Who's Who Legal Competition: Lawyers

John Treece is a practice area team leader in the Sidley’s antitrust and competition practice. He also has meaningful experience in patent litigation and the intersection of antitrust and patent law.

In 2013, John led a trial team that won a $104 million judgment for client AstraZeneca by applying antitrust economic principles to obtain a “reasonable royalty” of 50 per cent of net profits from the fourth generic entrant to the market. In 2015, the Federal Circuit Court of Appeals affirmed $98 million of that judgment. He also recently represented AT&T Mobility in In re Text Messaging Antitrust Litigation, in which plaintiffs sought more than $10 billion in trebled damages for alleged price-fixing. In 2015, the Seventh Circuit Court of Appeals affirmed the grant of summary judgment in defendants’ favour. In June 2015, in a case alleging retailer monopolisation, the district court struck the plaintiff’s economic expert testimony after a 2-1/2 day evidentiary Daubert hearing, followed in July with an order entering summary judgment in favour of John’s client. And in 2015 and 2016, John settled cases alleging that client Astellas Pharma USA had delayed the entry of generic versions of a drug with direct purchaser and indirect purchaser classes for $98 million and $13 million, respectively.

John is a graduate of Harvard University (BA, magna cum laude, 1975) and Columbia University School of Law (JD, 1978).
