After a patent right is granted and announced by the Patent Administration Department of the State Council, if any unit or individual believes that the grant of the patent right does not comply with the provisions of the Patent Law, it may request the Patent Reexamination Board to declare the patent right invalid.

Patent invalidity means that after the patent right is granted, it is found that it does not meet the conditions for granting patent rights in the Patent Law and its implementing regulations, and the patent reexamination board confirms and declares it invalid. A patent right declared invalid is deemed to have ceased to exist from the beginning.
