If the decision is not rectified within one month after receipt of the statement of grounds of the appeal, the appeal shall be remitted to the Boards of Appeal without delay, and without comment as to its merits. The purpose of interlocutory revision is to avoid that the Boards of Appeal are seized with appeals against decisions with regard to which the need of rectification has been recognized by the Office. However, the purpose of interlocutory revision is not to remove mistakes in decisions of the Office without changing the outcome of a case, but to grant the appellant the relief sought by him. Interlocutory revision is not available in inter partes proceedings. Likewise, interlocutory revision is not available where the time limit of one month following the receipt by the Office of the statement of grounds of appeal has expired.
Interlocutory revision requires a pending appeal.
Where the appeal has been withdrawn before the one month time limit available for interlocutory revision has expired and before a decision granting interlocutory revision has been taken, interlocutory revision is not available. Where interlocutory revision is available, the documents making up the appeal shall be transmitted by the Registrar of the Board of Appeal to the head of the department or division of the Office which has taken the decision. This applies also to any subsequent communication relating to the appeal. A copy of the appeal and any such communication shall be communicated to the Legal Department. Interlocutory revision may only be granted where the appeal is admissible and well-founded.
