Dylan Carson is a trial attorney with significant experience in antitrust litigation, federal and state government antitrust investigations, and competition law counseling. For more than 20 years, Dylan has represented clients in federal and state court antitrust trials, before judges and juries, as both plaintiff and defendant. He is among the short list of antitrust attorneys to have successfully prosecuted and defended high-stakes merger trials. He has also represented clients before federal and state antitrust enforcers, including the U.S. Department of Justice (DOJ), Federal Trade Commission and state attorneys general. Prior to joining the firm, Dylan was a trial attorney in the Media, Entertainment, and Communications section of the Antitrust Division at DOJ.


Dylan offers clients his knowledge of public and private antitrust enforcement in Washington, D.C., and around the country to navigate the complexities of civil and criminal investigations and litigation. He has advised clients about shepherding mergers and acquisitions through the approval process, handling federal and state government antitrust investigations, and crafting compliance programs to avoid the risk of antitrust enforcement and treble damages actions. He has represented parties involved in merger and civil nonmerger investigations in diverse industries, including telecommunications, cable and satellite television, e-commerce, online platforms, energy generation, finance, casinos, and food and soft drinks. Notably, Dylan repeatedly has been involved in large, complex telecommunications and technology litigations, including monopolization cases and price-fixing prosecutions.

Dylan has significant experience working with expert witnesses, especially industrial organization economists, to prepare and present reports and opinions to courts, enforcers and regulatory bodies. He has taken and defended C-suite executive depositions, and represented companies and executives involved in criminal antitrust investigations in the semiconductor and medical device industries.

In high-profile matters at DOJ, Dylan gained significant exposure to the health care industry and many of its key market participants. In private practice, he has represented large, multinational manufacturers of branded and generic pharmaceuticals and medical devices, and been involved in large-scale multidistrict litigation, including the trial of bellwether cases. Through these cases and others, he gained extensive experience in the Noerr-Pennington sham petitioning area of antitrust jurisprudence.

For his efforts at DOJ, Dylan received the Attorney General’s Award for Distinguished Service, the second highest award for employee performance at the Department of Justice. For three years straight, he received the Assistant Attorney General Award of Distinction, the highest Antitrust Division performance award, based on his investigation and litigation work.

Before DOJ, Dylan was a partner at a national trial firm in Denver. After law school, he served as a law clerk in the District of Massachusetts for the Hon. Frank Freedman.
