Paul Harold is an appellate attorney who helps clients win their most important cases when the stakes are highest. Of Counsel in Wilson Sonsini's Washington, D.C., office and a member of the firm's Supreme Court and Appellate practice, Paul is known for turning complex, cutting-edge legal problems into clear, persuasive briefs that move courts.

Paul’s work sits at the crossroads of technology, the Constitution, and business. He has briefed and helped win cases in the U.S. Supreme Court and regional federal courts of appeals and he regularly handles petitions seeking and opposing Supreme Court review. Clients turn to him for high-stakes appeals and dispositive motions in disputes involving the First Amendment, internet law, Section 230 of the Communications Decency Act, copyright and technology litigation, patent litigation, class actions, constitutional and separation-of-powers questions, administrative law, and complex commercial and international arbitration matters. Notably, Paul was part of the Wilson Sonsini team that prevailed in V.O.S. Selections, Inc. v. Trump—a blockbuster U.S. Supreme Court decision holding that the International Emergency Economic Powers Act (IEEPA) does not give the President the power to impose the sweeping "Liberation Day" tariffs.

Paul also has deep experience defending the free-speech rights of internet and technology companies. He represented the trade associations in Moody v. NetChoice, where the Supreme Court confirmed that a platform's editorial choices about what content to display are protected by the First Amendment. He has repeatedly defended online platforms in leading Section 230 and internet-law appeals, including Gonzalez v. Google in the Supreme Court, Ninth Circuit, and Northern District of California. Paul is also at the forefront of the copyright battles reshaping the technology industry, including copyright class actions and the wave of lawsuits challenging how generative AI tools are developed and trained.

Before joining Wilson Sonsini, Paul practiced in the appellate group of an international law firm in Washington, D.C., where his matters included work as part of the trial team in Beef Products Inc. v. ABC, one of the largest defamation cases in U.S. history.

After law school, he clerked for the Honorable John M. Rogers of the U.S. Court of Appeals for the Sixth Circuit.
