Short Summary
Apple Inc. filed an IPR petition challenging all 30 claims of U.S. Patent 11,991,601, asserting that the claims are obvious over a combination of four prior‑art references covering wireless messaging. The petition seeks institution of the review and cancellation of the claims.
Detailed Summary
In Petition IPR2026‑00107, Apple Inc. challenges the validity of claims 1‑30 of U.S. Patent No. 11,991,601, titled “Wireless Messaging Method and Server.” The challenger alleges that the claims are unpatentable under 35 U.S.C. § 103 because a person of ordinary skill in the art would have found it obvious to combine teachings from four prior‑art publications—Horvath, Tsampalis, Kansal, and Quon—to achieve the patented method of selectively transmitting messages over packet‑switched or circuit‑switched networks, determining recipient capabilities, and inviting non‑subscribers. Apple’s petition includes expert testimony from Dr. Patrick Traynor and requests that the PTAB institute the IPR and cancel all challenged claims.
