Antitrust & Competition

Antitrust News & Briefs


Our US antitrust and EU competition law practice has five major areas of focus: mergers, acquisitions and cartels; regulated and deregulated industries; complex litigation, including class actions; criminal antitrust investigations and prosecutions; and EU State aid notifications, investigations, and complaints. With more than 25 attorneys practicing antitrust and competition law across various industry sectors, Steptoe has the depth of experience to effectively assist clients with their antitrust and competition needs.

We represent clients in merger and cartel investigations in the United States before the Antitrust Division of the Justice Department, the Federal Trade Commission (FTC) (where many of our antitrust partners have worked), and the US Congress; and in the European Union before the European Commission’s Directorate General for Competition (DG Comp).  As competition law enforcement has spread around the globe, so has our experience in advising clients on merger and cartel matters in various other jurisdictions, including EU member states, China, Japan, and Korea.

Our antitrust lawyers have substantial experience managing the many complexities of parallel premerger proceedings and business-practice investigations by foreign competition authorities.  We have prepared premerger filings, defended investigations, and supervised teams of local counsel in all major countries with active antitrust regimes.  For European filings and investigations, we draw on our Brussels and London offices, as well as our Washington base.

With the support of the firm’s strong regulatory practices, we represent clients in many industries that are regulated or have been deregulated in recent decades.  We regularly advise clients on antitrust issues as they affect the chemicals, pharmaceuticals, electric utility and power generation, telecommunications, airline, railroad, trucking, pipeline, maritime, financial services, and other industries.

We represent clients as defendants in private class actions, other complex treble-damage litigation, and parens patriae cases brought by state attorneys general.  We are also experienced with handling state court class actions based on the unfair trade practice and consumer protection theories that plaintiffs often use to avoid federal court.  Our antitrust litigators appear in courts across the country.

Our white-collar criminal defense practice—one of the most significant in Washington and New York—features leading lawyers with extensive experience in the Justice Department before entering private practice.  These white-collar attorneys have defended corporations and top management in several recent high-profile criminal antitrust investigations and prosecutions.

In addition to the full range of competition and antitrust issues, our Brussels team also covers the uniquely European regulation of State aid-public tax or other financial programs that support individual companies or industries subject to oversight by the European Commission’s Directorate for Competition. The team includes a lawyer with more than a decade of experience as both an enforcer and adviser to both Governments and private-sector companies.

Our antitrust practice comprises the following:
