Valeo Systemes d’Essuyage initiated an infringement action against multiple Bosch entities concerning EP 2671766 in the Unified Patent Court (UPC), at the Paris division. Bosch challenged the Paris division's jurisdiction and the language of the proceedings. The initial court upheld Bosch's preliminary objection, redirecting the case to the Düsseldorf division, with proceedings in English. Valeo appealed, seeking to establish Paris's competence and proceedings in French. The Court of Appeal reviewed the admissibility of Valeo's appeal and invited Bosch to comment on this matter before proceeding. Meanwhile, the deadlines for Bosch's defense were suspended.
