- Sommaire
There is no basis in the EPC for the substantiation of inventive step by way of disclaimer. This method may only be used by way of exception for avoiding anticipation, if the subject-matter of a claim cannot be restricted on the basis of the original disclosure in positive terms without unduly impairing its clarity and conciseness.
A hypothetical novelty attack in possible proceedings before a national court, unsupported by pleadings or evidence on the file before the EPO, is not a sufficient reason under the EPC for allowing a disclaimer.
