Vinson & Elkins’ nationally recognized Antitrust and Competition law practice brings clients more than 50 years of experience handling every aspect of antitrust, including grand jury investigations into cartel conduct, joint ventures, global mergers and acquisitions, civil litigation, and antitrust investigations, which have involved monopolization, exclusive dealing, tying, boycotts, and unfair trade practices under state and federal laws.

We have a team of lawyers located throughout the country dedicated to handling antitrust matters for our multinational and domestic clients across a wide array of industries. V&E's interdisciplinary approach leverages the skills and experience of our Litigation, White-Collar Defense, Intellectual Property, Corporate, Appellate, and Securities practices to provide thorough representation and optimum results for our clients.

Scope of Practice

Our Antitrust lawyers provide pre-litigation counseling to clients on highly complex mergers, acquisitions, and competitor collaborations. Additionally, we are among the leading firms in filing pre-merger notifications in the U.S. and under multi-jurisdictional merger control regimes, and we lead some of the largest and most complex transactions to successful closings. When necessary, our core team of seasoned litigators is prepared to aggressively defend claims in state and federal courts, as well as investigations and enforcement proceedings before the Federal Trade Commission, the DOJ’s Antitrust Division, federal regulatory agencies, and state attorneys general.

Experienced Team

V&E’s strong reputation rests on our lawyers’ successful defense of bet-the-company claims in governmental actions, putative class actions by direct and indirect purchasers, and claims brought by opt-out plaintiffs throughout the country, in both federal and state courts. Our success results from an Antitrust team with significant government and regulatory experience, including former DOJ prosecutors and proven trial lawyers able to effectively defend companies and individuals summoned before grand juries or indicted for alleged antitrust offenses. Our team possesses a deep understanding of the approaches, arguments, and economics necessary to see a transaction through to approval by the appropriate regulatory agencies. We also aggressively represent clients when their businesses are injured by anti-competitive conduct — including a victory amounting to the largest antitrust jury verdict of its time, totaling a $1.035 billion judgment with a net amount of $425 million ultimately received by the client.
