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. Am. Nat’l Mfg. Inc. v. Sleep No. Corp., Nos. 2021-1321, 1323, 1379, 1382, (Fed. Cir. Nov. 14, 2022). 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 November 8, 2022, in a precedential order, the Court of Appeals for the Federal Circuit (CAFC) granted Apple Inc.’s petition for a writ of mandamus vacating the scheduling order of the District Court for the Western District of Texas and directing that court to stay all proceedings on the merits and resolve Apple’s pending motion to transfer.  While the CAFC did not decide the extent to which merits discovery may proceed while issues of venue and venue discovery are still pending, it nevertheless ruled that transfer decisions must “proceed expeditiously” as “the first order of business.”  In re Apple Inc., No. 2022-162 (Fed. Cir. Nov. 8, 2022).
 

On November 1, 2022, the United States Court of Appeals for the Federal Circuit (“CAFC”) issued an opinion reversing-in-part, vacating-in-part, and remanding a summary judgment decision by the United States District Court for the Southern District of California, Judge Cathy Ann Bencivengo, finding asserted claims from a family of related patents indefinite and thus invalid. Finjan LLC, Inc. v. ESET, LLC, No. 2021-2093 (Fed. Cir. Nov. 1, 2022). The CAFC held, inter alia, that the district court’s construction of the term “Downloadable,” appearing in all asserted claims, was improperly restricted to the narrowest of competing definitions provided in the patent family.

On October 19, 2022, the Federal Circuit, on a petition for writ of mandamus, vacated and remanded an order by Judge Mazzant of the Eastern District of Texas (EDTX) denying FedEx Corporate Services, Inc.’s motion to transfer the case to the Western District of Tennessee (WDTN). In re FedEx Corp. Servs., Inc., No. 2022-156 (Fed. Cir. Oct. 19, 2022). The Court found that the district court had erred in its analysis of the local interest factor and had failed to provide a sufficient explanation regarding witness-related factors, the latter of which left the Court “unable to effectively conduct mandamus review on the present record.”

On October 17, 2022, the United States Court of Appeals for the Federal Circuit (CAFC) affirmed the ruling of the Western District of Washington (W.D. Wash.) that patents directed to abstract ideas absent a transformative inventive concept are not deemed to be patentable subject matter under 35 U.S.C. § 101. IBM v. Zillow Grp., Inc., No. 2021-2350, -- F.4th -- (Fed. Cir. Oct. 17, 2022).

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).

On September 30, 2022, the United States Court of Appeals for the Federal Circuit (CAFC) denied a petition for writ of mandamus challenging, inter alia, the denial of a motion to dismiss for improper venue under 28 U.S.C. § 1400(b) by the United States District Court for the Western District of Texas (W.D. Tex.).  In re Monolithic Power Systems, Inc., No. 2022-153, -- F.4th --  (Fed. Cir. Sept. 30, 2022).  Noting that mandamus review is not ordinarily available for rulings on improper venue motions, a panel majority found that the district court’s fact-specific ruling does not involve the type of broad, fundamental and recurring legal question or usurpation of judicial power that warrants the extraordinary remedy of mandamus.

On September 16, 2022, Judge Albright of the Western District of Texas denied three related Defendants’ motion to transfer venue, under 28 U.S.C. § 1404(a), from the Western District of Texas to the Northern District of California, on the grounds that venue in California would be improper for one of the moving Defendants, a holding company.  MOV-ology LLC v. BigCommerce Holdings, Inc. et al, Case No. 6-22-cv-00084 (WDTX).

On September 19, 2022, Magistrate Judge Payne of the U.S. District Court for the Eastern District of Texas issued a Report and Recommendation regarding certain foreign defendants’ motion to dismiss for failure to perfect service of process.  Arigna Tech. Ltd. v. Nissan Motor Co., No. 2:22-cv-00126-JRG-RSP (E.D. Tex. Sept. 19, 2022).  Judge Payne recommended denying the motion, finding that service on an agent of the foreign defendants’ U.S. subsidiary was proper.

On September 7, 2022, the Court of Appeals for the Federal Circuit (“CAFC”) affirmed a district court dismissal under the duplicative-litigation doctrine.  Under the duplicative-litigation doctrine, plaintiffs cannot “maintain two separate actions involving the same subject matter at the same time in the same court … against the same defendant.”  Arendi S.A.R.L. v. LG Elecs. Inc., No. 2021-1967, 2022 BL 313997 (Fed. Cir. Sept. 7, 2022).

On August 31, 2022, the Court of Appeals for the Federal Circuit (CAFC) affirmed a determination of non-infringement by the International Trade Commission (ITC).  Although the CAFC disagreed with the ITC as to whether the claims were directed towards capability, the CAFC nevertheless affirmed the finding of non-infringement because the capability had not been proven.  INVT SPE LLC v. Int’l Trade Comm’n, No. 2020-1903, -- F.4th -- (Fed. Cir. Aug. 31, 2022).

On August 29, 2022, the United States Court of Appeals for the Federal Circuit (“CAFC”) issued an opinion in a consolidated appeal relating to two inter partes reexamination (“IPR”) decisions from the Patent Trial and Appeal Board (“PTAB”) finding all challenged claims of United States Patent 6,393,096 unpatentable.  Best Medical Int’l., Inc. v. 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.

On August 3, 2022, the Judicial Panel on Multidistrict Litigation (“JPML”) ordered that four patent cases—two patent infringement actions in the United States District Court for the Eastern District of Texas and one declaratory judgment action each in the United States District Courts for the Southern District of New York and the Northern District of Texas—be consolidated in the Eastern District of Texas and that the Honorable J. Rodney Gilstrap shall preside over the multidistrict district litigation.  In re Taasera Licensing, LLC, Pat. Litig., No. MDL 3042 (J.P.M.L.).

On July 27, 2022, the United States Court of Appeals for the Federal Circuit (CAFC) affirmed a decision by the United States District Court for the Central District of California (C.D. Cal.) awarding fees incurred by defendant for two proceedings under its inherent equitable powers and denying fees incurred in earlier, related proceedings.  Realtime Adaptive Streaming LLC v. Netflix, Inc., Nos. 2021-1484, 2021-1485, 2021-1518, 2021-1519 (Fed. Cir. July 27, 2022).  The CAFC found that the C.D. Cal. did not abuse its discretion in granting attorney’s fees incurred in the C.D. Cal. as a result of the patentee’s improper forum shopping to avoid an adverse ruling, but denying fees incurred in earlier district court and inter partes review (IPR) proceedings because there was no evidence that plaintiff knew or should have known at that time that its claims were weak.

On July 18, 2022, the United States Court of Appeals for the Federal Circuit (“CAFC”) issued a precedential opinion affirming a judgment by the United States District Court for the Eastern District of Delaware (Chief Judge Colm F. Connolly) that plaintiff's organ transplant diagnosis patents encompassed unpatentable subject matter.  CareDx, Inc. v. Natera, Inc., __ F.3d __ (Fed. Cir. July 18, 2022).  In its decision, the CAFC held that the district court correctly found the asserted claims to be directed to a natural phenomenon and that the claimed combination of steps is not inventive.

On July 14, 2022, the Court of Appeals for the Federal Circuit (CAFC) sanctioned plaintiff-appellant Pop Top Corp. for the filing of a frivolous appeal, granting defendant-appellee Rakuten Kobo Inc. $107,748 in attorney’s fees and doubled costs.  Pop Top Corp. v.

LLC v. Kingston Tech. Co., Inc., No. 2021-1834 (Fed. Cir. June 3, 2022).  The CAFC found that the CDCA properly corrected an obvious minor clerical error in the asserted claims and held that defendant’s reliance on such error was not a defense to willful infringement.

On May 26, 2022, Judge Joan M. Azrack of the United States District Court for the Eastern District of New York granted defendants’ motion to dismiss or transfer for improper venue on account of plaintiffs’ failure to plead sufficient venue-related allegations, and further denied plaintiffs’ request for venue discovery.  UI Technologies, Inc., et al. v.

Rodney Gilstrap, directing the district court to transfer patent cases to the United States District Court for the Northern District of California.  In re Google LLC, __ F.3d __ (Fed. Cir. May 23, 2022).  In its order, the CAFC held that the district court abused its discretion in failing to weigh the local interest factor in favor of transferee forum and erred in its analysis of other factors.

On May 20, 2022, the U.S. Court of Appeals for the Federal Circuit (“CAFC”) vacated a final written decision from the U.S. Patent Trial and Appeal Board (“PTAB”), remanding for the PTAB to resolve a factual dispute over inventorship that it had left unaddressed.  Google LLC v.

On April 29, 2022, the U.S. Court of Appeals for the Federal Circuit (“CAFC”) vacated and remanded the final written decision of the Patent Trial and Appeal Board (“PTAB”), which found that the Petitioner, Auris Health, Inc. (“Auris”), had failed to demonstrate that the challenged claims were unpatentable as obvious based on evidence of general skepticism about the field of invention.  Auris Health, Inc. v. Intuitive Surgical Operations, __ F.4th __ (Fed. Cir. April 29, 2022).

On April 7, 2022, Judge Selna of the United States District Court for the Central District of California (CDCA) granted plaintiff’s motion for a presumption of patent infringement and to shift the burden pursuant to 35 U.S.C. § 295.  PureCircle USA Inc. et al v. SweeGen, Inc. et al, 8-18-cv-01679.

Zipit Wireless, Inc., No. 2021-1760 (Fed. Cir. Apr. 18, 2022).  The CAFC found that the NDCA erred in applying a bright-line rule that patent infringement notice letters can never form the basis for personal jurisdiction.

On April 4, 2022, the Court of Appeals for the Federal Circuit (CAFC) issued a precedential opinion vacating claim constructions ordered by the United States District Court for the District of Massachusetts in No. 1:17-cv-12375-IT, Judge Indira Talwani.  Littelfuse, Inc. v.  Mersen USA EP Corp., __ F.3d __ (Fed. Cir. April 4, 2022).  In its order, the CAFC concluded that the district court’s constructions incorrectly limited claim scope to a preferred embodiment and rendered certain dependent claims superfluous.

On April 1, 2022, the Court of Appeals for the Federal Circuit (CAFC) reversed a district court’s claim construction and corresponding summary judgement of non-infringement decisions.  The lower court had improperly relied on extrinsic evidence to determine what had been disclaimed by the applicant during prosecution.  Genuine Enabling Tech. v. Nintendo Co., Ltd., No. 2020-2167 (Fed. Cir. Apr. 1, 2022).

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.

(“Repifi”) for failure to state a claim upon which relief can be granted, because the asserted claims are ineligible for patent protection under 35 U.S.C. § 101. Repifi Vendor Logistics, Inc. v.

SZ DJI Technology Co., Ltd., No. 6:20-cv-00073-ADA, Dkt. No. 173 (W.D. Tex. Mar. 3, 2022).  The Court found the expert’s initial, timely-served report used the wrong parties in his hypothetical negotiation analysis and, for that reason, could not withstand defendant’s Daubert challenge.  On the other hand, the expert’s “supplemental” report re-doing his analysis with the correct parties was untimely and thus stricken.

On February 25, 2022, the United States District Court for the Western District of Texas (WDTX) filed a redacted copy of its February 11, 2022 order denying a motion to dismiss for improper venue.  WSOU Investments LLC d/b/a Brazos Licensing & Dev. v.

Feb. 25, 2022).  The WDTX, applying a more relaxed burden for purposes of establishing venue through an alter ego theory, found that defendant had a regular and established place of business in the District through the office of its wholly-owned subsidiary.

On February 23, 2022, Judge Payne of the United States District Court for the Eastern District of Texas (“EDTX”) granted plaintiff’s motion to sever defendant’s counterclaims asserting patent infringement of claims directed to technologies that are distinct from those at-issue in plaintiff’s offensive case.  United Services Automobile Association v.

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).

On January 27, 2022, the Court of Appeals for the Federal Circuit (“CAFC”) reversed the judgment of the United States District Court for the Northern District of California finding certain claims invalid on the ground of claim indefiniteness under 35 U.S.C. § 112(b), because the district court erred by applying an incorrect legal standard.  Nature Simulation Sys. Inc. v. Autodesk, Inc., __ F.4th __ (Fed. Cir. Jan. 27, 2022).

On January 19, 2022, the United States Court of Appeals for the Federal Circuit (CAFC) granted mandamus directing the United States District Court for the Eastern District of Texas (EDTX) to transfer the case against petitioner to the United States District Court for the Northern District of California (NDCA).  In re Netflix, Inc., No. 2022-110 (Fed. Cir. Jan. 19, 2022).  The CAFC found that Chief Judge Rodney Gilstrap’s denial of transfer under 28 U.S.C. 1404(a) was a clear abuse of discretion.

On January 6, 2022, Chief Judge Gilstrap of the United States District Court for the Eastern District of Texas denied a motion to stay pending ex parte reexamination (“EPR”) of the patent asserted in the litigation, and found that defendant was relying on the EPR as part of a strategy of “examiner shopping.”  Longhorn HD LLC v. NetScout Systems, Inc., 2-20-cv-00349.

On January 3, 2022, the Court of Appeals for the Federal Circuit (CAFC) affirmed the district court’s finding that a patent claim does not fail the written description requirement merely because the specification fails to explicitly state a negative claim limitation.  Novartis Pharmaceuticals v.

On December 8, 2021, Judge Albright of the U.S. District Court for the Western District of Texas issued a sealed opinion granting the defendants’ motion to transfer venue to the Northern District of Georgia.  Lynk Labs, Inc v. Home Depot USA, Inc., No. 6:21-cv-00097-ADA (W.D. Tex.

​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.

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 November 15, 2021, the United States District Court for the Eastern District of Texas found that the asserted claims directed at data collection, storage, management, and access were abstract, but refused to dismiss the claims under the second step in the Alice analysis. Gravel Rating Systems, LLC v. McAfee, LLC, Case No. 4:21-CV-259-ALM.

Mylan Pharmaceuticals Inc., __ F.3d __ (Fed. Cir. Nov. 5, 2021).  In its order, the CAFC affirmed that plaintiff had not established that the domestic defendants committed acts of infringement in New Jersey or had regular and established places of business there and had not sufficiently pleaded a claim against the foreign parent defendant.

On November 04, 2021, the Court of Appeals for the Federal Circuit (CAFC) reversed the Patent Trial and Appeal Board’s (PTAB’s) holding that a patent claim was obvious, rejecting both the PTAB’s finding that the prior art disclosed all claim limitations and the PTAB’s finding that the combination of references would result in a reasonable expectation of success. University of Strathclyde v. Clear-Vu Lighting LLC, No. 2020-2243 (Fed. Cir. Nov. 04, 2021).
