Comparison of opposition proceedings at the EPO andrevocation actions at the UPC – advantages and disadvantages

Since the introduction of the Unified Patent Court (UPC) in June 2023, a new system for central attacking the validity of and thereby to nullify a European Patent has been introduced. If a European patent of concern is an EU Unitary Patent, or if a classically validated European patent was not opted out from the competence of the UPC, a central revocation action under the UPC now exists in parallel to an opposition before the European Patent Office (EPO). Therefore, the question arises: what are the pros and cons of challenging the validity either before the EPO or before the UPC? The present report provides some guidance and discusses the main advantages and disadvantages of each system – which eventually is a matter of strategic considerations whether and which advantage may prevail – be it costs, timing, speed of proceedings, and possibly other issues.

Chances and Risks of the New European Unitary Patentand New Unified Patent Court – Part 3

Opposition proceedings before the European Patent Office (EPO) are an attractive forum for challenging patents; the procedure is virtually unrivaled worldwide in terms of value for money. The process is simple, streamlined and relatively inexpensive. The practice is well tested. However, there are restrictions and drawbacks – for example, a deadline of nine months after the grant date for submission, the long duration of the opposition and appeal proceedings, and strict rules for admitting evidence submitted late.

Chances and Risks of the New European Unitary Patentand New Unified Patent Court – Part 2

During a seven-years transition phase, the jurisdiction of the future Unified Patent Court (UPC) can be declared inapplicable, by way of an opt-out request by the IP right holder, to a pending European patent application (“EP application”), to a granted European patent (“EP”), or to a supplementary protection certificate (“SPC”). This possibility was introduced to build confidence by users on the long run. If opted-out, disputes will then continue to be handled by national courts on a country-by-country basis. Once a European patent has been opted out, it is excluded from the jurisdiction of the UPC for its entire life.
