The U.S. Court of Appeals for the Federal Circuit (CAFC) ruled on Monday that the U.S. District Court for the Northern District of California erred in granting judgment as a matter of law (JMOL) that the relevant claims of Cyntec Company, Ltd.’s patents were not invalid as obvious and in denying Chilisin Electronics Corp.’s Daubert motion to exclude testimony from Cyntec’s damages expert. However, it affirmed the district court’s judgment of infringement.

On October 16, the U.S. Court of Appeals for the Federal Circuit (CAFC) issued a precedential decision in Corephotonics, Ltd. v. Apple Inc. affirming most of a final written decision by the Patent Trial and Appeal Board (PTAB) that invalidated dual-aperture camera system patents owned by Corephotonics. The Federal Circuit nixed the patent owner’s arguments that asserted prior art references were not analogous art but remanded to the PTAB for further explanation of its ruling, as the Board may have misconstrued the pertinent problem addressed by one reference.

In Sur-Replies filed late last week in inter partes review (IPR) proceedings, Urban Intel, Inc. told the Patent Trial and Appeal Board (PTAB) that threats made by ASSA ABLOY Global Solutions “to file IPR petitions and a declaratory judgment action unless granted a free license to three valuable patents,” among other allegations, “runs directly counter to the purpose and goals of the post-grant administrative challenge system.” The sur-replies are in response to petitioner’s replies filed earlier this month by hotel security company ASSA, addressing abuse of PTAB process allegations by Urban Intel. ASSA argued that the U.S. Patent and Trademark Office (USPTO) cannot enter sanctions against it because ASSA did not seek payment from Urban Intel’s exclusive licensee when it threatened to “rain down an avalanche of IPRs” if ASSA didn’t obtain a cost-free license to Urban Intel’s patents, according to the patent owner’s preliminary response.

It was a relatively average week for patent filings in the district court with 59 new complaints. New filings included multiple filings associated with high-volume plaintiffs such as Jeffrey Gross, Leigh Rothschild, as well as a slew of filings from Pueblo Nuevo in a banking campaign. Meanwhile, XR Communications settled three inter partes reviews (IPRs) and filed two new cases against wireless carriers.

The U.S. Court of Appeals for the Federal Circuit (CAFC) issued a precedential decision on Friday vacating-in-part a district court decision that granted SonicWall, Inc. summary judgment of invalidity based on a collateral estoppel decision that the CAFC had since vacated. Judge Bryson concurred in part and dissented in part, disagreeing with the majority’s analysis affirming the district court’s grant of summary judgment of noninfringement as to the claims of certain patents.

The U.S. Court of Appeals for the Federal Circuit (CAFC) on Tuesday, October 10, affirmed a district court’s dismissal at the pleading stage of a patent infringement, unjust enrichment and antitrust case against Qualcomm, Inc. Larry Golden sued Qualcomm in the U.S. District Court for the Northern District of California, alleging infringement of his patents on a system for locking, unlocking or disabling locks on vehicles upon detection of chemical or biological hazards, as well as antitrust and unjust enrichment claims.

On October 5, the U.S. Court of Appeals for the Federal Circuit (CAFC) heard oral arguments in VLSI Technology LLC v. Intel Corporation, an appeal following the massive $2.175 billion damages verdict handed by a Western Texas jury in March 2021 to VLSI for Intel’s infringement of two computer processor patents. The Federal Circuit judicial panel hearing the appeal drilled down on the sufficiency of VLSI’s expert testimony for establishing infringement under the doctrine of equivalents, as well as damages calculations that arguably relied upon data from non-infringing features of the accused technology.

Recent cases in the European Patent Office (EPO), the UK, and United States illustrate substantive differences between these jurisdictions as they continue to develop their inventive step/nonobviousness frameworks. In particular, the EPO and UK have recently provided guidance on a concept known as “plausibility,” i.e., whether the scope of the patent must be justified by the patentee’s technical contribution to the art in solving an identified problem. “If it is not plausible that the invention solves any technical problem then the patentee has made no technical contribution and the invention does not involve an inventive step.” Sandoz Limited v. Bristol-Meyers Squibb Holdings [2023] EWCA Civ 472. That standard, however, is quite dissimilar from the United States’ statutory standard of whether “the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious…”

On October 2, the Nobel Assembly at Karolinska Institutet announced that Hungarian-American biochemist Katalin Karikó and American immunologist Drew Weissman were awarded the 2023 Nobel Prize in Physiology or Medicine for their discoveries related to modified messenger ribonucleic acid (mRNA) for use in vaccines. A critical part of the world’s response to the COVID-19 pandemic, mRNA vaccines were not an effective option until the pioneering work of these two scientists, one of whom faced considerable rejection while laying the foundation that answered one of the world’s greatest public health crises.

The U.S. Supreme Court today denied the petition for certiorari brought by CareDX, Inc. in May asking it to review a 2022 decision holding certain claims of its patents directed to detection levels of donor cell-free DNA (cfDNA) in the blood of an organ transplant patient patent ineligible. Justice Bret Kavanaugh would have granted the petition, according to the Order List.

Digital video company, DivX, scored a win in a Brazilian court after a judge ratified its expert report and enforced a previously-granted preliminary injunction against Netflix. DivX sued Netflix for infringement of its Patent No. PI 0506163-6, which is directed to a “deblocking” tool implemented in High Efficiency Video Coding (HEVC)-encoded files. According to DivX, Netflix’s streaming in HEVC infringes the patent.

Twenty-five intellectual property luminaries sent a letter today to several members of Congress asking them to beware of misleading and inaccurate assertions by “activists and academics” that government price controls on drugs will lead to lower costs for consumers. The letter was sent to Senators Bernie Sanders (I-VT) and Bill Cassidy (R-LA), Chairman and Ranking Member, respectively, of the Senate Committee on Health, Education, Labor & Pensions; and Representatives Jason Smith (R-MO) and Richard Neal (D-MA), Chairman and Ranking Member, respectively, of the House Committee on Ways and Means.

The U.S. Patent and Trademark Office (USPTO) has extended the deadline for comments on its joint request for comments (RFC) with the International Trade Administration (ITA) and the National Institute for Standards and Technology (NIST) on the agencies’ collaboration initiative concerning standards and intellectual property. In a Federal Register Notice (FRN) published today, the USPTO announced the new deadline will be November 6, 2023. The original deadline was September 29.

On September 25, independent inventor Carolyn Hafeman filed a reply brief  arguing that efforts by consumer tech giant LG Electronics to prejudice Hafeman’s legal claims in front of a Western Texas jury require the court to grant a new patent infringement trial in the case. Among other things, Hafeman contends that LG’s invalidity arguments at trial violated LG’s own Sotera stipulation filed in inter partes review (IPR) proceedings brought by LG suppliers Google and Microsoft to challenge the validity of Hafeman’s patent claims asserted against LG.

The U.S. Court of Appeals for the Federal Circuit (CAFC) today denied a petition for writ of mandamus filed by Realtek Semiconductor Corporation seeking to direct the International Trade Commission (ITC) to vacate its ruling granting Advanced Micro Devices, Inc. (AMD)’s motion to strike Realtek’s witness from testifying at an upcoming evidentiary hearing.
