Düsseldorf Local Division final decision in infringement action (with revocation counterclaim) concerning a pump patent (EP 2 778 423 B1), by Grundfos against a Chinese manufacturer (Hefei Xinhu Canned Motor Pump). The court found infringement, granted an injunction, ordered accounting/information, recall from distribution channels, and declared liability for damages from 28 February 2018. The revocation counterclaim was dismissed. Defendant bears all costs. The court addressed the admissibility of new prior art raised for the first time in the defendant's rejoinder to the revocation counterclaim, holding that such new attacks require a convincing explanation of why they could not have been included earlier.
