  Claimant:

  Wittenstein SE

  Defendant:

  Vestas Wind Systems A/S

  dismissed

  1. The requirement in Art. 138(1)(e) of the European Patent Convention that a European patent may be revoked if the proprietor is not entitled under Art. 60(1) should be interpreted as meaning that the proprietor does not have any rights to the patent. The burden of presentation and proof for facts establishing that the proprietor is not entitled lies with the claimant. It is therefore not sufficient for this ground of revocation to be successful that a claimant demonstrates that it has rights to parts of the subject-matter disclosed in a patent, e.g. as a co-inventor or the co-inventor’s successor in title. 2. Dependent claims are part of the patent and may be used as fall-back positions in revocation actions. At least in a stand-alone revocation action, where no infringement claim has been brought and it is therefore not yet clear which claims a patent holder may decide to rely on for what purpose, a claimant therefore may have a legitimate interest in having the validity of dependent claims assessed, even if the independent claim is deemed valid. Although the Court is not generally required to take a decision regarding dependent claims in such a situation, it should at least have the discretion to do so if considered appropriate based on the circumstances of the case.
