Two more Wilus Wi-Fi patents challenged

On January 30, 2026, Unified filed an ex parte reexamination proceeding against U.S. Patent 12,166,587, owned by Wilus Institute of Standards & Technology, Inc., an entity of Good Day to Invent, Inc. The ‘587 patent generally related to how to identify padding in Wi-Fi trigger frames. The '587 patent has not been asserted itself, but it is the latest issued patent in a family being used in litigation.
