EIP Amar webinar - Prepare for the UP and UPC

Proceedings before the UPC Central Division must be conducted in the language in which the patent was granted. There is no legal basis to change that language. In a revocation action concerning a German-language patent, the Paris Central Division rejected a request to switch the language of proceedings to English, and also rejected a subsidiary request to allow written submissions in English and hold the hearing in English, holding that Article 49(6) UPCA permits no derogation and reflects a deliberate legislative choice.

This appeal judgment clarifies that Rule 190 orders to produce evidence require three cumulative conditions: specificity, necessity and proportionality, and cannot be used for fishing expeditions. The Court of Appeal confirmed that first instance judges enjoy a broad margin of discretion when assessing such requests, and upheld the order requiring production of two fabric samples for ballistic testing. Both the appeal and the cross-appeal were dismissed.

The Court of Appeal provided guidance on their approach to assessing added subject matter, highlighting that the technical effect underlying the invention and how the claimed and unclaimed features contribute thereto is central to the analysis.
