Samsung has filed an IPR petition challenging 21 claims of GenghisComm’s ’386 OFDM patent, asserting anticipation and obviousness over Shattil‑537, Galda, Brüninghaus and Dowling.
Detailed Summary
In Petition IPR2025‑00899, Samsung Electronics Co., Ltd. and its affiliate Samsung Electronics America, Inc. seek inter partes review of 21 claims of U.S. Patent No. 11,431,386 owned by GenghisComm Holdings LLC. The challenger contends that the claims are either anticipated by the Shattil‑537 international publication or rendered obvious by combinations of prior art references, including Shattil‑537, Galda, Brüninghaus, and Dowling. Detailed analyses map each claim limitation to specific teachings, arguing that a person of ordinary skill would have been motivated to combine these teachings to achieve the claimed subject matter. The petition includes expert declarations and a comprehensive exhibit list, and it reserves the right to address discretionary denial arguments later.
