The establishment of trademark registration application date usually follows the following principles:

1. First come, first served principle:

-In the same trademark registration application category , the applicant who submits the trademark registration application first shall enjoy priority. Even if other applicants subsequently submit applications for the same or similar trademark, the applicant who applied first will still have priority.

2. Application submission principles:

-The trademark registration application date refers to the date when the trademark application materials are officially accepted by the Trademark Office or relevant agencies. The Trademark Office will usually give the applicant an application number and filing date after acceptance. The filing date is established based on the submission time of trademark application materials.

3. Complete application principle:

-A trademark registration application must contain complete application documents and necessary fees in order to be considered a valid application. Applications missing required documents or fees will not receive an established filing date.

Please note that the principles for establishing the filing date for trademark registration may differ from country to country or region to region. Specific trademark laws and regulations may have further regulations and requirements for the establishment of the filing date. During the trademark registration application process, it is recommended to consult the local trademark office or a professional trademark agency to understand the principles for establishing the accurate trademark registration application date.
