IPR2025-00495

Detailed Summary

In an expert declaration supporting Four Batons Wireless, LLC, Dr. Aviel D. Rubin systematically refutes Samsung Electronics’ arguments that the ’671 patent claims are obvious over the cited prior art. He examines each ground—Sood alone, Sood with the Aboba RFC, Sood with the Lee application, and the three‑reference combination—demonstrating missing claim elements, lack of motivation, and incompatibilities with standards such as IEEE 802.11i. Rubin concludes that none of the challenged claims satisfy the obviousness test under 35 U.S.C. § 103, indicating that the petition is unlikely to succeed. The declaration underscores the robustness of the ’671 patent’s claim set against the asserted prior art.
