Christopher Ricciuti is a partner in the firm’s Patent Litigation and Post Grant Patent Proceedings groups. His primary focus is on litigating mechanical, electrical, and computer software patents in federal courts, along with pursuing and defending against patent validity challenges before the United States Patent and Trademark Office (USPTO). Mr. Ricciuti regularly practices at the confluence of district court litigation and trial proceedings at the USPTO, including inter partes review trials.

On behalf of Roku, Mr. Ricciuti was part of the trial team that secured a complete non-infringement verdict in the Waco Division of the Western District of Texas (MV3 Partners v. Roku). He is also recognized as a leading practitioner in Post-Grant proceedings at the USPTO, where he has been named as counsel on over 70 individual matters.

In addition to litigating cases in the federal district courts, USPTO, and handling Federal Circuit appeals, Mr. Ricciuti advises his clients on litigation procedure strategies, litigation avoidance, and the overall protection, exploitation, and enforcement of their patent portfolios. Mr. Ricciuti's experience spans a wide range of technologies including consumer electronics and smartphones, cloud and distributed computing systems, business methods, communication protocols, GPS systems, automotive technologies and automotive manufacturing processes, oilfield services and equipment, medical devices, pharmaceuticals, cosmetics, and industrial designs.

While in law school, Mr. Ricciuti served as a judicial extern for Judge Sue L. Robinson of the U.S. District Court for the District of Delaware.
