John “Jay” Jurata is a first-chair antitrust trial lawyer with over 25 years' experience. His practice encompasses complex litigation, government conduct investigations, and mergers and acquisitions across both U.S. and international competition law. A former surface warfare officer in the U.S. Navy, Mr. Jurata is calm under fire when handling clients' most high-stakes matters. With a particular focus on digital platforms and the intersection of antitrust and intellectual property, his clients include Microsoft, Zillow, TikTok, Sonos and Sharp.
Mr. Jurata recently defended Microsoft in a high-profile lawsuit brought by Elon Musk which sought to unwind Microsoft’s strategic partnership with OpenAI. In May 2026, a unanimous nine-member jury ruled in Microsoft’s favor, and the court subsequently dismissed all remaining claims, including Musk's claim that Microsoft aided and abetted the alleged breach of charitable trust – marking a complete trial win and earning American Lawyer’s Litigator of the Week distinction.
In another recent high-profile case, Mr. Jurata served as lead trial counsel defending Zillow in an antitrust, false advertising, and unfair business practices lawsuit relating to the display of broker listing information. After a two-week trial, a federal jury in the U.S. District Court for the Western District of Washington completely rejected REX's claims for damages in excess of $1.2 billion before trebling. The Ninth Circuit affirmed the ruling, and the Supreme Court denied certiorari, marking a complete defense victory for Zillow.
Mr. Jurata represents Microsoft, Sonos and others as interested parties in the Department of Justice's antitrust lawsuit against Google. He also advises companies on algorithmic pricing, including defending a major residential apartment provider against price-fixing claims brought by the New Jersey Attorney General related to the use of algorithmic rent-pricing software. Finally, he has represented multiple companies in disputes involving standards-essential patents, including a “bet the company” trial victory for iBiquity Corporation.
