beMatrix NV v.Yaham Recience Technology Co., Ltd.
beMatrix NV, the proprietor of European Patent No. 3 757 442 B1 concerning a display module for temporary exhibition stands, applied for provisional measures against Yaham Recience Technology Co., Ltd. before the Düsseldorf Local Division, alleging that Yaham's "Sytaq RA" modular LED display system infringed the patent. After Yaham's CEO declined to cooperate when approached at the EuroShop trade fair in Düsseldorf, the court granted the preliminary injunction ex parte. The court subsequently issued a rectification order on the same day to correct a clerical error that had mistakenly named the Applicant instead of the Defendant in the operative paragraph.
Leap Tools Inc. v.Wizart Inc.
The Düsseldorf Local Division dismissed the Defendant's request for security for legal costs under R. 158 RoP in proceedings concerning EP 3 859 566. The Defendant, Wizart Inc., sought at least EUR 300,000 in security, arguing that the Claimant, Leap Tools Inc., is a Canadian company with no UPC presence and limited annual revenue. The Court held that the Defendant failed to meet its burden of substantiation, as it neither addressed applicable Canadian law regarding enforcement of foreign judgments nor demonstrated that the Claimant's financial position raised legitimate concerns about recoverability of costs.
Canon Kabushiki Kaisha v.Katun Germany GmbH a.o.
Canon Kabushiki Kaisha sued Katun Germany GmbH, Katun (E.D.C.) B.V., Katun Corporation, and General Plastic Industrial Co., Ltd. for infringement of European Patent EP 3 686 683 B1, which relates to a developer replenishing container and system. The Düsseldorf Local Division found that the defendants' toner bottles infringed the patent, dismissed the defendants' counterclaim for revocation, and ordered injunctive relief, recall and destruction of infringing products, damages, and publication of the operative part of the decision on the defendants' websites.
Hewlett-Packard Development Company, L.P. v.Andreas Rentmeister e.K. and Shenzhen Moan Technology Co., Ltd.
This procedural order from the Düsseldorf Local Division concerns the service of a preliminary injunction order dated 19 December 2025 on Defendant 2, Shenzhen Moan Technology Co., Ltd., a Chinese-based company.

Hewlett-Packard Development Company, L.P. v.Zhuhai ouguan Electronic Technology Co., Ltd and Andreas Rentmeister e.K.

The Applicant, Hewlett-Packard Development Company, L.P., had sought provisional measures against the Defendants, but service on the China-based Defendant 1. proved impossible through the Chinese Central Authority, which certified that no such company existed at the address provided. The Court ordered that publication of the preliminary injunction order on the Court's website, with the names of the parties and file number, constitutes good service on Defendant 1. pursuant to Rule 275.2 RoP.
Canon Kabushiki Kaisha v.Katun Germany GmbH and Others
Canon Kabushiki Kaisha, a Japanese claimant in a patent infringement action before the Düsseldorf Local Division, requested simultaneous interpretation from English into Japanese during the oral hearing. The Defendants did not object to Canon engaging an interpreter at its own expense but opposed court-organised interpretation and associated costs. The court applied a two-stage test and held that while allowing simultaneous interpretation was appropriate, the costs should not become costs of the proceedings, as Japanese is neither an official language of a Contracting Member State nor of the Local Division.
Hewlett-Packard Development Company, L.P. v.Andreas Rentmeister e.K. and Shenzhen Moan Technology Co., Ltd.
Hewlett-Packard Development Company, L.P. sought provisional measures against Andreas Rentmeister e.K. and Shenzhen Moan Technology Co., Ltd. for alleged infringement of EP 3 835 965 B1, a patent relating to logic circuitry for replaceable print apparatus components. The Düsseldorf Local Division granted a preliminary injunction against both defendants, with Defendant 1 having reached a settlement and not defending against most motions, and Defendant 2 having failed to file any objection despite being served through the Chinese Central Authority.

Canon Kabushiki Kaisha v.Katun Germany GmbH & Others
The Düsseldorf Local Division issued an order on a Rule 36 RoP application by Canon Kabushiki Kaisha seeking permission to submit further written pleadings in its infringement action concerning EP 3 686 683 B1 against Katun Germany GmbH and other Katun entities plus General Plastic Industrial Co., Ltd. The court permitted Canon to file the EPO Opposition Division's preliminary opinion and a summary of its reasoning, but rejected the request to introduce evidence from an additional test purchase conducted in October 2024, finding the submission unjustifiably delayed and essentially redundant. The written procedure was deemed closed upon expiry of the filing deadline.
Leap Tools Inc. v.Wizart Inc. and Wizart LLC
Leap Tools Inc. filed an infringement action concerning EP 3 859 566 against Wizart Inc. and Wizart LLC before the Düsseldorf Local Division. After difficulties in serving Wizart LLC and representations from Wizart Inc. that Wizart LLC was a non-existent company, the Claimant applied to withdraw the action against Wizart LLC. The Court permitted the partial withdrawal, finding that Wizart LLC had no legitimate interest in a decision on the merits since service had not yet been completed.
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.
Align Technology, Inc. v.Angelalign Technology Inc. a. o.
The Düsseldorf Local Division dismissed the Defendants' request for security for legal costs in provisional measures proceedings concerning European Patent EP 4 346 690 B1. The court held that the Defendants failed to meet their burden of substantiation regarding the alleged difficulty of enforcing a costs order in the United States, as their reliance on a prior Munich Local Division order was insufficient to establish facts specific to this case.
Hewlett-Packard Development Company, L.P. v.Andreas Rentmeister e.K. and Shenzhen Moan Technology Co., Ltd.
Hewlett-Packard Development Company, L.P. filed an application for provisional measures against Andreas Rentmeister e.K. and Shenzhen Moan Technology Co., Ltd. for alleged infringement of EP 3 835 965 B1, which relates to logic circuitry for replaceable print apparatus components. Defendant 1 reached a settlement with HP and agreed not to defend against the main motions, while service to Defendant 2 in China had not been completed. The Düsseldorf Local Division issued an order by default against Defendant 1, granting the preliminary injunction, information orders, and penalty payments, while reserving decision on costs and the application against Defendant 2.
Hewlett-Packard Development Company, L.P. v.Zhuhai ouguan Electronic Technology Co., Ltd.

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.
Leap Tools Inc. v.Wizart Inc. & Wizart LLC
Procedural order from the Düsseldorf Local Division concerning EP 3 859 566, in which the court permitted alternative service of the Statement of claim on Defendant 2 (Wizart LLC) under Rule 275 of the Rules of Procedure.

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.
