What is invalid patent right?

Legal analysis: the so-called patent right is invalid. 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 confirmed by the Patent Reexamination Board and declared invalid. An invalid patent right is regarded as nonexistent from the beginning.

Legal basis: Article 45 of the Patent Law of People's Republic of China (PRC). Since the date when the patent administration department of the State Council announced the grant of the patent right, any unit or individual may request the patent administration department of the State Council to declare the patent right invalid if it considers that the grant of the patent right is not in conformity with the relevant provisions of this Law.
