On July 27, 2026, the U.S. Court of Appeals for the Federal Circuit (CAFC) issued a precedential decision in Board of Regents of the University of Texas System v. Boston Scientific Corp., reversing a jury trial verdict that found Boston Scientific Corporation (BSC) liable for infringing a Board of Regents of the University of Texas System (UT) owned patent for drug-releasing biodegradable fiber implants. In the reversal, the CAFC found that the '296 patent was anticipated by U.S. Patent No. 5,364,627 (the '627 patent, “Song”) and that BSC was entitled to judgment as a matter of law (JMOL) on both anticipation and non-infringement, returning the $49.4 million jury awarded damages to BSC.<...

In our January Newsletter (here) we reported on the non-precedential Federal Circuit decision in Daiichi Sankyo Co. v. Seagen Inc., Fed. Cir. Dec 02, 2025, appeal 2023-2424, holding that Seagen’s U.S. Patent 10,808,039 (‘039) was invalid for lack of written description and enablement, over turning a jury verdict and JMOL to the contrary. This was the second time in a two-week period that the Court had overturned jury verdicts in favor of the patentee on written description. As the Court recognized in the earlier decision Duke Univ. et al. v Sandoz, Inc., 160 F.4th 1305 (2025) “a district court’s refusal to grant judgment as a matter of law may be reversed only if the evidence is such that without weighing the credibility of the witnesses the only reasonable conclusion is in the moving party’s favor.” This is a high burden to meet.<...

On February 20, 2026, the U.S. Court of Appeals for the Federal Circuit (CAFC) issued a decision regarding recombinant DNA subject-matter eligibility, reversing a decision by the United States District Court for the District of Delaware in REGENXBIO, Inc. v. Sarepta Therapeutics. The district court had previously ruled claims of U.S. Patent No. 10,526,617 (the ‘617 patent) covering a cultured host cell containing a recombinant nucleic acid molecule patent ineligible under 35 U.S.C. § 101 during a patent infringement suit in which both parties moved for summary judgment of patent eligibility under 35 U.S.C. § 101. The district court agreed with Sarepta and held the claims ineligible under § 101 as directed to a natural phenomenon. The CAFC held the claims as not being directed to a natural phenomenon and reversed the district court’s decision, remanding the case for further proceedings.<... Read more

An obviousness rejection was recently reversed by the Patent Trial and Appeal Board (PTAB) by the panel of Administrative Patent Judges (APJs) authored by Debra L. Dennett, and further including Jeffrey W. Abraham and Avelyn M. Ross in U.S. Appl. No. 17/395,422 (the 422 Application). The PTAB reversed the obviousness finding of examiner Justin Fischer, supported by Supervisory Patent Examiner (SPE) Katelyn W. Smith, and Quality Assurance Specialist (TQAS) Colleen P. Dunn, on the alleged obviousness of the claims over a combination of three to five references, three of which were the applicant-appellant’s own prior art. The main claim on appeal recited<...

On June 30, the U.S. Court of Appeals for the Federal Circuit (CAFC) issued a precedential decision regarding transitional phrase claim construction, reversing the decision of the Patent Trial and Appeal Board (PTAB) in Eye Therapies, LLC. v. Slayback Pharma, LLC. The PTAB had previously ruled the claims of U.S. Patent No. 8,293,742 (the ‘742 patent) unpatentable as obvious in a inter partes review brought by Slayback. During the inter partes review, the parties had disagreed on the construction of the transitional phrase “consisting essentially of” in the ‘742 patent. The Court found that the Board had incorrectly applied the conventional open construction of the transitional phrase, which was at odds with the prosecution record. This demonstrates how prosecution history can alter a phrase’s typical meaning.<... Read more
