Another International Semiconductor Group Wi-Fi 6 patent challenge instituted

On December 19, 2025, two months 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 claim of U.S. Patent 11,363,595, owned by the International Semiconductor Group, an NPE. The '595 patent is generally directed to transmitting a first frame on a first channel that identifies a second channel that can be used, and then receiving frames via both channels. This is particularly relevant to Wi-Fi devices that can operate in two frequency channels or bands, i.e., the 2.4 and 5 GHz bands.
