The utility model patent and invention patent submitted on the same day, only the utility model was submitted at the time of application, can I submit the invention patent now?

No, the utility model of the earlier application will conflict with the invention of the earlier application.

The invention patent can't stand the right.

Article 9 of the patent law

Where the same applicant applies for a patent for utility model and an invention patent for the same invention-creation on the same day, and the earlier obtained patent for utility model has not been terminated, and the applicant abandons the patent for utility model, the invention patent may be granted.

The application must be filed on the same day, otherwise the invention cannot be authorized.
