Case Law


IPPT20240227, UPC CFI, LD Paris, Seoul Viosys v Laser Components
No change of language of proceedings from French to the language of the patent (English) rejected (Rule 322 RoP, Article 49 UPCA). The plaintiff, a Korean company, chose to bring its action in French, which is respectful of the rights of the defendant, a French company established in France. Neither the nationality of the representative of one of the parties, nor the nationality of the company intervening in the proceedings, which it has not been proven at this stage will participate in the proceedings, constitute serious grounds, either for reasons of convenience or for reasons of fairness, for proposing a change in the language of proceedings to the parties. 


IPPT20231103, UPC CFI, LD Munich, Amgen v Sanofi-Aventis

Change of the language of the proceedings from German to English, the language of the patent, subject to the agreement of both parties and the other members of the panel (Rule 322 RoParticle 49 UPCA).
