Stefan Miller is a partner in the Intellectual Property Practice Group in Kirkland’s New York office. His practice focuses on patent litigation and counseling in the pharmaceutical, chemical and biochemical arts. He has extensive experience in all aspects of litigation including pre-litigation investigations, fact and expert discovery, depositions, oral argument, technical reports and analysis, Markman and summary judgment proceedings, brief writing and trial before the Patent & Trademark Office, ITC, and Federal District Courts. Stefan has also been a primary drafter of over sixty technical expert reports in a variety of technological fields including small-molecule compositions and formulations, biologics (including CAR-T technology), medical devices, and recombinant DNA technology. As part of his practice, he works closely with leading experts to scour the literature, identify the soundest technical foundations of a case, and ultimately translate complex scientific theories into simple, compelling themes resonating with judge and jury. Stefan’s practice also includes significant experience with the intersection of patent and commercial law, including patent licensing and other contractual disputes.

Stefan utilizes his first-hand experience with the prosecution of patent applications, bringing with him an inside look at the back and forth between patent applicant and the USPTO. Using his several years of prior patent prosecution and counseling experience, Stefan discovers weaknesses in patent families. When defending a client’s patents, he identifies the best defenses in protecting a client’s intellectual property, and when on the attack, leverages his insight into a patent’s file history to muster the best offense. He also routinely conducts expansive freedom-to-operate and other IP due diligence projects.

Stefan has an in-depth and broad-ranging technical background across several fields. He earned a Ph.D. in organic chemistry from Yale University, where he researched the synthesis of small-molecule drugs with applications in oncology, and has extensive experience in several additional technical fields during his past decade-plus of legal work.
