For a wide range of clients innovating in the medical diagnostics and imaging, medical devices, wireless communications, network architecture and security, and e-commerce industries, Paul B. Stephens protects the value of their businesses in all aspects of patent law, including prosecution, counseling, opinions and litigation. Clients often come to him with highly complex technological subject matter because of his broad experience and technical proficiency, built on his graduate studies in electrical engineering and advanced research in non-linear phenomena. In addition to his client-focused work, Paul also serves as Chair of the firm’s Pro Bono Committee.

Paul has been selected as a “Leading Lawyer” by the Law Bulletin Publishing Company and was named to Lawyers of Color's inaugural Nation's Best List which recognizes lawyers who have demonstrated a commitment to advancing diversity, equity and inclusion efforts in the legal profession. In 2020, he was selected as one of the Notable Minorities in Accounting, Consulting and Law by Crain's Chicago Business which features professionals who have overcome challenges and bias to rise to the top of their profession.

Background and Credentials

Paul's clients include Fortune 100 companies, elite universities, and cutting-edge startups. Since joining the firm in 1998, he has protected and defended the valued technological, engineering, and intellectual assets of his clients. Whether working with general counsel or an entrepreneur, a professor or a licensing professional, a research scientist or in-house IP counsel, Paul offers an un-paralleled depth of knowledge and expertise.

Today, Paul's practice is primarily focused on protecting client assets through prosecuting patents, counseling, post-grant review, and developing IP strategies. He also advises clients on challenging competitor patents through reexamination, IPR, PGR, and CBM proceedings, topics about which he has lectured at both client-exclusive and industry-wide CLEs. A good portion of his work over the last decade has been directed toward building licensable IP portfolios for startups and universities.

Paul's practice also includes considerable litigation experience wherein he has successfully represented clients at the CAFC and in district courts across the country, including successfully litigating through jury trial. Today, his role in litigation is more managerial: counseling clients on cases filed by both competitors and patent trolls and assisting with liability phases, while relying upon the deep bench of skilled and experienced litigation partners and associates to the day-to-day “heavy lifting.“ Paul is a firm believer in the team approach, finding the best resource in the firm for the project at hand.

Paul received his J.D. from the University of Michigan Law School in 1998. He received his M.S.E. in Electrical Engineering and his B.S.E. in Electrical Engineering, magna cum laude, both from the University of Michigan College of Engineering. His graduate research was performed at the National Science Foundation Center for Ultrafast Optical Science in Ann Arbor, Michigan.
