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.

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.

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.

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.

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.

The Federal Circuit reversed a district court’s summary judgment finding written description inadequacy for Nevro’s spinal cord stimulation patents, holding that the specification’s disclosure of the claimed frequency ranges combined with paresthesia-free stimulation raised genuine issues of material fact about whether a skilled artisan would have recognized the inventor’s possession of the full claimed range.
