About the event
Opposition matters is one of the key conferences for patent searchers and attorneys alike, offering participants direct access to EPO examiners and lawyers and European patent attorneys with many years of opposition experience. This year’s conference, which took place on 18 and 19 September 2025, focused on practical issues such as multiple auxiliary requests and opposition spread over several days but also targeted future developments such as AI in opposition and the link between opposition and the UPC. There was also a session on the biotech CRISPR cases but with a broader link to claiming priority.
