EMC Corp. v. Pure Storage — Federal Circuit on Obviousness and Secondary Considerations in Data Storage Patents

The Federal Circuit affirmed the PTAB’s invalidation of EMC’s data storage system patents on obviousness grounds — holding that the PTAB properly weighed secondary considerations of non-obviousness including commercial success and industry praise, but found them insufficient to overcome the strong prima facie case of obviousness established by the prior art.

Biogen International GmbH v. Banner Life Sciences LLC — Federal Circuit Holds Patent Term Extension Covers Only Approved Active Ingredient, Not Its Metabolite

The Federal Circuit held that a patent term extension under the Hatch-Waxman Act covers only the active ingredient actually approved by the FDA—and its salts and esters—but does not extend to a metabolite of that ingredient, even if the metabolite is what is pharmacologically active in the body.

Supreme Court, Utility Patent

Thryv v. Click-to-Call Technologies — Supreme Court Extends Non-Reviewability to IPR Time-Bar Determinations

The Supreme Court held 7-2 that § 314(d)’s bar on judicial review of IPR institution decisions extends to determinations about the § 315(b) one-year time bar — meaning courts cannot review whether the PTAB incorrectly concluded that a petition was timely filed within the statutory one-year period after service of a complaint alleging infringement.

The Federal Circuit applied the Kessler doctrine — a nineteenth-century rule of preclusion in patent law — to bar PersonalWeb from relitigating patent infringement claims against Amazon Web Services customers after PersonalWeb had previously lost in a suit against Amazon directly, holding that customers of an adjudicated non-infringer are protected from subsequent patent suits on the same technology.

American Axle v. Neapco Holdings — Federal Circuit Holds Driveshaft Manufacturing Method Claims Ineligible Under Hooke’s Law

The Federal Circuit held that patent claims directed to manufacturing driveshaft liners that “attenuate” vibrations were invalid under § 101 because they were simply an instruction to apply Hooke’s law — a natural law — without specifying how to do so, triggering a sharp dissent warning of § 101 overreach.

Wi-LAN v. Apple — Federal Circuit Addresses FRAND Comparable License Analysis and Royalty Apportionment

IOENGINE v. PayPal Holdings — Federal Circuit Addresses IPR Estoppel and Non-Patent Prior Art Grounds

The Federal Circuit clarified the scope of IPR estoppel under § 315(e)(2), holding that IPR estoppel applies only to grounds based on patents or printed publications — the types of prior art available in IPR — and does not bar district court invalidity challenges based on prior art that could not have been raised in IPR, such as prior public use or on-sale evidence.

Cellspin Soft v. Fitbit — Federal Circuit Applies Berkheimer to Deny Motion to Dismiss on § 101 Grounds

The Federal Circuit reversed a district court’s dismissal of patent claims as ineligible under § 101, applying Berkheimer to hold that well-pleaded factual allegations about how the claimed invention was an unconventional advance must be accepted as true at the 12(b)(6) stage — limiting early § 101 dispositive motions where patents allege specific technical improvements.

PTAB, Utility Patent

Xilinx v. Analog Devices — Federal Circuit on IPR Petition Grounds and Institution of Partial Review

The Federal Circuit addressed the PTAB’s discretionary authority under § 314(a) to deny IPR petitions based on factors including the stage of parallel district court litigation and the efficiency of institution — affirming the PTAB’s broad discretion in institution decisions and its authority to consider the NHK-Fintiv framework for balancing IPR efficiency against parallel litigation.
