Sean Gates

Called a “real trial lawyer,” Sean Gates is a nationally recognized antitrust and commercial litigator.  A former government enforcer, Sean has won trials involving a range of issues—such as equity compensation, fraudulent conveyances, and patent infringement damages.  But he has particular expertise in antitrust; he is one of the select few lawyers nationwide who has tried multiple antitrust cases.

Sean’s knack for winning has been recognized by peers and clients. In Chambers USA, he has been described as a “talented litigator” and “splendid antitrust lawyer” with an “excellent attention to detail,” “who efficiently manages discovery with an eye toward summary judgment and trial.”  He was named a “Lawyer of the Year” for antitrust litigation by Best Lawyers and an “Attorney of the Year” by California Lawyer.  He is designated a Litigation Star by Benchmark Litigation for commercial and antitrust litigation, ranked among the Southern California Super Lawyers for antitrust litigation, and recommended in Who’s Who Legal: Competition.

Sean’s expertise in substantive antitrust law has also been recognized.  He has written for the leading antitrust publication, the Antitrust Law Journal, presented before the Federal Trade Commission, edited treatises on the intersection of antitrust, intellectual property, and standard setting, and is a contributing author to the Antitrust Adviser.  He has also served in the leadership of the ABA Section of Antitrust Law for over 20 years, including as a member of the governing Council.

Prior to forming Illovsky Gates & Calia, Sean was a partner at Morrison & Foerster LLP and founded an antitrust litigation boutique.  Sean also served as a Deputy Assistant Director at the Federal Trade Commission, leading enforcement actions challenging anticompetitive conduct, where he received the Distinguished Service Award.
