27. Will there be any inconsistency between the priority date and the application date?

1. Priority is a subsidiary right of patent application right. Without the right of patent application, there is no priority.

2. Only after the patent applicant files a patent application can the patent application right have priority.

3. Priority has strict time limit, that is, priority is only valid within the priority period stipulated by law, and it is invalid after expiration.

4. Where the two applications filed by the patent applicant are in the same country, the priority enjoyed by the patent applicant is domestic priority; If it is in different countries, it is foreign priority.

5. Priority cannot be automatically generated, that is, if the patent applicant requests priority when filing the latter application, he must file an application for priority at the same time as filing the latter application, and submit the corresponding valid certification documents as required, and the priority can only be generated after passing the examination.

6. The latter application claiming priority must have the same theme as the earlier basic application, but the theme of the latter application can be the improvement of the earlier basic application.
