Summary: The Court of Appeal (UPC) reversed the Düsseldorf Local Division's first-instance decision, partially revoking EP 2 778 423 (claims 1–3, 5, and 11, to the extent not dependent on surviving claims) for lack of inventive step over prior art D5 combined with general technical knowledge, while maintaining claims 4, 6, 7, 9, and 10. As a consequence, the infringement action by Grundfos against Hefei was dismissed in full because the infringement allegations were based solely on the revoked claims and non-patentable auxiliary requests.
