1.2.1 Revocation on substantive grounds 

If the opposition division is of the opinion that at least one ground for opposition as set out in Art. 100 prejudices the maintenance of the European patent, it will revoke the patent under Art. 101(2), first sentence. Similarly, if the opposition division is of the opinion that the patent as amended during the course of the opposition proceedings does not meet the requirements of the EPC, it will revoke the patent under Art. 101(3)(b). If one of the requests is to maintain the patent as granted and a further request is to maintain the patent as amended during opposition proceedings and neither of the requests meets the requirements of the EPC, then the patent is revoked under Art. 101, preferably citing Art. 101(2) and (3)(b).

For revocation because the patent proprietor has not agreed to the text, see D‑VI, 2.2 and D‑VIII, 1.2.5.
