Who's Who Legal Competition: Lawyers

Ken O’Rourke represents established and emerging companies in complex, multi-forum civil litigation and government investigations, including: antitrust cases such as class actions, monopolisation, international cartels, merger litigations, intellectual property lawsuits involving antitrust issues such as reverse payment pharmaceutical antitrust cases and FTC investigations, patent misuse, Walker Process claims, and patents enforced on industry standards; and complex business, technical and financial litigation.

He represents leading companies accused of participating in international price-fixing cartels, litigated such cases as the US Department of Justice’s lawsuits seeking to block US Airways' merger with American Airlines and AT&T’s proposed merger with T-Mobile, and defended against Rambus Inc’s worldwide litigation campaign to enforce patents on industry-standard computer memory products. In 2013, Ken served as special prosecutor trying a criminal vehicle manslaughter case to a California jury. 

Drawing upon his 30 years of litigation experience and legal leadership at O’Melveny, Ken also served as interim Chief Legal Officer of one of the US's largest health insurers, chaired the California State Bar antitrust and unfair competition law section, currently chairs the Antitrust Litigation Forum, and is a continuing member of the ABA antitrust section's international cartel task force. Ken is ranked by Chambers USA, quoting commentators saying “He’s a spectacular lawyer” who “wins particular acclaim for his cartel work”. 

WWL says: Kenneth O’Rourke is internationally recognised for his outstanding abilities as a competition litigator.
