MJ Moltenbrey, a former longtime Justice Department antitrust lawyer, is joining Paul Hastings LLP in the antitrust and competition division as a partner.
Moltenbrey served as the director of non-civil mergers in the department’s Antitrust Division from 2000 to 2002, and chief of the division’s Civil Task Force from 1995 to 2000. In her 17-year career with the department, she helped prosecute United States v. Microsoft, the antitrust lawsuit that alleged Microsoft was using its operating system Windows to monopolize the PC market; and United States v. Vista Int’l et. al., the proposed merger of the United Airlines and U.S. Air.
“MJ’s arrival adds to our Washington antitrust reputation and further reinforces our growing competition and M&A capabilities,” William Sullivan, chair of the litigation practice said in a news release.
Since March 2011, Moltenbrey has worked for Dewey & LeBoeuf LLP, which filed for Chapter 11 bankruptcy earlier this week. Moltenbrey’s previous practice focused on representing clients in front of the Justice Department and Federal Trade Commission on mergers, civil and criminal conduct cases and administrative proceedings. She has defended clients against civil investigations including intellectual property licensing practices, joint ventures and alleged monopolization charges, according to the news release.
Moltenbrey received her B.A. from Boston College in 1981 and her J.D. from the college’s law school in 1984.
Paul Hastings LLP is an international law firm that serves the financial industry and Fortune 500 companies. Moltenbrey will be joining the firm’s Washington, D.C. office.
