1.1 General remarks 

The opposition division has to take a final decision on the opposition, by revoking the European patent or rejecting the opposition or ruling that the European patent is to be maintained as amended. If the only admissible opposition or all the admissible oppositions are withdrawn and the opposition division takes the view that as the case stands there is no reason for the Office to continue the proceedings of its own motion, the proceedings are closed by means of a formal decision (Rule 84(2), second sentence).
