Joseph Adamson

Of Counsel

Washington, D.C.

Joseph brings experience from private practice and government service to represent clients facing antitrust and other legal risks, including Sherman Act Section 1 and Section 2 conduct investigations and litigation, Clayton Act Section 7 merger review and litigation, and complex commercial litigation. Immediately prior to joining Orrick, Joseph was a trial attorney at the United States Department of Justice Antitrust Division, where he led and supported investigations into potentially anti-competitive proposed mergers and exclusionary unilateral conduct, and represented the United States in litigation challenging anticompetitive conduct.

In his government service, Joseph investigated potentially anticompetitive mergers, allegations of collusion, and potentially monopolistic conduct by firms in the healthcare and many other industries. That experience included working on the litigation team in the United States' challenge of UnitedHealth Group's acquisition of Change Healthcare. In private practice, Joseph has litigated antitrust and other complex commercial matters, advocated on behalf of clients with government agencies, and counseled clients on antitrust risks of potential acquisitions and on HSR filing requirements.

The combination of government and private practice experience, including representing both plaintiffs and defendants, allows Joseph to navigate the demands of modern discovery in litigation and by subpoena. Joseph seeks to achieve optimal outcomes for clients by minimizing disruption, cost, and burden during the litigation process, while focusing on and obtaining the key facts necessary to support his clients’ claims and defenses. His experience guides Joseph’s advocacy to secure successful outcomes at early stages of investigations and litigations, and to build the factual record needed to win at trial.

Joseph also maintains an active pro bono practice, including extensive work for clients seeking to prove their innocence from wrongful convictions.
