Robbie Manhas

Senior Associate


A former Federal Circuit clerk, Robbie Manhas is a member of the firm's Supreme Court and Appellate group.  His practice focuses on high-stakes appeals, with a particular emphasis on patent law and administrative law.  He has been the primary drafter of dozens of appellate briefs, and has presented oral argument in the Federal Circuit and the Sixth Circuit.

Robbie is a lawyer because he is passionate about legal analysis, writing, and advocacy—understanding how to properly frame and creatively answer challenging questions of law, and then communicate that understanding to others in a credible and efficient way.

Robbie's work includes wins in the Federal Circuit and other appellate courts, and spans a variety of industries and products, such as semiconductors and electronics, software, pharmaceuticals, agriculture, and sporting goods.  His work has also involved a number of U.S. agencies, including the Patent and Trademark Office, the Food and Drug Administration, the Department of Agriculture, and the Department of Labor.

Prior to joining Orrick, Robbie was a Senior Associate at Wilmer Cutler Pickering Hale and Dorr LLP, where he was a member of its Appellate and Supreme Court Litigation, Intellectual Property Litigation, and Government and Regulatory Litigation groups.  Before that, Robbie was a law clerk for the Honorable Richard G. Taranto of the Federal Circuit.
