Short Summary
Samsung’s petition to invalidate Headwater Research’s 9,271,184 patent on obviousness grounds was denied. The Board concluded the prior art did not teach the specific blocking step required by the claims, failing the reasonable‑likelihood test.
Detailed Summary
In IPR2023-01362, Samsung Electronics Co., Ltd. sought to invalidate claims 1 and 7‑9 of Headwater Research LLC’s U.S. Patent No. 9,271,184, alleging obviousness over prior art references Rao, Oestvall, Freund, and Montemurro. The Patent Trial and Appeal Board found that the cited references did not disclose the patent’s distinctive pre‑connection blocking of Internet service access requests, and that Samsung’s combination failed to demonstrate a teaching of this step. Accordingly, Samsung did not meet the reasonable likelihood of success requirement under 35 U.S.C. § 314(a), and the petition was denied with no trial instituted.
