Weil, Gotshal & Manges LLP

The team at Weil, Gotshal & Manges LLP draws on experience arguing cases before all thirteen federal circuits and the U.S. Supreme Court, as well as in various state intermediate and supreme courts. The group's broad caseload regularly features matters involving antitrust, IP, the Foreign Sovereign Immunities Act, bankruptcy and class action. Leadership is shared between Washington, D.C.-based Mark Perry; New York-based Gregory Silbert; and Zachary Tripp, who splits his time between the two cities. Recent years have seen the team act for Regeneron against Novartis in both the Second and Federal Circuits in an antitrust dispute involving a multi-billion dollar eye treatment franchise; and secure a Ninth Circuit win for Apple in a Section 230 CDA case involving a fraudulent cryptocurrency app.
