Russell Cohen is a partner in Orrick's San Francisco office with experience litigating antitrust and other complex business disputes on behalf of companies and individuals, particularly in the technology sector.

Russell has extensive experience representing clients in company-critical antitrust and unfair competition matters, particularly in the technology sector. These complex cases require a deep understanding of issues such as multi-sided platform economics and strategy, software interoperability and the duty to disclose interface information; IP-related antitrust claims; and employee non-compete and other mobility-restricting arrangements. He has represented clients in direct and indirect purchaser antitrust class actions, unfair competition cases and competitor suits in state and federal court, as well as in arbitration and international forums. 

Russell also represents clients in other complex business disputes, including venture capital investor disputes, insurance recovery for financial, property and other losses, and other commercial matters in federal and state court, and in arbitration proceedings.

Russell also works with clients on data-breach response efforts, including utilizing cyber insurance as part of a coordinated, comprehensive strategy for managing and recovering from data breaches. 

Russell is committed to pro bono legal work and community service. He was counsel in the successful Alien Tort Statute case against one of the assassins of Archbishop Oscar Romero, who was murdered in El Salvador in 1980. He is currently representing a parent and child separated at the Southern border, has represented former Guantanamo detainees pursuing damages for torture and unlawful detention, and was amicus counsel for a group of Canadian and international human rights organizations and scholars in the U.S. Supreme Court in Arar v.
