John W. Treece

JOHN TREECE is a practice area team leader in the firm’s Antitrust and Competition practice. In the 2017 edition of The Best Lawyers in America, John was recognized as a “Lawyer of the Year” in the area of Antitrust Law. Also in 2017, LMG Life Sciences selected him as one of six candidates for Antitrust Litigator of the Year. In 2015, Benchmark Litigation named John a “Litigation Star,” listed him among the Top 100 Trial Lawyers in the U.S.; in 2015 and 2016, he was one of six finalists for Benchmark’s Antitrust Lawyer of the Year. Recent notable cases include:

– In November 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% of net profits from the fourth generic entrant to the market. In April 2015, the Federal Circuit Court of Appeals affirmed $98.5 million of that judgment.

– He 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 of “pay per use” text messages. In April 2015, the Seventh Circuit Court of Appeals affirmed the grant of summary judgment in defendants’ favor.

– In June 2015, in a case alleging retailer monopolization, the district court struck the plaintiff’s economic expert testimony after a 2-1/2 day evidentiary Daubert hearing, followed in July 2015 with an order entering summary judgment in favor of John’s client.

– From 2008 to the present, John has represented SSAB Swedish Steel in a price-fixing case brought against all major U.S. steelmakers, alleging a collusive restriction of output. SSAB alone filed a summary judgment motion while plaintiffs’ class certification motion was pending, leading to focused, limited discovery and a 2016 settlement that, on a per market share basis, was the least costly of any in the case and 75% less than the average settlement.

John has been recognized as one of the country’s leading antitrust lawyers in such publications as Chambers USA (ranked since 2004; Illinois–Band 1; U.S. and Global–Band 3); U.S. News and World Report; Global Competition Review: Who’s Who Legal (as the only ranked antitrust lawyer in Illinois); The Legal 500 US; and PLC: Which Lawyer? (highest ranking for antitrust law). Since 2012, he has been a “Life Sciences Star” in LMG Life Sciences. Client and peer comments include “very strong technically and extremely responsive” (The Legal 500 2009); “a great writer, a practical litigator and someone creative enough not to have to always go by the book” (Chambers USA 2007), and “good with the big picture” and “a fierce competitor” (Chambers USA 2014).
