William M. Jay

Willy Jay is a partner in Goodwin’s Appellate and Supreme Court Litigation practice. After ten years leading that practice, he recently became co-chair of Goodwin’s broader Complex Litigation and Dispute Resolution practice. Willy uses his deep experience litigating before the U.S. Supreme Court and U.S. Courts of Appeals, including more than 80 oral arguments, to help clients formulate winning appellate strategy. His appellate skill led Benchmark Litigation to name him the nationwide Appellate Lawyer of the Year for 2020. A former Assistant to the Solicitor General and Supreme Court clerk, he has argued 17 cases before the Supreme Court, briefed more than 60 Supreme Court cases on the merits, and briefed more than 150 cases at the certiorari stage. In recent years he argued five of the most significant intellectual-property cases at the Court, involving patent, copyright, and trademark law.

Willy has handled cases in every federal court of appeals as well. He has filed more than 300 briefs in federal and state appeals courts and argued in 11 federal circuits. He is a prominent advocate at the Federal Circuit, where he has argued 30 times, filed more than 120 briefs in patent appeals, and been recognized as “Appellate Litigator of the Year" by both Managing IP and LMG Life Sciences. Willy also regularly counsels clients on appellate strategy at the trial level, preparing and arguing key motions and post-trial briefing before district courts and federal and state administrative agencies.

Willy is recognized in Band 1 in two different appellate categories in Chambers USA: America’s Leading Lawyers for Business, where clients praise him for being "a rocket scientist" whose "spectacular brief writing" and "keen and analytical mind" enable him to “take any issue on appeal.” Another client noted that Willy "is an extraordinary litigator" who "has a unique way of synthesizing complex arguments and making them understandable." Other clients comment that Willy is “A super-efficient appellate litigator who is able to cut straight to the most critical issues and construct simple, persuasive arguments from extremely complex legal and factual records." Forbes named him to its inaugural list of America’s Top 200 Lawyers. Willy is also listed in Legal500 and Best Lawyers in America. Law360 named him an “Appellate MVP.” He has been named “Litigator of the Week” by the AmLaw Litigation Daily.

Willy has particular experience in appellate cases involving intellectual property (including patent, copyright, and trademark law), financial services, administrative law (with a particular focus on pharmaceutical regulation), environmental law, class action practice, federal preemption of state law, and the First Amendment (including campaign finance regulation, election law, and election crimes).
