Our analysis

Summary

By an order of 17 February 2025 issued after the interim conference (UPC_CFI_440/2023), the judge-rapporteur of the Paris Local Division closed the interim procedure in Seoul Viosys’s infringement action against Laser Components over EP 3 404 726, in which Photon Wave is an intervener. The main point is the value of the dispute, set at EUR 500,000 as declared by the claimant, because the intervener’s lower figure was not backed by accounting evidence. For practitioners, the order is a reminder that a challenge to the declared value must be documented.

Question

Should the value of the action be the EUR 500,000 declared by the claimant when filing, or the figure of no more than EUR 250,000 put forward by Photon Wave?

Decision

The judge-rapporteur kept EUR 500,000 for the time being: Photon Wave’s assertions were not supported by accounting documents and, under Rule 370.6, the estimate reflects the objective interest pursued by the party bringing the action. The order also records that Laser Components, although summoned, did not attend and was told that a decision by default would be given against it, that costs and damages will be dealt with in separate proceedings, and it sets the oral hearing for 13 March 2025, from 9:00 to 13:00, with speaking time allocated between the parties.

Key points for practice

• A party disputing the declared value of the action must produce accounting evidence. Otherwise the amount stated at filing stands.
• The interim conference is also used to frame the hearing: issues in dispute, simultaneous interpretation arranged and paid for by each party (Rule 109.4), and no need for a witness to attend where only the inferences drawn from the written statement are in dispute.
