Rich Parker is one of the foremost antitrust lawyers in the United States, frequently called on by companies to save the day at the eleventh hour. As Chair of the Firm’s Antitrust and Competition Practice, he has achieved numerous victories for clients both before enforcement agencies and in the courts. After Rich served as lead trial counsel and negotiated a very favorable settlement for US Airways that resolved the DOJ’s attempt to block the airline’s merger with American Airlines, Global Competition Review recognized him as “Litigator of the Week” and said that, “[i]f O’Melveny & Myers partner Rich Parker wasn’t already the most famous antitrust litigator in America, he probably is now.” Global Competition Review also named the litigation “Antitrust Matter of the Year” and selected Rich as a finalist for “Lawyer of the Year.

Rich is both a trial lawyer and an antitrust regulatory lawyer.  He has been involved in many major antitrust representations, including criminal, merger, and government civil investigations, as well as class action litigation. He regularly represents clients before the FTC and the Department of Justice Antitrust Division on mergers, conduct investigations, criminal matters, and policy issues.
