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 a patent proprietor states that they no longer approve the text in which the patent was granted and does 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 that the patent be revoked.

If the patent proprietor unambiguously declares to the EPO that they surrender (or abandon or renounce) their patent, this is interpreted as equivalent to a request for the patent's revocation (see T 237/86). If the request is not unambiguous, the patent proprietor is given the opportunity to request the patent's revocation or to declare that they no longer approve of the patent being maintained as granted. This results in the patent being revoked.
