Short Summary
Apple has filed a petition for inter partes review of Cobblestone Wireless’s ’347 patent, asserting that its claims are obvious over Hardacker, Medbo, and Wallace prior art. The petition seeks institution of the IPR and argues that discretionary denial is unwarranted.
Detailed Summary
In Petition IPR2025-01496, Apple Inc. challenges U.S. Patent No. 8,889,347 owned by Cobblestone Wireless, LLC, asserting that the patent’s claims covering user‑focusing pre‑distortion techniques in wireless communication systems are unpatentable under 35 U.S.C. §103. The petition identifies four grounds of obviousness, each relying on one or more prior‑art references—Hardacker (U.S. Patent Pub. 2010/0159855A1), Medbo (U.S. Patent Pub. 2014/0010274A1), and Wallace (U.S. Patent No. 6,473,467)—to show that each claim element is taught or would have been obvious to a person of ordinary skill. Apple also argues that the Board should not exercise discretionary denial and requests that the IPR be instituted. The petition references related IPRs and district‑court actions involving the same patent.
