Recognized as a
leading antitrust
lawyer in New York
by Chambers USA 2020

Olivier N. Antoine is a partner in Crowell & Moring's Antitrust & Competition Group in the firm's New York office.

Olivier's practice involves antitrust counseling on a broad range of competition and antitrust law matters in the United States and abroad, with particular focus on mergers, acquisitions, and joint ventures, as well as U.S. and international monopolization and cartel matters.

Olivier has extensive experience representing corporate clients in difficult merger and antitrust investigations before the Federal Trade Commission, the Department of Justice, the European Commission, SAMR, and many other foreign antitrust agencies. In addition, his practice includes civil and criminal antitrust enforcement matters, private antitrust litigation, and compliance and audit counseling.

Olivier has been ranked by clients and peers in Chambers USA since 2013 as a leading lawyer in Antitrust (New York). Olivier has also been recognized by Global Competition Review's Who's Who Legal of Competition Lawyers in New York since 2010. Olivier's practice was highlighted in the "Highly Recommended" section of Global Competition Review's Surveys of the New York Antitrust Bar:

"Perhaps no New York antitrust team has boosted its profile more in the past year than Crowell & Moring… and Who's Who Legal Nominee Olivier N. Antoine… manage the kinds of competition cases that could make its rival envious. The New York team has the ability and expertise to handle every kind of antitrust issue, from merger to criminal prosecutions, and do it well."

Olivier has significant experience handling strategic antitrust matters before antitrust agencies overseas. He has defended companies in antitrust and merger investigations in more than thirty jurisdictions outside of the United States, including the European Union, Canada, Germany, France, Mexico, Brazil, Chile, Spain, South Africa, Korea, Pakistan, Taiwan, and the People's Republic of China. The breadth of his international experience includes several protracted Phase II investigations before the European Commission, the South African Competition Commission, SAMR, and Brazilian antitrust authority CADE.

Olivier's work has covered a broad range of industries, including satellite radio, recorded music and music publishing, telecommunications, fixed satellites, television broadcasting, oil and gas, paper and forestry products, pharmaceuticals and medical devices, food products, bread, spirits, beer, vitamins, textiles, chemicals, fertilizers, sports goods, airlines, automotive and automotive parts, semiconductors, media buying, banking, financial services, and private equity.
