CAFC Delivers Blow to Apple in Appeal of PTAB Disputes with Smart Mobile

The U.S. Court of Appeals for the Federal Circuit (CAFC) issued two decisions today in related appeals arising from inter partes review (IPR) proceedings between Apple Inc. and Smart Mobile Technologies LLC. In the case, Apple Inc. v. Smart Mobile Technologies LLC, the CAFC affirmed a Patent Trial and Appeal Board (PTAB) determination that Apple failed to prove certain claims of two Smart Mobile patents unpatentable as obvious, while vacating and remanding a separate portion of the same judgment that had found other claims obvious. In the companion appeal, the CAFC affirmed the PTAB’s decision rejecting Apple’s obviousness challenge to a third related patent. Circuit Judge Stark authored both opinions for a panel that included Circuit Judges Reyna and Hughes.

Ninth Circuit Rejects Boeing’s Bid to Rehear Appeal of Trade Secret Loss

The U.S. Court of Appeals for the Ninth Circuit yesterday rejected Boeing’s bid to revisit its August 2025 ruling in favor of electric-aircraft startup Zunum Aero, holding that Boeing’s patent-inventorship counterclaims did not strip the Ninth Circuit of jurisdiction over the trade secret dispute. The Ninth Circuit panel denied Boeing’s petition for panel rehearing after concluding that its patent counterclaims were “permissive” rather than “compulsory”, and therefore not subject to the exclusive jurisdiction of the U.S. Court of Appeals for the Federal Circuit.

Not Every AI Output Belongs in an IDS

An AI interaction can give rise to a Rule 56 disclosure obligation. Not because AI was involved, but because of the information the interaction put before you. The U.S. Patent and Trademark Office (USPTO) has already drawn that line. Its April 2024 guidance says there is no general obligation to disclose that an AI tool was used; the duty is implicated when the use rises to the level of materiality under Rule 56(b). The trigger is materiality, not AI.

Why High-Quality U.S. Patent Specifications Face Fatal Failures in China

In 2025, a patent dispute between Chinese companies in the camera-module space drew close attention across the industry — SUNNY v. AAC [Patent Reexamination and Invalidation Department Decision No. 566288, et al.]. The case ended with 11 patents invalidated, four of them in their entirety. There was a single reason: the claims were not supported by the specification.

Federal Circuit Vacates in Part, Affirms in Part PTAB Ruling in Cisco IPR

The U.S. Court of Appeals for the Federal Circuit (CAFC) issued a decision today in Zilkr Cloud Technologies, LLC v. Cisco Systems, Inc., vacating in part and affirming in part a Patent Trial and Appeal Board (PTAB) final written decision.

The opinion was authored by Chief Judge Moore.

PTAB Designates Stakeholder-Nominated Ruling on Flexible Markush Analysis as Informative

Yesterday, the U.S. Patent and Trademark Office (USPTO) announced that the agency had designated as informative a Patent Trial and Appeal Board (PTAB) decision in an ex parte appeal reversing an examiner’s rejection of patent claims directed to the isolation and detection of microRNA (miRNA) to determine a patient’s risk of radiation exposure for improper Markush groupings. Drawing primarily upon case law from the predecessor to the U.S. Court of Appeals to the Federal Circuit, the informative designation is notable for its alignment with recent Federal Circuit case law encouraging flexibility in Markush grouping analyses.

Commenters Split on USPTO Proposal to Require RPI Disclosure for Reexams

Following the U.S. Patent and Trademark Office’s (USPTO’s) July 2026 proposal to require third-party requesters for ex parte reexamination (EPR) to identify all real parties in interest (RPIs), the 26 comments submitted to the Office reveal a sharp divide among the patent owners, tech companies, industry associations and individuals who weighed in.
