Legal analysis: Formal review is to check whether the trademark registration application submitted by the applicant complies with the requirements of the Trademark Law for trademark registration applications (such as whether the filling in the trademark registration application is true, correct and accurate , clarity, completeness, whether fees have been paid, etc.), and make a review on whether it is acceptable.

Legal basis: "Regulations on the Implementation of the Trademark Law of the People's Republic of China" The application date for trademark registration shall be based on the date of application documents received by the Trademark Office. If it is deemed through review that the application procedures are complete and the application documents are filled in in accordance with regulations, an application number will be assigned and a "Notice of Acceptance" will be issued. If the application procedures are not complete or the application documents are not filled in as required, the application will be returned and the application date will not be retained. The application procedures are basically complete or the application documents basically meet the regulations, but if they need to be supplemented or corrected, the applicant will be notified to make supplements and corrections. If the applicant makes corrections and returns them to the Trademark Office within the prescribed time limit, the application date will be retained
