Introduction

Jessica advises clients on post-grant challenges of issued patents, bringing to bear her nearly two decades of experience.

Jessica C. Kaiser represents established and emerging technologies, telecommunications, and life sciences companies in complex IP disputes, including post-grant patent challenges such as inter partes reviews (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 Patent Trial and Appeal Board (PTAB) in America Invents Act (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 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.
