Joint International Symposium on U.S. & European Patent Practice – Fall 2022

Schedule : at Online & In-Person in Austin, TX

The Oblon and Maiwald firms are pleased to announce the Fall 2022 Joint Symposium on US and European Patent Practice – Important Aspects for Practitioners. This will take place at the Marriott in Austin, TX and simultaneously online.

At this joint international symposium, you will learn recent developments and current aspects of IP practice in the U.S. and Europe. With the upcoming start of the Unitary Patent system and the Unified Patent Court (UPC) in Europe, new opportunities for applicants and patent owners will become available. Patent-eligible subject matter, written description, and other central issues in U.S. and European patent law continue to evolve. And assignments, while deceptively simple, still create traps for the unwary.

Key Takeaways

You will learn current developments in patent practice from the U.S. and European perspectives. Applicants and patent owners need to be aware of upcoming additional options and peculiarities of the patent systems in the U.S. and Europe, which do not always align. Hear strategies for navigating through the most recent changes including the following topics:

1. Unitary Patent and Unified Patent Court in EP - are you prepared?

2. Eligible subject matter - an update from a U.S. perspective

3. Priority - EP perspectives

4. Assignment issues and requests

5. Support, amendments, and enablement - U.S. perspectives

6. Support, amendments, and enablement - EP perspectives

Texas/Virginia CLE credit will be requested

Oblon speakers will include David Longo, James Love, and Andrew Ollis.
