701 Pennsylvania Avenue, NW Suite 200, Washington, DC USA 20004


Peter Boyle focuses his practice on antitrust litigation and counseling matters, in particular, antitrust issues relating to intellectual property, distribution matters and trade associations. He has substantial experience litigating private treble damages actions under both federal and state antitrust laws. Mr. Boyle has handled numerous complex litigation matters implicating the overlap between the antitrust and intellectual property laws, including antitrust and economic issues arising in patent cases, such as antitrust counterclaims, misuse defenses and patent damages claims. Several of these cases required not only a reconciliation of the tensions between the IP and antitrust laws but also a sophisticated analysis of how other bodies of law and regulatory schemes, such as FDA laws and regulations, affect competition in the relevant industries.

In addition to his litigation practice, Mr. Boyle also represents clients in connection with government investigations, including antitrust merger review and civil non-merger matters. He has represented clients before the Federal Trade Commission and the U.S. Department of Justice in connection with merger matters, including multinational and consummated mergers and investigations into alleged anticompetitive practices, and U.S. Department of Justice civil investigative demands relating to third-party payers’ contracts with health care providers. Mr. Boyle also has substantial experience counseling clients on gun-jumping and pre-merger integration planning issues in connection with large merger matters. He has represented clients in criminal antitrust matters and related internal investigations. Mr. Boyle has represented clients in litigation and government investigation matters in the telecommunications, financial services, health care, pharmaceutical and transportation industries, among others. Mr. Boyle has been recognized by the prestigious 2009 Legal 500 US in the area of Antitrust law. He has been named a Washington, D.C. “Super Lawyer” in 2020 and 2021 and also in 2018 and the five years immediately preceding for Antitrust Litigation and a “Top 100 Washington, D.C. Super Lawyer” in 2016 by Super Lawyers magazine.
