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.
