CAFC found that 35 U.S.C. § 314(d) bars it from reviewing the PTAB’s decision, even though the PTAB had previously issued a final written decision of patentability in each IPR.

On August 2, 2019, the Patent Trial and Appeal Board (“PTAB”) of the United States Patent and Trademark Office designated as precedential two Decisions on Institution.  Valve Corp. v. Elecs.

B Braun Melsungen AG, Case No. IPR2017-01586, Paper 8 (PTAB Dec. 15, 2017) (designated: Aug. 2, 2019).  In Valve, the PTAB held that General Plastic factor 1—concerning discretionary denials under 35 U.S.C. § 314(a) for “follow-on” petitions—applied to a joined petitioner.  In Becton, Dickinson, the PTAB delineated a list of factors to consider when determining whether to exercise its discretion to deny a petition under 35 U.S.C. § 325(d) where “the same or substantially the same prior art or arguments previously were presented to the Board.”

On July 10, 2019, the Court of Appeals for the Federal Circuit (CAFC) issued an opinion dismissing for lack of standing an appeal of a Patent Trial and Appeal Board (PTAB) inter partes review (IPR) decision finding certain patent claims not unpatentable.  General Electric Co. v.
