In this paper, priority is given to the invalid patent cases with patent infringement disputes, so as to determine the effectiveness of patent rights more accurately and timely and solve the outstanding problem of "long period" of patent protection in the current patent system operation. At the same time, when the patent involved in the patent invalidation case has great influence and significance, it is also necessary to better safeguard the national interests or social public interests through priority examination. Therefore, the new "Measures" stipulates that the priority review of patent invalidation cases applies to the following two situations:
1. In view of the patent infringement dispute involved in the patent invalidation case, the parties have requested the local intellectual property office to handle it, bring a lawsuit to the people's court or request arbitration mediation to organize arbitration mediation;
2. The patent involved in the patent invalidation case is of great significance to the national interest or public interest.
