Jay Erstling recently retired from Patterson Thuente IP, where he was Of Counsel. Jay served as an advisor to clients interested in all aspects of international patenting, including filing strategies, best PCT practices, foreign prosecution, country selection, working with foreign counsel, and foreign enforcement. Jay’s expertise in international patent law and practice comes from decades of experience in the international patent arena. Prior to joining Patterson Thuente, Jay was the Director of the Office of the PCT (the Patent Cooperation Treaty – the international patent filing system) at the World Intellectual Property Organization (WIPO, the UN specialized agency devoted to promoting and protecting intellectual property). As Director, Jay oversaw the administration of the worldwide PCT legal framework and led the PCT and all its member countries through a successful policy reform, expansion and modernization effort.

Jay’s career also has a lengthy academic side. He is a professor emeritus at Mitchell Hamline School of Law, where his teaching and research focused on international and comparative patent law, and he had stints as a visiting professor at several foreign law faculties, including Northwest University (Xibei Daxue) in X’ian, China, the National Law School of India in Bangalore, and Vytautas Magnus University in Kaunas, Lithuania. Jay was a Fulbright Scholar in Sri Lanka and in Cyprus, and he is the co-author of two books (The Practitioner’s Guide to the PCT, and International Patent Law and Policy) and lots of articles. He has also led more seminars and made more presentations on the PCT than he can count.

Jay looks forward to working with Fellows who are interested in learning about and exploring international protection for their medical devices.
