Fisher & Paykel Healthcare Limited v.Flexicare (Group) Limited
This procedural order concerns a revocation action regarding European Patent EP4185356 before the Court of First Instance of the Unified Patent Court, Central Division Milan.

The Local Division Brussels dismissed the Preliminary Objection, holding that the UPC has jurisdiction over all national designations of the European patent when at least one defendant is rightfully sued before the UPC, and that the substantive assessment of infringement in those territories belongs to the merits stage.
