Short Summary
Apple has filed an IPR petition challenging Apex Beam’s 2021 LTE beam‑switching patent. The petition relies on the Chen patent combined with 3GPP standards and the Dahlman textbook to argue obviousness of all twelve claims under §103.
Detailed Summary
In IPR2025-00896, Apple Inc. petitions the PTAB to invalidate claims 1‑12 of U.S. Patent No. 10,912,081, which cover methods and devices for wireless communication involving beam switching between a wide and narrow antenna beam within a time slot. Apple asserts that the Chen patent (U.S. Pat. No. 11,039,470) together with publicly available 3GPP Release 14 specifications, or alternatively with the Dahlman textbook on LTE, disclose every limitation of the challenged claims, rendering them obvious under 35 U.S.C. §103. The petition includes detailed claim charts, expert declaration, and references to prior IPR history, and requests that the Board institute review and cancel the claims.
