Ken O’Rourke leads O’Melveny’s Los Angeles litigation practice, where he represents established and emerging companies in complex, multi-forum civil litigation in federal and state courts, including: antitrust cases such as class actions, monopolisation, international cartels, government investigations, merger litigations, unfair competition and reverse-payment settlements; 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 controversies and 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 and T-Mobile’s planned merger, and defended against Rambus Inc’s worldwide litigation campaign to enforce patents on industry standard computer memory products, the most recent ruling of which was a US$250 million sanctions award against Rambus and in favor of SK hynix for document spoliation. 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 at O’Melveny, this year Ken also has been serving as interim Chief Legal Officer of one of the nation’s largest health insurers. Ken is the past chair of the California State Bar antitrust and unfair competition law section and 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”.
