With the exception of annexes, any documents filed after filing of the European patent application must be signed. In online filings the signature may be in the form of a facsimile, text string or enhanced electronic signature. In paper filings it may be a handwritten signature or a reproduction of the filer's signature (on faxes). The name and position of that person must be clear from the signature. Following the revised decision of the President of the EPO which entered into force on 16 November 2015, the use of an enhanced electronic signature is no longer mandatory in appeal proceedings. Article 8(2) of the decision dated February 2009 on the electronic filing of documents (OJ 2009, 182) has been deleted in the revised version.
