Sufficiency of disclosure

According to article 83 European Patent Convention (EPC): ‘The European patent application shall disclose the invention in a manner sufficiently clear and complete for it to be carried out by a person skilled in the art.’ For the disclosure to be sufficient at least one way of carrying out the invention should be disclosed in the description such that it is apparent to the skilled person how to put the invention into practice. Lack of sufficiency is a ground for revocation of a European patent in opposition proceedings at the European Patent Office, and for invalidation by national courts.
