On October 15, 2025, four 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 (1-12) of U.S. Patent 10,305,638, owned and asserted by Wilus Institute of Standards & Technology, Inc., an entity of Good Day to Invent, Inc. The claims of the '638 patent are directed to access points configured to transmit a trigger frame with a particular structure to one or more stations to coordinate a multi-user uplink transmission from the station(s). The '638 patent has been asserted by Wilus against Askey, and it is related to patents that have been asserted against Samsung and HP Inc.
