Noah is a partner in the Antitrust practice and splits his time between Washington, D.C. and Silicon Valley. He partners with clients to craft and execute global antitrust strategies while also representing them before US courts, the US Department of Justice, Federal Trade Commission, and the various states’ Attorney General offices.
Antitrust plaintiffs and enforcers are invoking the antitrust laws in increasingly novel ways in private litigation and government investigations. Noah provides creative and nimble strategies that are specific to his client’s business objectives, whether they are in high-stakes litigation or planning a transformative deal. He is singularly focused on understanding each client to provide practical, business-oriented solutions.
Noah draws on his 20 years of experience with complex cross-border antitrust issues, with a focus on how the antitrust laws intersect with intellectual property. He has successfully defended and asserted antitrust claims in merger and non-merger investigations before the enforcement agencies, and in federal district court.
Noah enjoys teaching on Antitrust and Innovation as an adjunct professor for antitrust at UC Berkeley School of Law. He is a prolific author and speaker on a range of competition topics, and contributes to American Bar Association (ABA) publications and commentary.
