John DeQ. Briggs is one of the most accomplished competition lawyers of his generation. Since 1973, John has been antitrust and litigation counsel of choice for dozens of major companies in the United States, Asia, Europe and Scandinavia. Client demand for his work has mainly focused on antitrust, M&A and complex civil litigation, including especially matters implicating shareholder liability and jurisdiction based on principles of veil piercing, agency and alter ego. Prior to joining Axinn, John served for more than 10 years as the Chair of the antitrust practice for Howrey LLP, during his tenure the largest private antitrust practice in the world. From 2009 until 2019 he was an adjunct Professor of International Competition Law at George Washington University.

John is also a past Chair of the American Bar Association’s ten- thousand-member Section of Antitrust Law; a Senior Fellow in the Litigation Counsel of America, The Trial lawyer Honorary Society; and has also been elected a Fellow of the American Bar Foundation.

John has been a prolific writer, having published some 50 articles and edited an edition of the ABA Antitrust Section’s flagship publication Antitrust Law Developments. He has recently published his first major non-legal book entitled America in Turmoil: Essays on Politics, the Economy, Society, and the Future, which has been favorably reviewed.

In addition:

  • John has served as an expert witness on U.S. antitrust law at the behest of companies and law firms in proceedings around the world, including Australia, Canada, Switzerland, the United Kingdom and the United States.
  • John has represented one or both merging parties in fully litigated successful merger cases against both the FTC and the DOJ and was engaged as Special Trial Counsel by the Comptroller of the Currency to defend at trial a bank merger approved by the Comptroller yet challenged by the DOJ.
  • John has been lead counsel for antitrust non-merger and other complex business disputes in the federal or state courts of some twenty-five states, and has been lead counsel on appellate matters in the Supreme Court and in the Second, Third, Fourth, Fifth, Sixth, Ninth, Eleventh, and Federal Circuits.

John has been recognized by his peers and by numerous publications as at the top of his field. For example:

  • He is classified by Chambers and Partners as “incredibly smart,” “very articulate,” and a “Leader in his Field”
  • He is a repeat recipient of the BTI Client Services "All-Star" Award based on nominations by Fortune 1000 Chief Legal Officers for “client focus, delivery of results, and exceptional understanding of clients’ business"
  • Global Competition Review featured him as one of a small number of antitrust lawyers enjoying “A Decade at the Top” and otherwise characterized him as a "Great Courtroom Lawyer”
  • He has been recognized for more than a decade as a “Washington, DC Super Lawyer” and has been named among the “Best Lawyers in America” each year since at least 2005.
