Short Summary
Samsung challenged Wilus's wireless patent claims based on obviousness in view of prior art standards and publications. The PTAB institution decision found a reasonable likelihood that the claims are unpatentable, specifically citing combinations of Bharadwaj and Sun. This sets up a significant trial over HE WLAN technology.
Detailed Summary
Samsung Electronics Co., Ltd. challenged nine claims of Wilus Institute of Standards and Technology Inc.'s patent (11159210) at the PTAB under 35 U.S.C. § 103, alleging obviousness. The Board determined there was a reasonable likelihood that Petitioner would prevail, particularly regarding Ground 2, which combines Bharadwaj and Sun to teach all limitations of the claims. The analysis centered on HE MU PPDU decoding signaling fields in High Efficiency Wireless Local Area Networks (WLAN), with the Board noting the public accessibility of draft standards like 802.11ax_D1.0. Given the institution decision, the case moves forward to trial proceedings.
