EPO oppositions remain one of the most powerful tools for challenging the validity of a European patent after grant. They offer a centralised and cost-effective route to attack any European patent with effect across all 40 EPC contracting states.

In this webinar, J A Kemp’s experienced European patent attorneys will provide practical insights into EPO opposition practice and potential procedural pitfalls to guard against or exploit, drawing on their extensive experience in both attacking and defending patents before the EPO.

Topics covered include:

The initial opposition and defence – how to best set up your case
Amendments and auxiliary requests – how many is too many?
Adding to your case – when to do it and navigating the “late-filed” problem
Strategies for maximising flexibility on appeal
Why a good defence starts during prosecution
Whether you are considering opposing a competitor’s patent, defending your own portfolio, or handling applications with a future opposition risk, this webinar will provide practical guidance on navigating EPO opposition proceedings with confidence.
