Professor Jay Erstling

The PCT (Patent Cooperation Treaty) is the heart of the international patent system and an essential tool used by patent attorneys worldwide. But it is complex and difficult to master, so “The Practitioner’s Guide to the PCT” not only contains a clear and logical explanation of the PCT framework, it also provides practitioners with strategies and tips so that they can make most effective use of the system.

Before joining the William Mitchell faculty, Erstling was director of the Office of the PCT in Geneva, Switzerland, which is responsible for administering the PCT system worldwide. His courses at Mitchell include Comparative and International Patent Law.

Erstling’s co-authors on the book are Samson Helfgott, a noted international patent attorney and PCT expert, and David Reed, the retired director of international patenting at Proctor and Gamble, a major PCT user.  The three authors collectively have almost 100 years of PCT experience. Copies of the book are available at
