Under R. 99(3) EPC Part III of the Implementing Regulations applies mutatis mutandis to the notice of appeal, the statement of grounds and the documents filed in appeal proceedings.

R. 99(3) EPC and R. 41(2)(h) EPC together make it clear that a notice of appeal must be signed by the appellant or his representative, but not that every single document in the notice has to be signed or that the signature has to be appended at a particular place or page. In T 783/08, the debit order had been part of the notice of appeal, so the board held that the signature on it fulfilled the EPC requirements in question. The appeal had therefore been validly filed.
