What is the difference between invalidation of patent right and revocation of invalidation of patent right? Under what circumstances can I request cancellation?

1. What is the invalidity of patent right In order to correct the wrong authorization that may be made by the patent office, the patent law not only stipulates the procedure for revoking the patent right, but also stipulates the procedure for declaring it invalid. After the expiration of six months from the date when the Patent Office announced the authorization, any unit or individual may request the Patent Reexamination Board to declare the patent right invalid or partially invalid if it considers that the grant of the patent right is not in conformity with the relevant provisions of the Patent Law. Setting an invalid program and canceling the program have the same purpose, but they are different. 1. The procedure for invalidation shall be filed six months after the authorization announcement of the Patent Office, and the request for invalidation may also be filed after the termination of the patent right. 2. The reasons for the invalidation of the request include not only all the reasons for the request for revocation, but also insufficient publicity; The modification is beyond the scope of original disclosure; Repeated authorization for the same invention-creation; The person who was granted the patent right for invention-creation was not the first person to apply for the patent. Two. According to the provisions of Article 49 of the Patent Law, the Patent Reexamination Board has decided to examine the request for invalidation in the following three situations: 1, the reason for the request for invalidation is established, and the patent right is declared invalid according to law. According to Article 59 of the Patent Law: "The patent right that has been declared invalid shall be regarded as nonexistent from the beginning". On the basis of invalid patent right and urban patent infringement disputes, those who have not filed a lawsuit cannot file a lawsuit on the grounds of patent infringement, and those who have filed a lawsuit but have not yet made a judgment or have made a judgment have not yet been executed, their litigation request shall be rejected or execution shall be terminated. 2. If the reasons for the request for invalidation are established, the patent right shall remain valid after the part is declared invalid according to law or the claim is amended. When the patent right is declared partially invalid, the situation is more complicated, and specific problems should be analyzed. If part of the patented technology involved in the implementation is declared invalid, the dispute shall be handled in the same way as the result of the aforementioned 1 case. To maintain the validity of part of the patented technical content involved in the implementation, it is necessary to make a conclusion after comparing the scope defined by the claim with the technical content involved in the implementation according to the provisions of Article 59 of the Patent Law. 3. If the reasons for the request for invalidation are not established, the request for invalidation shall be rejected and the original patent right shall remain valid. In this case, the patent right is maintained and continues to be effective, indicating that the existence of the patent right has not caused any infringement on the public interest, so the legitimate rights and interests of the patentee should be safeguarded according to law. However, the continued validity of the patent right does not mean that the implementation of the act must constitute patent infringement. It is also necessary to analyze and judge whether the implementation behavior constitutes infringement according to the provisions of the patent law and professional knowledge.
