What is the application of the day? What are the advantages of applying for utility model and invention patent on the same day?

The application on the same day refers to the same invention-creation, and only one patent right is granted. If there is duplication, it needs to be discarded. Special preference was given to the same invention on the same application date. In the request for a patent application, there is an option to apply on the same day, that is, to submit an application for a patent for invention and utility model on the same day for the same invention and creation. If this option is checked, the utility model will be patented first, and the invention can be authorized later. However, the applicant needs to give up the utility model patent, otherwise it will not be authorized. On the other hand, if the utility model is abandoned, the invention patent can be authorized. If the utility model is not authorized, it naturally has no influence on the invention right.
