Case Law

IPPT20240827, UPC CFI, LD Munich, Hand Held Products v Scandit

Preliminary injunction for indirect infringement (Article 62 UPCA, R. 211.2 RoP). Validity. Burden of proof. It is the task of the defendant in the present case to present arguments based on the prior art that make the legal validity of the patent in dispute appear insufficiently secure (Article 54 UPCA). Due to the summary nature of the examination of the legal validity in proceedings for the adoption of interim measures, the number of arguments raised against the legal validity must generally be reduced to the best three from the defendant's point of view. The background to this is that while a summary judgement on questions of fact is conceivable, a summary examination of questions of law is not. 

IPPT20240731, UPC CFI, LD The Hague, Amycel
Novelty arguments rejected (Article 54 EPC, Article 54 UPCA). Both novelty arguments raised by Defendant are unsubstantiated whereas the burden of presentation and proof for facts concerning the lack of validity of the patent and other circumstances allegedly supporting the Defendant's position lies with the Defendant. 

IPPT20240703, UPC CFI, LD Düsseldorf, Kaldewei v Bette
Burden of proof invalidity (article 54 UPCA). The burden of presentation and proof for facts relating to an attack on the novelty and/or inventive step of the patent in dispute lies with the defendant. 

IPPT20240619, UPC CFI, LD The Hague, Abbott v Sibio – EP283
Preliminary measures denied. No sufficient degree of certainty that patent is valid (Article 62(4) UPCA; Rule 211(2) RoP). The burden of presentation and proof with regard to the facts from which the lack of validity of the patent is derived and other circumstances favourable to the invalidity or revocation lies with the opponent (Art. 54 UPCA). 

IPPT20240408, UPC CFI, LD Milan, PMA v AWM
No access to written report and any other outcome of the measures to inspect premises and to preserve evidence and revocation of the measures to preserve evidence because applicant did not timely start proceedings on the merits (Article 60(9) UPCA, Rule 198 RoP, Rule 9(4) RoP). Restitution of all evidence gathered through the execution of the revoked measures is to take place from 05.06.2024 on, unless the Court of Appeal decides otherwise (Article 74 UPCA, Rule 223 RoP). It is quite clear that an appeal could not be effective if this Court’s order for the return of the evidence gathered were given immediate effect. Damages claim dismissed (Article 60(9) UPCA, Article 54 UPCA, Rule 198(2) RoP). AWM and Schnell failed to allege, identify, and prove what concrete damage would have been caused by the enforcement of the measures, resulting in the dismissal of the claim, since – as provided for in Art. 54 UPCA – the burden of the proof of facts lies with the party relying on those facts.
