American Wave Machines, Inc. v.Surftown GmbH a.o.
Procedural order from the Düsseldorf Local Division concerning EP 2 728 089 B1, addressing the Defendants' application for review under R. 333.1 RoP of a case management order that had dismissed their requests to extend time periods for filing a Rejoinder, a Reply to the Defence to the Counterclaim for Revocation, and a Defence to the Claimant's Application to amend the patent-in-suit. The court found the request for review admissible but unfounded, holding that the Defendants failed to demonstrate any hindrance or complication of legal defence warranting an extension, and that merely having less time than the opposing party does not constitute compelling reasons for extending statutory deadlines.
Hewlett-Packard Development Company, L.P. v.Andreas Rentmeister e.K. and Shenzhen Moan Technology Co., Ltd.
The Düsseldorf Local Division issued an order under Rule 275.2 of the Rules of Procedure declaring that the steps already taken to serve an application for provisional measures on Defendant 2 (Shenzhen Moan Technology Co., Ltd.) constituted good service. The Court found that formal service via the Hague Convention through the Chinese Central Authority had failed despite multiple inquiries, and that further delay was incompatible with the urgent nature of provisional measure proceedings.
Yangtze Memory Technologies Co., Ltd. v.Micron Technology, Inc. a. o.
This is a procedural order from the Düsseldorf Local Division concerning EP 3 850 660, in which Yangtze Memory Technologies Co., Ltd. filed three infringement actions against four Micron entities on 6 October 2025. Defendants 2 to 4 requested an extension of time periods for lodging preliminary objections and filing the statement of defence, citing the exceptionally large scope of the litigation campaign and the extensive technical evidence submitted by the Claimant. The Claimant objected, arguing that the technical reports had been known to the counterparties since 2024 and that global coordination did not justify delay. The Court granted the extension, setting the deadline for preliminary objections at 24 November 2025 for all Defendants and extending the deadline for the statement of defence and any counterclaim for revocation to 16 March 2026.
Align Technology, Inc. v.Angelalign Technology Inc. a. o.

When service via the Chinese Central Authority under the Hague Convention failed after three and a half months—with Chinese authorities claiming the defendant did not exist at the provided address—the Düsseldorf Local Division ordered that the steps already taken constituted good service under Rule 275.2 RoP, deeming service effective as of the date of the order.

Ona Patents SL v.Google Ireland Limited o.a.
Procedural order from the Düsseldorf Local Division concerning EP 2 263 098 B1, addressing the admissibility of the Claimant's unsolicited submission of 1 September 2025. The court admitted the translation of main requests and clarifications regarding direct infringement auxiliary requests, but rejected as inadmissible the new auxiliary requests concerning indirect infringement, finding that the Claimant failed to justify late filing under R. 36 RoP.
Wonderland Nurserygoods Co., Ltd. v.Cybex GmbH and Others
The Düsseldorf Local Division of the Unified Patent Court upheld a judge-rapporteur's order denying the claimant's application for leave to change its claim to add an auxiliary request asserting infringement by equivalence for additional patent features. The defendants had requested a panel review under R. 333 RoP, arguing the reasoning was disadvantageous to them. The panel found the review admissible but rejected it on the merits, confirming that extending the equivalence argument to features 1.9 and 1.10 did not alter the nature or scope of the dispute.
