Board: 3.3.03
Headnote: -
Relevant legal provisions:
European Patent Convention 1973 Art 84
Keywords: Clarity of functional features - undue burden for reduction to practice
Catchwords:

I. The term "clarity" in Article 84 EPC refers to the practical meaning of the language of the patent claims. Claims with functional features which do not enable the skilled person to carry out the invention in the light of the disclosure and on the basis of common general knowledge do not meet the requirement of clarity according to Article 84 EPC (point 3.1.3 (v) and 3.2.3).

II. A claim combining functional definitions limited to features, which a skilled person would have no difficulty in determining on the basis of common general knowledge, and a structural definition of the essential contribution of the Applicant is not objectionable under Article 84 EPC (point 3.3.2).
