Detailed Summary
In Petition for Inter Partes Review IPR2026-00066, Taiwan Semiconductor Manufacturing Company Ltd. (TSMC) and Apple Inc. challenge U.S. Patent No. 11,538,763 owned by MYW Semitech, LLC. The petition alleges that claims 1‑23 are unpatentable under 35 U.S.C. § 103 as obvious in view of a suite of prior‑art references, including Sundaram, Lin‑191, Lin‑863, Lin‑691, Shenoy and Yu. The challengers argue that the patent’s claimed ranges lack criticality and that a person of ordinary skill would have been motivated to combine the teachings of the references, rendering the invention obvious. No claim construction is required because the prior art falls within the scope of the claims under any reasonable interpretation. The petition is pending before the PTAB.
