The revocation of patent right refers to the patent that has been approved, and it has been declared revoked by the court or patent office because it has not been implemented for a certain period of time. The revocation of patent right is a kind of sanction measure for the patentee not to implement his patent. The revocation of a patent has no retrospective effect, that is, it does not go back to the time when the patent right was granted. In some countries, compulsory license is a prerequisite for patent revocation, that is, when compulsory license is still insufficient to prevent patent abuse, the patent can be revoked, but most developing countries do not take compulsory license as a prerequisite for patent revocation.
