Tobias Kaufmann, German and European Patent Attorney


What is it about?

The most common way of challenging granted European patents is filing an opposition with the European Patent Office within a 9 months window after grant, not least because an opposition is the only way to attack a “European bundle patent” as a whole. However, some opponents have expressed frustration with the EPO’s practice and the extensive examination of original support to the detriment of an exhaustive examination of inventive step. This webinar discusses whether German patent nullity proceedings, initiated after expiry of the opposition window, are a true alternative to oppositions before the EPO.

Johannes Heselberger and Tobias Kaufmann will address the following aspects:
•    General structure of EPO oppositions vs. German nullity proceedings
•    The different legal standards for invalidity 
•    Pros & Cons of the two procedures
•    Considerations for potential attackers and patentees

Are you looking to attack a European patent? Do you need to defend your patent before the EPO or in Germany?
