Valeo Wiper Systems v Robert Bosch France SAS and others

UPC_CFI_1963/2025, LD Paris, Order of 23 March 2026 [1]

This order, a full panel review of a the Judge-Rapporteur’s order rejecting a preliminary objection, adopts a broad interpretation of the requirement in Art 33(1)(b) that an infringement action against multiple defendants at the local division where one defendant has its principal place of business, “may be brought … only where the defendants have a commercial relationship and where the action relates to the same alleged infringement.”

Background

Valeo Wiper Systems sued a number of companies in the Robert Bosch group at the LD Paris for infringement of EP4144599.  The defendants included Robert Bosch France SAS, the “anchor defendant” giving the LD Paris jurisdiction under Art 33(1)(b)UPCA, the parent company Robert Bosch GmbH based in Germany, and a number of other subsidiaries based in Serbia, Belgium, and China.

The defendants challenged the jurisdiction of the LD Paris in relation to some of the defendants, arguing that the “commercial relationship” required by Art 33(1)(b) must be assessed in relation to the “anchor defendant”, and that the anchor defendant must have allegedly committed an infringing act with each other defendant. The defendants argued that these cumulative conditions could be satisfied by the parent company Robert Bosch GmbH, making a German local division competent, but could not apply to Robert Bosch France SAS which was itself a subsidiary.

Decisions

The LD Paris rejected these arguments.  It considered that the requisite commercial link should be assessed flexibly in order to avoid a proliferation of parallel proceedings and the risk of conflicting decisions, and thus that it was sufficient that all the defendants belong to the same group of companies and pursue the same objective. It was not necessary for every other defendant to have a special commercial relationship with the anchor defendant,and there was no basis in the wording of the provision to infer that UPC proceedings must always be brought in the local division corresponding to the parent company.

Moreover, the LD Paris interpreted “the same alleged infringement” to require only an identity of the infringed rights, i.e. the same patent, regardless of whether the allegedly infringing products have different trade names or different forms, provided that it is alleged that thesame patent claims are reproduced by each of the disputed products.  The LD Paris thus considered it immaterial that not all the defendants are concerned with strictly identical products, provided that these products are from the same range and are identified asinfringing the patent belonging to the claimant.

Significance

This ruling rejecting the preliminary objection affirms that patentees have significant flexibility in where to bring an infringement actionwhere infringement is carried out by a group of related companies.  It is not necessary to go to a local divisionin the country where the parent company is based – a local division in acountry where a subsidiary is based can also be competent in respect of all the defendants. Indeed related actions underdifferent patents can be brought at different local divisions, and here the claimant had asserted another patent (EP2671766) against the same companies in the Robert Bosch group at the LD Düsseldorf.

Recent Case Reports

UPC Court of appeal issues final decision, despite no finding on infringement at first instance
30 March 2026
In Rematec v Europe Forestry, the UPC Court of Appeal overturned the Mannheim Local Division’s revocation of the patent and, applying Article 75(1) UPCA, issued a final decision on both validity and infringement despite no infringement finding at first instance. The Court adopted a narrower, description‑led approach to claim interpretation, confirmed the patent’s validity, found infringement, and granted final remedies without referring the case back to the Court of First Instance.
Litigation insurance as security for costs
30 March 2026
In Syntorr v Arthrex, the UPC Court of Appeal clarified that while litigation insurance is not itself a form of security under Rule 158 RoP, it is a relevant factor when deciding whether security for costs should be ordered at all. By failing to consider the claimant’s insurance policy, the Munich Local Division wrongly exercised its discretion. The Court set aside the €2 million security order and confirmed that insurance can mitigate concerns about cost recoverability.
National law applies to claims for loss of profit if the events occurred before the UPC came into force
30 March 2026
In Fives v REEL, the Hamburg Local Division of the UPC dismissed a standalone damages action despite prior findings of infringement. Although the UPC was competent to assess damages, the court held that national law applied because the relevant events pre‑dated the UPC’s entry into force. Applying German law, the court found that the claimant had not proven causation or lost profit, highlighting the demanding evidentiary burden for price‑reduction damages claims and the importance of substantiating counterfactual tender outcomes.
