We bring value to our clients in the following ways:

  • Cross-border coordination. We provide coordinated advice across borders that includes assisting clients with antitrust enforcement issues, merger clearances and multi-jurisdictional investigations. Such matters require an understanding of transnational law and regulation, as well as local law and tradition. Our cross-border capabilities extend to the strong international coordination we possess with local authorities in numerous jurisdictions around the world.
  • Deep government experience. Our team includes lawyers who have served as: Chairman of the Federal Trade Commission, Commissioner of the Federal Trade Commission, General Counsel of the Federal Trade Commission, Director of the Federal Trade Commission’s Bureau of Consumer Protection, Director of the Federal Trade Commission’s Bureau of Competition, trial lawyers for the Federal Trade Commission and the Antitrust Division of the United States Department of Justice and a lawyer in the State Administration for Market Regulation (SAMR). They provide an insider’s perspective regarding key government policies that impact antitrust matters. 
  • Economic perspective. We have a team of Ph.D.-trained economists who work with our antitrust lawyers to provide clients with economic analysis and empirical insight on sophisticated legal and policy matters. 
  • Integrated services. We collaborate with colleagues in Sidley’s white collar and government investigations, M&A and intellectual property practices to provide seamless advice on complex legal and business issues.
