Ecovacs Robotics Co., Ltd. v.Roborock (HK) Limited

Luxembourg (LU) · UPC-000024

This appeal concerned the review of an ex parte order for inspection issued by the Local Division Düsseldorf. Ecovacs had applied for an order to inspect and preserve evidence of Roborock's robot vacuum cleaners exhibited at the IFA 2025 trade fair in Berlin, alleging potential infringement of EP 3 808 512. The Court of Appeal addressed the heightened duty of candour imposed on applicants seeking ex parte orders under R. 192.3 RoP, holding that omissions and distorted accounts of material facts relevant to the proportionality assessment cannot be remedied by later submissions in response to a request for review.

MERIL LIFE SCIENCES PVT LIMITED v.Respondent

Nordic Baltic Regional Division · UPC-000391

This case concerns European Patent EP 3 769 722, where Edwards Lifesciences Corporation sued several Meril entities for patent infringement, and the Defendants filed counterclaims for revocation. The Court of first instance found the patent invalid as granted but upheld it as amended, and found infringement of the amended patent, ordering the Defendants to bear the costs of the infringement proceedings and 75% of Edwards' costs in the revocation counterclaim proceedings. The Defendants sought rectification of the costs order, arguing the Court should have expressly ordered Edwards to bear 25% of the Defendants' costs in the counterclaim proceedings. The Court dismissed the rectification requests, holding that the chosen cost allocation was a valid and equitable distribution under Article 69 UPCA and the Rules of Procedure.

KIPA AB v.Respondent

Nordic Baltic Regional Division · UPC-001007

Meril Life Sciences Pvt Ltd., Meril GmbH v.Edwards Lifesciences Corporation

Luxembourg (LU) · UPC-001223

This appeal concerned the determination of which party is the prevailing party under Article 69(1) of the Agreement on a Unified Patent Court following the dismissal of a claim after the defendant submitted an injunction and commitment declaration. The dispute involved European Patent EP 3 763 331 relating to a crimping device for stent-based valve prostheses. The Court of Appeal held that when a defendant commits to comply with the plaintiff's requests after proceedings have been initiated, the plaintiff is generally considered the prevailing party, as the declaration itself implies that the plaintiff's requests have been fulfilled.

MERIL LIFE SCIENCES PVT LIMITED, INTERLUX, UAB, SMIS INTERNATIONAL OÜ, MERIL GMBH, SORMEDICA, UAB, VAB-LOGISTIK, UAB v.Respondent

Nordic Baltic Regional Division · UPC-001320

This is a procedural order from the Nordic-Baltic Regional Division of the Unified Patent Court concerning an infringement action regarding EP3769722. The Defendants (Meril entities and others) requested a stay of proceedings pending an EPO opposition decision, while the Claimant (Edwards Lifesciences Corporation) opposed the stay. The Court dismissed the request, holding that Rule 118.2(b) RoP applies only during oral procedure, a rapid EPO decision could not be expected, and the UPC could itself decide validity given the pending counterclaims for revocation.

SMIS INTERNATIONAL OÜ, VAB-LOGISTIK, UAB, MERIL LIFE SCIENCES PVT LIMITED, SORMEDICA, UAB, MERIL GMBH, INTERLUX, UAB v.Respondent

Nordic Baltic Regional Division · UPC-001319

This procedural order from the Nordic-Baltic Regional Division of the Unified Patent Court concerns a request by the Defendants (Meril Life Sciences and related entities) for the Claimant (Edwards Lifesciences Corporation) to provide security for legal costs in an infringement action concerning EP3769722. The Defendants argued that security was warranted because the Claimant is based in the United States, outside the EU, making enforcement of any cost order potentially difficult. The court dismissed the application, holding that the Claimant's location outside the EU and the lack of experience enforcing UPC orders in the US are not sufficient grounds for ordering security, and that the balance of interests favored the Claimant.
