    “Mr. Morris is committed to achieving the best possible outcomes for us.”


    Sean Morris represents clients in complex commercial litigation, with particular emphasis on mass tort, unfair business practices, and intellectual property and technology matters. Mr. Morris has served as lead counsel in several multidistrict litigations, class actions, and disputes involving international parties. He is head of the firm’s Los Angeles office.

    Among his significant cases, Mr. Morris successfully tried the California lead pigment litigation, in which public prosecutors asserted that former manufacturers of lead pigment should be held liable for the alleged health hazard created by the existence of lead paint on millions of private residences. He served as lead counsel in an MDL class action proceeding in which plaintiffs in more than 25 states alleged fraud and violation of state unfair business practice statutes arising from the technology used in the retail sale of gasoline, and he obtained an injunction against an Internet portal requiring it to cease infringements on its network of more than 300,000 websites.
