Under what circumstances can a patent be declared invalid, and what are the consequences of the patent being declared invalid?

After the patent right has been granted and announced by the patent administration department of the State Council, any unit or individual may request the Patent Reexamination Board to declare the patent right invalid if it considers that the grant of the patent right is not in conformity with the provisions of the Patent Law.

Patent invalidation refers to the act that after the patent right is granted, it is found that it does not meet the conditions for granting the patent right in the Patent Law and its implementing rules, and it is declared invalid after reexamination and confirmation by the Patent Reexamination Board. An invalid patent right is regarded as nonexistent from the beginning.
