Our analysis

Summary

By order of 26 November 2025, the judge-rapporteur of the Brussels Local Division stays Yealink’s preliminary objection, which challenges the division’s territorial competence under Art. 33(1)(a) UPCA in Barco’s infringement action on EP 3 732 827, until the Court of Appeal decides UPC_CoA_317/2025. That appeal, brought against the provisional measures order of 21 March 2025, concerns the same competence issue. The order shows how a division coordinates a preliminary objection in the main action with a pending appeal in interim proceedings.

Question

Should the preliminary objection be decided while the same territorial competence issue is pending before the Court of Appeal in the provisional measures proceedings?

Decision

Since the parties agree that the objection raises the same issues as Yealink’s cross-appeal, and both ask for a stay, the judge-rapporteur grants it (paragraphs 8 and 9). Yealink is to comment within five working days of the Court of Appeal’s decision, and Barco within five working days thereafter, so that a ruling can if possible be given before the time limit for the Statement of Defence expires (paragraph 10). If no appeal decision has issued by 22 December 2025, the parties must comment by 29 December 2025 on an extension of that time limit (paragraph 11).

Key points for practice

Where territorial competence is already before the Court of Appeal in provisional measures proceedings, a preliminary objection in the main action may be stayed pending that decision, with a tight timetable for comments.
