In addition to the documents referred to in A‑VIII, 3.1 above, certain documents forming part of the application must be signed. These documents include the request for grant, the designation of the inventor and, where applicable, the authorisation of a representative. In the case of electronic filing of a European patent application, a facsimile image of the signer's handwritten signature, a text-string signature or an enhanced electronic signature may be used to sign the aforementioned documents (Art. 7 of the Decision of the President of the EPO dated 10 November 2015, OJ EPO 2015, A91).
With the exception of the authorisation of a representative, the documents may be signed by an appointed representative instead of the applicant.
