1.2.5 Revocation of the patent in the event that the patent proprietor no longer wishes the patent to be maintained as granted 

If patent proprietors state that they no longer approve the text in which the patent was granted and do not submit an amended text, the patent must be revoked pursuant to Art. 101 (see T 203/14 and T 2405/12). This also applies when the patent proprietor requests the patent to be revoked.

If patent proprietors unambiguously declare to the EPO the surrender (or abandonment or renunciation) of the patent, this is interpreted as equivalent to a request that the patent be revoked (see T 237/86). If the request of the patent proprietors is not unambiguous, they are given the opportunity to request that the patent be revoked or to declare that they no longer approve of the patent being maintained as granted. This results in the patent being revoked.
