beMatrix NV. v.Yaham Recience Technology Co., Ltd.

Düsseldorf (DE) Local Division · UPC_CFI_692/2026

This UPC decision involves a rectification of an earlier provisional measures order in the dispute between beMatrix NV. and Yaham Recience Technology Co., Ltd. The original application sought preliminary injunctions against alleged infringement of EP 3 757 442 B1, which covers display modules for temporary exhibition stands. The Court ultimately corrected a clerical error in its prior ruling, ensuring that the Defendant was properly ordered to cease and desist from infringing the patent. This highlights the procedural mechanisms available within the UPC for correcting administrative or drafting errors.

Leap Tools Inc. v.Wizart Inc.

Düsseldorf (DE) Local Division · UPC_CFI_541/2025

In this UPC decision, the Court of First Instance addressed a request by Wizart Inc. to impose security for legal costs on Leap Tools Inc., citing the latter's Canadian base and estimated revenue. The court ultimately rejected the motion, emphasizing that simply being non-EU or having moderate revenue is not enough to establish an undue burden of enforcement. Practitioners should note that applicants seeking security must provide detailed evidence regarding foreign law recognition and enforceability, rather than relying on general nationality arguments.

Canon Kabushiki Kaisha v.Katun Germany GmbH, Katun (E.D.C.) B.V., Katun Corporation, General Plastic Industrial Co., Ltd.

Düsseldorf (DE) Local Division · UPC_CFI_351/2024

While the core claims were dismissed, the ruling provided significant guidance on procedural fairness. The court held that defendants who use their websites to mislead the public about patent status may be compelled by Article 80 UPCA to publish the operative parts of the judgment themselves.

Düsseldorf (DE) Local Division · UPC_CFI_351/2024

In this procedural order, the UPC Local Division in Düsseldorf addressed a request from Canon Kabushiki Kaisha for simultaneous Japanese interpretation during oral proceedings. The Court ruled that allowing the Claimant to use an interpreter was appropriate to ensure equality of arms, given that some corporate representatives were not proficient in English. However, the Court denied the request for court-organized interpretation and held that the costs would not become part of the proceedings, emphasizing that such arrangements are generally not provided unless necessary or if the language is official.

Hewlett-Packard sought preliminary injunctions against Zhuhai ouguan Electronic regarding its fluid cartridge patents (EP 2 826 630 B1 and EP 3 530 469 B1). Although the court dismissed the application for provisional measures in most aspects, it issued a highly specific order.

Canon Kabushiki Kaisha v.Katun Germany GmbH a.o., Katun (E.D.C.) B.V., Katun Corporation, General Plastic Industrial Co., Ltd.

Düsseldorf (DE) Local Division · UPC_CFI_351/2024

Leap Tools Inc. v.Wizart Inc.

Düsseldorf (DE) Local Division · UPC_CFI_541/2025

In a procedural ruling, the UPC Local Division permitted Leap Tools Inc. to withdraw its infringement action against Wizart LLC (Defendant 2). The court found that because service of process had not been completed and Defendant 2 appeared non-existent or unserviceable, it lacked a legitimate interest in continuing the lawsuit. This decision highlights the procedural flexibility within the UPC regarding multi-defendant actions when one party becomes practically unreachable.

patent granted · Nov 11, 2025

Hewlett-Packard Development Company, L.P. v.Andreas Rentmeister e.K.; Shenzhen Moan Technology Co., Ltd.

Düsseldorf (DE) Local Division · UPC_CFI_515/2025

In a critical procedural ruling, the Düsseldorf Local Division addressed the challenges of serving foreign defendants in urgent UPC proceedings. The court ruled that if formal service attempts via international conventions stall or fail, and all other reasonable efforts have been exhausted, the steps taken by the applicant can be deemed sufficient for proper legal notice under Rule 275.2 RoP. This decision provides significant procedural relief to applicants facing unresponsive foreign jurisdictions in high-stakes IP litigation.

patent denied · Nov 6, 2025

Align Technology, Inc. v.Angelalign Technology Inc. a. o.

Düsseldorf (DE) Local Division · UPC_CFI_723/2025

In a procedural order concerning provisional measures, the UPC Local Division dismissed the Defendants' demand that Align Technology provide security for legal costs. The Defendants had argued that due to the Applicant being based in the United States, enforcement of any potential costs award would incur substantial and potentially non-reimbursable expenses. However, the Court found that the Defendants failed to meet their burden of proof, specifically by not providing evidence on the foreign law applicable for enforcement in the US. This decision reinforces the high evidentiary standard required when seeking security for costs within the UPC.

Düsseldorf (DE) Local Division · UPC_CFI_449/2025

In this UPC case concerning provisional measures against a Chinese defendant, the court addressed the critical issue of service failure under international conventions. Despite official notification from Chinese authorities that the company did not exist at the provided address, the Düsseldorf Local Division granted the applicant's request. The ruling established that if the applicant provides credible evidence verifying the accuracy of the registered address, prior attempts can be deemed good service, ensuring the applicant's urgent legal rights are protected.

Leap Tools Inc. v.Wizart Inc. and Wizart LLC

Düsseldorf (DE) Local Division · UPC_CFI_541/2025

After multiple failed attempts to locate the Defendants' current addresses, the Claimant successfully argued that good reason existed for alternative service.

Düsseldorf (DE) Local Division · UPC_CFI_807/2024

The Defendants challenged the Claimant's attempt to extend its argument from literal infringement to equivalence for additional features. The Panel ultimately upheld the initial order, confirming that expanding the equivalence argument does not fundamentally alter the nature or scope of the dispute. This ruling provides clarity on how the doctrine of equivalence can be applied procedurally within UPC case management.

This early decision sets the procedural framework for the complex dispute involving digital streaming technologies.

Eyesmatch Ltd v.Microsoft Corp.

Düsseldorf (DE) Local Division · App_36247/2025

This UPC decision confirms the procedural mechanism for withdrawing an infringement action when parties reach a settlement outside of court. Eyesmatch Ltd withdrew its claim against Microsoft Corp., and the Court formally closed the proceedings. The ruling highlights that mutual agreement between parties can supersede standard cost determination procedures, provided all necessary declarations are made.

This procedural order from the Düsseldorf Local Division addressed a Claimant's application to change its infringement claims regarding a swivel locking device for strollers (EP 1 905 615). The Claimant sought to modify claim language, primarily by altering how components were allocated between the 'seat' and the 'base' of the wheel bearing assembly. While the court found that the proposed extension of equivalence arguments was not fundamentally changing the targeted structure, it ultimately denied the application for leave to change the claim.

Düsseldorf (DE) Local Division · ORD_33920/2025

The court found that proceeding jointly was the most efficient approach, allowing both validity and infringement issues to be assessed under a single, uniform interpretation by the same judicial panel. This decision sets the framework for the full trial, which is yet to commence.
