A notable case for the firm is its representation of Razdog Holdings LLC in defense against patent challenges. Villegas Cefo served as counsel for Razdog Holdings LLC in Unified Patents, LLC v. Razdog Holdings LLC, where Unified Patents initiated an ex parte reexamination of U.S. Patent 10,334,068, related to interactive elements on a video player webpage. The Central Reexamination Unit subsequently granted Unified's request, finding substantial new questions of patentability for the challenged claims.
