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 and class actions. 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 currently serves as co-lead national counsel in the opioid litigation, coordinating the defense of cases filed within the MDL as well as hundreds of matters pending in state court.
