The Unified Patent Court (UPC) Opens Its Doors: A Historic Shift for European Patent Litigation and Translation

On June 1, 2023, the Agreement on a Unified Patent Court (UPCA) officially entered into force alongside the Unitary Patent, creating a single supranational court for patent disputes across participating EU Member States and establishing strict litigation translation timelines.

June 1, 2023: A New Era for European Intellectual Property

After decades of intergovernmental negotiations, the Unified Patent Court (UPC) officially opened for business on June 1, 2023, with its Central Division headquartered in Paris (and specialized sections in Munich and Milan) alongside local and regional divisions across participating EU Member States. Simultaneously, the European Patent Office began granting European patents with unitary effect. While the Unitary Patent simplifies post-grant validation across participating states, cross-border infringement and revocation actions before the UPC introduce compressed procedural deadlines for legal and technical translation.

Language of Proceedings and Evidentiary Translation under the UPC Rules of Procedure

Under the UPC Agreement and Rules of Procedure, local divisions may conduct proceedings in the official national language of the hosting state or in an official EPO language (English, French, or German) designated by that division. When an infringement action is brought, the defendant has the statutory right to request a full translation of the patent specification and statement of claim into the language of the Member State where the alleged infringement occurred or where the defendant is domiciled. Given the UPC’s strict front-loaded procedural schedule—where written defenses and revocation counterclaims are due within three months—law firms rely on specialized IP translation teams capable of delivering certified patent translations under tight deadlines.
