The head of Dilworth Paxson’s patent practice has made a move to Armstrong Teasdale, as the Am Law 200 firm continues to grow its Philadelphia presence.

Edward “Ted” Behm joined Armstrong Teasdale as a partner last week, the firm announced Monday. He was a partner at Dilworth Paxson for two-and-a-half years, also serving as chair of the firm’s patent practice. Before that, he practiced at Barnes & Thornburg.
