On October 29, 2025, Unified Patents filed an ex parte reexamination proceeding against 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. This filing marks the tenth patent challenged in Unified’s recently created SEP Wi-Fi zone.
