Wilus Wi-Fi patent challenge instituted

On October 7, 2025, six 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 10,820,233, 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.

Another ISG Wi-Fi 6 patent challenged

On October 1, 2025, Unified Patents filed an ex parte reexamination proceeding against U.S. Patent 11,641,670, owned and asserted by the International Semiconductor Group, an NPE. The '670 patent is directed to access points (APs) that are configured to use information that associates MAC addresses for terminals with association identifiers (AIDs) that are locally allocated to the terminals by the AP. The goal of this is to create a smaller list of AID-assigned terminals that is faster to search, and which allows the AP to respond quicker to the associated terminals. The '670 patent is one of over 20 patents divested from Toshiba in April this year and belongs to one of the largest families in that transfer. The '670 patent is challenged as part of Unified’s SEP Wi-Fi zone.
