On August 29, 2025, Unified filed two ex parte reexamination proceedings against U.S. Patent 10,820,233 and 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 '233 patent is generally directed to wireless terminals that receive an A-MPDU (aggregated MAC protocol data unit) that includes a MSDU (MAC service data unit) or A-MSDU (aggregated MSDU) from multiple users and transmits back a block ACK (block acknowledgement) to at least some of those users, where the block ACK has a particular format dictated by the numerous elements of the claims. It has been asserted against Askey Computer Corporation and its routers, which are Wi-Fi 6 (802.11ax) enabled devices.

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. Like the '233, the '396 patent has been asserted against Askey and its routers, which are Wi-Fi 6 (802.11ax) enabled devices. The '396 patent is also related to U.S. Patent 11,664,926, which has been asserted against Samsung, HP Inc., and Askey.
