PAPST LICENSING GmbH & Co. KG v.Europäisches Patentamt (EPA)

Papst Licensing appealed a decision of the Paris Central Division of the Unified Patent Court that had upheld the European Patent Office's rejection of its request for unitary effect for European patent EP 3 327 608. The patent, derived from a divisional application of a Euro-PCT application filed in 2005, did not include Malta among its designated states because Malta acceded to the European Patent Convention only in 2007. The Court of Appeal held that Article 3(1) of Regulation 1257/2012 cannot be interpreted to allow registration of unitary effect for a granted European patent that does not include the designation of one of the participating Member States, and accordingly rejected the appeal, with each party bearing its own costs.
