Headnote: I.The patent claims must clearly define subject-matter for which protection is sought (Article 84 EPC). This requirement may be fulfilled in a claim to a product when the characteristics of the product are specified by parameters related to the physical structure of the product, provided that those parameters can be clearly and reliably determined by objective procedures which are usual in the art.
II. In such a product claim, it suffices to state the physical properties of the product in terms of parameters, since it is not mandatory to give instructions in the claim itself as to how the product is to be obtained. The description must fulfil Article 83 EPC and thus enable the person skilled in the art to obtain the claimed product therein described.
Relevant legal provisions:
European Patent Convention 1973 Art 84
European Patent Convention 1973 Art 52(1)
European Patent Convention 1973 Art 56
Keywords: Definition of product by a product claim containing parameters
