Jessica C. Kaiser

Jessica C. Kaiser, global head of the firm’s Patent Litigation practice and co-head of its Post Grant Proceedings practice, represents established and emerging technologies, telecommunications, and life sciences companies in complex IP disputes, including litigation and post-grant patent challenges such as IPRs, post-grant reviews, and ex parte re-exams. As a lead administrative patent judge at the U.S. Patent and Trademark Office (USPTO), Jessica managed and decided numerous cases before the PTAB in AIA trials. These included both IPRs and post-grant reviews and ex parte appeals during the original prosecution of patents. She also worked closely with USPTO and PTAB leadership to develop and implement PTAB reforms, such as agency rulemaking, a pilot program for motions to amend patent claims during AIA trials, PTAB statistics, and remote hearing operations.

Before joining the USPTO, Jessica was a partner at another large international law firm focused on patent litigation before U.S. district courts and the International Trade Commission. Jessica was also a staff attorney in the Office of General Counsel at the U.S. Court of Appeals for the Federal Circuit. In this role, she provided legal advice to the court, including mandamus petitions and all types of motions filed prior to an appeal being assigned to a merits panel.

Since returning to private practice in 2022, Jessica has been counsel in over 100 PTAB proceedings, and she has achieved notable successes including during the tenure of the current USPTO leadership. Jessica is ranked in Chambers USA for IP: Patent Trial and Appeal Board and in the Intellectual Asset Management (IAM) Patent 1000. Earlier in her career, she clerked for the Honorable Paul R. Michel at the Federal Circuit and for the Honorable Joan B. Gottschall at the U.S. District Court for the Northern District of Illinois.
