Short Summary
Nintendo has filed an IPR petition challenging claims 2 and 3 of Resonant Systems’ linear vibration module patent, asserting obviousness over multiple prior‑art references and seeking cancellation of the claims.
Detailed Summary
In Petition IPR2025-01098, Nintendo Co., Ltd. and Nintendo of America, Inc. request inter partes review of claims 2 and 3 of U.S. Patent No. 8,860,337 owned by Resonant Systems, Inc. The petition alleges that the claims are unpatentable under 35 U.S.C. §103 as obvious in view of a combination of prior‑art references—including Wakuda, Ramsay, Rossi, Aldrich, Fukumoto, Saiki, and Masahiko—each of which teaches the individual claim limitations. Nintendo also argues that the PTAB has already instituted a related IPR on the same claims, invoking both statutory and common‑law estoppel to preclude the patent owner from contesting the same limitations. The petition further contends that the disputed terms are means‑plus‑function limitations, for which the prior art provides the requisite structure. The case is pending institution.
