Perkins Coie has bolstered its intellectual property group in Washington, D.C., with the hire of Nathan Kelley, a former top-ranking official and administrative judge at the U.S. Patent and Trademark Office.

Kelley, who is joining Perkins Coie as a partner, comes to the firm after stepping down as the solicitor and deputy general counsel for IP law at the USPTO. He previously served as the USPTO’s chief administrative patent judge, a role that put him in charge of the Patent Trial and Appeal Board.
