Our analysis

Summary

In an order of 30 April 2026 in the joined proceedings UPC_CFI_351/2024 and UPC_CFI_595/2024, the judge-rapporteur of the Düsseldorf Local Division dismisses the confidentiality application filed by Katun and General Plastic after the decision on the merits of 11 February 2026, concerning the information they must communicate to Canon (EP 3 686 683). The order confirms that protection for information to be communicated under Article 67 UPCA must be sought during the merits proceedings where the need is foreseeable.

Question

Can an application under Rule 262A RoP concerning information to be communicated under the merits decision be filed after that decision and restrict the use of that information?

Decision

Rule 262A RoP applies at least mutatis mutandis to such information (paragraphs 13 to 15). But where the defendant can reasonably foresee that the decision will require it to disclose confidential information, the application must be made during the merits proceedings. That was the case here, since the information concerned matched Canon’s requests exactly, and no reason was given for the delay (paragraphs 16 to 19). In any event, the use restriction sought would curtail the claimant’s right to information: that substantive issue belongs to the merits proceedings and cannot alter the operative part at the enforcement stage (paragraphs 20 to 22).
