Marc Hearron is a partner in Morrison & Foerster’s Appellate and Supreme Court Practice Group.  Mr. Hearron has extensive experience handling appeals in complex matters, having briefed cases at every appellate level, including in the Supreme Court of the United States. He also has argued multiple cases in the Second Circuit, Ninth Circuit, and Federal Circuit and has a perfect record in his argued appeals.

In 2015, Marc was named to the National Law Journal’s elite list of D.C.’s Rising Stars.  In 2013, Marc was named to the National LGBT Bar Association’s list of Best LGBT Lawyers Under 40.

Mr. Hearron’s appellate practice mirrors the wide-ranging litigation breadth of the firm. He is particularly experienced in patent and bankruptcy appeals, including two significant bankruptcy wins in the Supreme Court and multiple patent victories in the Federal Circuit. The breadth of his experience also extends to many other subject matters, including antitrust, financial services, securities, and other intellectual property issues.

Mr. Hearron maintains an active pro bono practice.  He was lead counsel for the Guardian Ad Litem in V. L. v. E. L., in which the Supreme Court of the United States summarily reversed the Alabama Supreme Court’s refusal to recognize a Georgia adoption.  Among his other work, Marc has also submitted important amicus briefs to the Supreme Court in support of LGBT equality, and he has handled and won several immigration appeals.

Prior to joining Morrison & Foerster, Mr. Hearron clerked for Judge Carolyn Dineen King of the U.S. Court of Appeals for the Fifth Circuit and for Judge Sidney A. Fitzwater of the U.S. District Court for the Northern District of Texas. Mr. Hearron received his J.D. from Southern Methodist University Dedman School of Law, where he graduated summa cum laude and served as Editor-in-Chief of the SMU Law Review.
