Operating at the European Union’s political and legislative center, O'Melveny's team in Brussels, Belgium focuses on EU and national competition law, as well as trade and sector regulation. Our lawyers are qualified in key member states, have in-depth experience and knowledge of national laws and procedures, speak local languages, know the national authorities, and are accustomed to coordinating complex cross-border projects in the EU and beyond.

We offer seamless antitrust and competition representation in the United States, Europe, and Asia. Members of our team routinely represent clients before antitrust and competition agencies around the world. Since its founding in 2004, the Brussels office has been involved in a series of high-profile cases covering all main areas of EU competition law (Article 102, mergers, and cartel cases), achieving headline-grabbing results for our clients.

With a combination of US, European and Asian antitrust knowledge, O’Melveny is well positioned to advise on the transnational implications of deals. This is a critical aspect of international business as antitrust authorities around the world conduct parallel merger inquiries and monopoly and cartel investigations. Few firms can match our consistent strength across these three major economic areas.
