Short Summary
Samsung has filed an IPR petition seeking cancellation of 26 claims of U.S. Patent 11,443,344, which covers Bluetooth beacon‑based proximity services. The petition argues the claims are obvious over a combination of Watanabe, Ribaudo, and Behrens references.
Detailed Summary
Samsung Electronics Co., Ltd. and Samsung Electronics America, Inc. have petitioned the PTAB for inter‑partes review of U.S. Patent No. 11,443,344 owned by Secure Communication Technologies, LLC. The patent claims a method and system for using short‑range Bluetooth beacons together with a wide‑area network to exchange information between mobile devices. Samsung contends that the asserted claims are unpatentable under 35 U.S.C. §103 because a person of ordinary skill would have been motivated to combine the teachings of Watanabe (a Japanese beacon system), Ribaudo (a proximity‑determination system), and Behrens (a UID‑broadcast system) to arrive at the claimed invention. The petition requests cancellation of 26 claims (1‑10, 12‑16, 18‑19, and 22‑30) and provides detailed claim‑by‑claim mappings to the prior art.
