WilmerHale “is our firm of choice for intricate and testing matters.”
Chambers USA quoting client statements about WilmerHale’s antitrust practice

WilmerHale has one of the premier antitrust litigation practices in the world. We are consistently recognized by Chambers and Global Competition Review as a leading antitrust firm both in the United States and Europe. To that strength we add one of the world’s leading litigation and arbitration practices—recognized for our ability in cartel cases, intellectual property litigation and US Supreme Court advocacy. Unlike many other firms, our antitrust litigators are not just general litigators who have handled an antitrust case or two at some point in their careers. Instead, we have more than 20 lawyers for whom antitrust litigation is their primary or sole practice, and more than 40 more for whom antitrust litigation is a substantial percentage of their overall practice.

Throughout the US, UK and Europe we have successfully represented clients in major antitrust litigation. We have compiled a remarkable record of resolving antitrust claims through summary disposition, at trial, and on appeal against both private and government plaintiffs in the United States. We also have substantial experience in litigating against the European Commission and national competition authorities before the European Courts and the national member state courts.


Currently, we are defending clients in several ground-breaking private antitrust suits in the UK, Germany and the Netherlands. In addition, we often are engaged as coordinating counsel in global antitrust litigation matters, supervising litigation not only in the United States and Europe, but in Australia, Canada and elsewhere around the globe.

Representative matters include:

  • FTC v. Intel Corporation (FTC). Defending Intel in the FTC's administrative complaint alleging violations of Section 5 of the FTC Act and antitrust violations relating to monopolization in computer microprocessor and other computer-related markets.
  • In re Automotive Parts Investigation (U.S.D.C. E.D. Mich.). Representing Japanese auto parts manufacturer DENSO and its US subsidiary in a criminal antitrust investigation and civil class action litigation. We secured a favorable settlement on behalf of DENSO with the Department of Justice in the largest antitrust investigation in US history.
  • FTC v. Cephalon; King Drug v. Cephalon; Vista Healthplan v. Cephalon; Apotex v. Cephalon (U.S.D.C. E.D. Pa.). Defending one of the world's fastest-growing biopharmaceutical companies in multiple lawsuits, including one brought by the FTC, challenging patent litigation settlements between Cephalon and four companies seeking FDA approval to market generic versions of Cephalon's leading pharmaceutical product, Provigil®.
  • In re Air Cargo Antitrust Litigation (U.S.D.C. E.D.N.Y.). Defending a major European air carrier in more than 100 consolidated private antitrust class action damage claims arising from the Justice Department's investigation into alleged price fixing among major air cargo carriers. We negotiated a favorable settlement and are assisting the companies in their ACPERA cooperation.
  • Research in Motion Ltd., et al. v. Motorola, Inc. (U.S.D.C. N.D. Tex.). Asserting antitrust and breach of contract claims in the US District Court for the Northern District of Texas arising out of a competitor's refusal to license patents declared essential to ETSI and IEEE on fair reasonable and non-discriminatory (FRAND) terms.
  • In re Payment Card Interchange Fee and Merchant Discount Antitrust Litigation (U.S.D.C. E.D.N.Y.). Representing a major MasterCard issuer in defending against a massive, multidistrict antitrust class action filed on behalf of merchants against Visa, MasterCard and the major payment card issuers alleging that the interchange fees set by Visa and MasterCard for processing credit card transactions are unlawful.
  • Princo v. International Trade Commission (Fed. Cir.). Representing Philips in persuading the Federal Circuit en banc to overturn a two-to-one panel decision that held that an exclusive cross-licensing agreement between Philips and Sony constituted patent misuse, and in successfully opposing petition for certiorari.
  • In re Insurance Brokerage Antitrust Multidistrict Litigation (U.S.D.C. D.N.J.). Representing one of the leading US insurance carriers in defending against a massive antitrust and RICO class action filed against most of the country's leading insurance carriers and brokers in the wake of Eliot Spitzer's investigation of Marsh McLennan and other major insurance brokers. The district court three times granted our motions to dismiss all claims in the case. WilmerHale Partner Seth Waxman argued the appeal of the final decision dismissing the claims with prejudice before the Third Circuit on behalf of the 15-defendant joint defense group. The Third Circuit's decision is pending.
