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.

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.

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).

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.

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.

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.

Apple Inc., __ F.4th __ (Fed. Cir. Jan. 27, 2022).

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, 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.

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).

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 September 10, 2021, the Court of Appeals for the Federal Circuit (CAFC) issued an order denying a petition for a writ of mandamus to the United States District Court for the Western District of Texas, Nos. 6:20-cv-00952-ADA, 6:20-cv-00953-ADA, 6:20-cv-00956-ADA, 6:20-cv-00957-ADA, and 6:20-cv-00958-ADA, Judge Alan D.

Sept. 10, 2021).  Judge Andrews held that certain claims of the asserted patent containing “translator device…” limitations were invalid as indefinite under 35 U.S.C. § 112 ¶ 6 because they failed to disclose corresponding structure for the claimed function.

Intex Recreation Corp., __ F.3d __ (Fed. Cir. Sept. 9, 2021)

On September 1, 2021, the United States Court of Appeals for the Federal Circuit (CAFC) found that the District Court for the Central District of California erred in awarding damages for sales of infringing products prior to the date that the infringer received actual notice of infringement for failure to prove its compliance with the patent marking statute.  Lubby Holdings LLC v.

Sony Corporation of America, ___ F.3d ___ (Fed. Cir. July 13, 2021).  The CAFC clarified that while a plaintiff need not plead infringement on an element-by-element basis, reciting claim elements and merely concluding that the accused products have those elements is insufficient.
