Stephen McIntyre is a versatile antitrust lawyer who represents clients in civil and criminal investigations, government enforcement actions, and high-stakes private litigation. Stephen brings skill, insight, and practicality to each matter—be it a nationwide class action, a suit against a client’s chief competitor, or an inquiry from a federal or state antitrust enforcer.

Stephen has secured victories for clients in the pharmaceutical, technology, and entertainment industries, among others. His recent successes include a Ninth Circuit victory affirming the dismissal of antitrust conspiracy claims against manufacturers of dynamic random access memory (DRAM) chips; a sweeping summary judgment win on behalf of ExxonMobil in an antitrust conspiracy case in which plaintiffs sought tens of billions of dollars in damages; the complete dismissal of monopolization and “reverse-payment” claims in In re Humira, an antitrust case involving the world’s highest-selling biologic drug; and an across-the-board summary judgment win in In re Optical Disk Drives, a consumer class action in which plaintiffs sought billions in alleged damages from major electronics companies.

In 2022, the Ninth Circuit unanimously affirmed the dismissal with prejudice of the indirect purchasers' complaint, which led the direct purchasers to abandon their appeal.

See In re Humira (Adalimumab) Antitrust Litigation, 465 F. Supp. 3d 811 (N.D. Ill. 2020), aff’d sub nom. Mayor & City Council of Baltimore v. AbbVie Inc., 42 F.4th 709 (7th Cir. 2022).
  • Defended ExxonMobil Corp. against an antitrust class action alleging that oil refiners colluded to increase California gasoline prices by reducing the supply of gasoline to the state.

  • Wrote the winning summary judgment brief on behalf of Samsung Electronics Co.
