Legal basis: Article 45 of the Patent Law of People's Republic of China (PRC). Since the date when the patent administrative department of the State Council announced the grant of the patent right, any unit or individual may request the Patent Reexamination Board to declare the patent right invalid if it thinks that the grant of the patent does not conform to the relevant provisions of the Patent Law. That is, from the date of patent authorization, any person or unit may request invalidation of the patent.
1. Where a patent right is requested to be declared invalid or partially invalid, a fee shall be paid in accordance with the regulations, and a request for invalidation shall be submitted in duplicate, indicating the name and patent number of the patent requested to be declared invalid, the facts and reasons on which it is based and the necessary evidence.
2. The Patent Reexamination Board shall send a copy of the request for invalidation of the patent right and relevant documents to the patentee, requesting the patentee to state his opinions within a specified time limit. The patentee may modify the patent document, but shall not expand the scope of the original patent protection. If the Patent Reexamination Board fails to reply, it will not affect the trial.
3. The Patent Reexamination Board shall examine the request for invalidation of the patent right, make a decision, and notify the requester and the patentee. The decision to declare the patent right invalid shall be registered and announced by the China Patent Office. An invalid patent right shall be regarded as nonexistent from the beginning.
