Termination of patent right Why will the patent right be terminated? After the termination of the patent right, the invention will become the wealth of society, and any unit or individual can use it for free.

The Patent Office will issue a notice of payment, informing the applicant that after paying the annual fee and overdue fine, if the applicant still fails to pay or fails to pay the annual fee and overdue fine in full, the patent right will be terminated from the date of expiration of the previous year. 2. The patentee waives the patent right in writing. Since the date of authorization, if the grant of the patent right does not conform to the relevant provisions of the Patent Law, any unit or individual may request that the patent right be declared invalid.

If a party refuses to accept the decision on the request for invalidation of a patent, he may bring a suit in a people's court within three months from the date of receiving the notice. The patent office shall register and announce the decision after it becomes legally effective. An invalid patent right shall be regarded as nonexistent from the beginning. 3.
