Josh focuses his practice on representing both plaintiffs and defendants in complex civil antitrust litigation and investigations, with a particular focus on serving clients in the technology industry. His experience encompasses all areas of antitrust claims, including monopolization, conspiracy, unfair competition, and other restraints of trade. He leverages his prior role as a Senior Litigation Counsel for the U.S. Department of Justice’s Antitrust Division to provide strategic insights and effective advocacy in high-stakes antitrust matters.

While at the DOJ, Josh served as a member of the litigation and trial team in the United States v. Google search monopolization case.  During the ten-week trial, Josh examined and cross-examined key expert and fact witnesses. Josh also helped lead merger and conduct antitrust investigations in a variety of industries, including the technology, media, and sports industries.

Some of the experience represented below may have been handled at a previous firm.

  • Represented Fubo TV in a high-profile antitrust litigation concerning the streaming television industry.

Ariz.).
  • Represented Verizon and AT&T in telecommunications disputes in federal and state courts and before the Federal Communications Commission.
  • Briefed and argued an appeal in the Ninth Circuit concerning a question of first impression in the prisoner civil rights context. The panel unanimously ruled for the client and ordered a new trial based on an improper jury instruction. Hoard v. Hartman, 904 F.3d 780 (9th Cir. 2018).
