Champions for fair and competitive markets.

When corporations use their market power to hurt workers, consumers, investors or entrepreneurs, we fight back to ensure markets work for everyone.


We have earned a sterling reputation as one of the most widely respected plaintiffs’ antitrust practices in the country. We combat anticompetitive business practices through complex litigation that challenges price-fixing, wage suppression, group boycotts, and other anticompetitive behavior. Our clients include pension funds, hospitals, workers, and individual consumers. Our class action experience spans industries, including labor, finance, agriculture, automotive parts, chemicals, health care, high tech, media and entertainment, pharmaceuticals, and others.

We gladly take on – and defeat – formidable opponents, which have included such giants as Dow Chemical, Goldman Sachs, and Google.


Our attorneys have helped shape the antitrust landscape. Many have served as judicial law clerks; some in the Department of Justice and other governmental agencies, while others have experience litigating for the defense and bring special insight into the strategies of opposing counsel. All are adept at navigating the complexities of industry-specific economics.

As lead or co-lead counsel in some of the nation’s most complex cases we have recovered billions of dollars in damages for injured plaintiffs

  • We achieved a record-setting recovery as co-lead counsel In re Urethane Antitrust Litigation, a price-fixing class actionAfter settling with several defendants for $139 million, we went to trial against The Dow Chemical Company and obtained a $400 million jury verdict. After offsetting the prior settlements and trebling as provided for by statute, the court entered judgment against Dow for $1.06 billion dollars. The case against Dow ultimately settled for $835 million while Dow’s petition for certiorari was pending before the U.S. Supreme Court. Including the Dow settlement, we recovered a total of $974 million for the class – nearly 250% of the damages found by the jury. The jury verdict was the largest price-fixing verdict in the history of the United States, and the largest jury verdict in the country in 2013.  
  • Cohen Milstein currently serves as co-lead counsel in the Securities Lending Antitrust case, which alleges a group boycott of various platforms attempting to modernize the market for securities lending by the world’s largest investment banks.  Partial settlements of $580 million are awaiting court approval while the case is ongoing against Defendant Bank of America.
  • As co-lead counsel in the Electronic Books Antitrust Litigation, which alleged that Apple and five of the six biggest publishers in the U.S. conspired to raise the price of e-books, we litigated together with the Department of Justice and attorneys general from 33 states and territories. The case culminated in a settlement of $560 million, including a settlement of $450 million with Apple shortly before trial.
