The EU Unified Patent Court (UPC) announced a launch date of April 1, 2023, however, the announced date should be regarded as a statement of intent for it could change. The launch timing has been the subject of various delays and setbacks, several due to unresolved legal issues. The UPC has also published an almost final list of judges. German Federal Court of Justice Judge Klaus Grabinski, who played a key role in drafting the UPC Rules of Procedure, will head the UPC. The majority of UPC judges will only be engaged with their UPC activities part-time (about 50% or 20% of their total work commitment).

The UPC judges are set to receive special training starting in March 2023, only one month prior to the announced launch date of the UPC, leading many to doubt that the April 1 date will be met. Once the new court is operational, owners of European patents will be able to litigate patent disputes across most EU Member States in a single proceeding, eliminating the need to proceed on a country-by-country basis.

Assuming the announced launch date is maintained, the “sunrise period” before the UPC becomes fully operational will commence on January 1, 2023. This sunrise period will last for three months, during which patent owners that do not wish for their existing European patents to be subject to UPC jurisdiction may opt out of such jurisdiction by filing a formal notification to that effect. The European Patent Office has also announced that during the sunrise period, European patent applicants whose applications are ready for grant will, if they wish, be able to delay the formal grant of the application until the UPC becomes operational so that unitary patent protection can be obtained.

The UPC has issued an implementation roadmap for events leading up to the entry into force of the UPC Agreement, with the court opening its doors and starting to receive cases as of April 1, 2023.
