Summary

By an order of 26 August 2025 (UPC_CFI_361/2025, ORD_34798/2025), the judge-rapporteur of the Paris Local Division, at the Vivo companies’ request, clarified that the time limits for the preliminary objection and the statement of defence in Sun Patent Trust’s infringement action (EP 3 852 468) run from the confidentiality order of 31 July 2025, despite the appeal against it, and granted an extension limited to three weeks: any preliminary objection by 28 September 2025 and the statement of defence by 28 November 2025.

Question

Does an appeal against a confidentiality order, concerning access by certain individuals to highly confidential FRAND-related information, postpone the start of the defence time limits, and does it justify an extension?

Decision

No, save for a limited extension. The provisional order of 3 July 2025 had made the final order, issued on 31 July 2025, the starting point, and the defendants’ representatives had access to the unredacted file from 3 July. Under Rule 220.2 an appeal has no suspensive effect unless the Court of Appeal decides otherwise under Rule 223, it rejected the application for suspensive effect as inadmissible on 15 August 2025 and as unfounded on 25 August 2025 (UPC_CoA_759/2025). Extensions under Rule 9.3(a) are granted strictly: the appeal concerns only the highly confidential FRAND-related information, not the preliminary objection, validity or the alleged infringing acts. Vivo’s voluntary postponement of access for three individuals justifies three weeks.

Key points for practice

Practical point: a dispute over the confidentiality club does not freeze the defence time limits, the party concerned should promptly seek a targeted extension.
