In proceedings before the European Patent Office, documents may be filed by delivery by hand, by postal services or by means of electronic communication. The President of the European Patent Office shall lay down the details and conditions and, where appropriate, any special formal or technical requirements for the filing of documents. In particular, he may specify that confirmation must be supplied. If such confirmation is not supplied in due time, the European patent application shall be refused; documents filed subsequently shall be deemed not to have been received.
Where the Convention provides that a document must be signed, the authenticity of the document may be confirmed by handwritten signature or other appropriate means the use of which has been permitted by the President of the European Patent Office. A document authenticated by such other means shall be deemed to meet the legal requirements of signature in the same way as a document bearing a handwritten signature which has been filed in paper form.
