How to understand the "same theme" in the definition of patent application priority and how to define it in judicial interpretation?

The same theme generally means that the objects to be protected are the same, and the claim to be protected in the latter application, if any, can claim priority.

The simple explanation of the same theme is: whether in the same field, whether the technical solutions are basically the same, whether the problems solved are the same, and whether the effects achieved are basically the same.

Reference: It is clearly stipulated in Section 4.6.2, Chapter 8, Part II of the Examination Guide that the above item (1) should be verified, that is, the application documents of the earlier application should be taken as a whole to judge whether the technical scheme required by the claims of the latter application is based on it, that is, it should be supported. If the technical scheme required by the claim in the latter application is obtained or summarized by the technical personnel in the technical field in the fully disclosed technical content of the application documents in the earlier application, the claim can enjoy the priority of the earlier application, otherwise it will be rejected.

Hope to adopt!
