Scott Schaeffer is a counsel in O’Melveny’s Antitrust and Competition Group. His diverse practice spans the globe and involves complex antitrust and commercial litigation, antitrust counseling, and antitrust investigations. He also defends proposed and consummated mergers before antitrust agencies and in merger litigation.

Scott’s varied expertise includes representing U.S. and Asian clients in transactions in the technology, financial services, semiconductor, airline, biotech, foodservice, telecommunications, and manufacturing industries, among others. It also involves cutting edge monopolization and price fixing litigation. Scott has particular experience at the intersection of antitrust and intellectual property law, and regularly counsels clients on the antitrust implications of FRAND commitments and other aspects of the standards-development process.

His recent successes include merger clearance for Charles Schwab’s $26 billion acquisition of TD Ameritrade; defeating class certification on a multi-billion-dollar price fixing claim involving Optical Disk Drives in the Northern District of California; and the complete dismissal of monopolization and conspiracy claims involving energy companies in Hawaii.

Scott’s work has been recognized by leading publications around the world. In the U.S., Law 360 recently named Scott an antitrust “Rising Star” and the American Bar Association named Scott one of the “Top 40 Young Lawyers.” In Asia, The Legal 500 Asia-Pacific named Scott a “Rising Star” for antitrust and competition in China. Scott is a frequent author and speaker on a variety of subjects, including antitrust enforcement, foreign sovereignty, and the intersection of antitrust and intellectual property law.

Prior to joining O’Melveny, Scott was a law clerk for the Honorable A. Raymond Randolph on the U.S. Court of Appeals for the D.C. Circuit and the Honorable Gary Feinerman on the U.S. District Court for the Northern District of Illinois.
