J A Kemp Webinar: Opposition Practice at the EPO

12 March 2020

This webinar is now available on-demand. Click here to access the recording.

Opposition practice at the EPO continues to develop, particularly in view of the changing procedure before the Boards of Appeal. This webinar makes use of the significant experience of J A Kemp’s attorneys, both in attacking patents in opposition at the EPO, as well as defending cases which have been opposed. We will consider opposition practice, including how to set up an attacking opposition. We will also highlight strategies for defence, including setting up the case in prosecution and formulating a strategy for amendment during opposition.

Topics include:

  • Grounds of opposition and approaches to setting up an opposition statement
  • Good defence starts in prosecution
  • Claim amendments  - auxiliary requests in opposition
  • Overall strategies for attack and defence, to maintain flexibility on appeal
  • The role of experiments: what supporting data can usefully be filed, and when should it be provided.
  • Oral proceedings at the EPO
