On October 14, 2025, seven weeks after Unified filed an ex parte reexamination, the Central Reexamination Unit (CRU) granted Unified’s request, finding substantial new questions of patentability on the challenged claims of U.S. Patent 10,931,396, owned and asserted by Wilus Institute of Standards & Technology, Inc., an entity of Good Day to Invent, Inc.

The '396 patent is generally directed wireless terminals that receive an A-MPDU (aggregated MAC protocol data unit) with a particular delimiter field that directs the device on the specific format of the response frame to transmit back. It has been asserted against Askey and its routers, which are Wi-Fi 6 (802.11ax) enabled devices. The '396 patent is related to U.S. Patent 11,664,926, which has been asserted against Samsung, HP Inc., and Askey.
