1. Practical. That is to say, if the trademark has been used in American commerce, the date and evidence of the first use should be provided at the time of application.
2. Intentional use. That is, if you intend to use the trademark in the United States, you need to submit the use statement and evidence when you approve the registration (about 6 months under smooth circumstances).
3. Domestic trademark registration. That is, on the basis of domestic registration, it is necessary to provide a copy of the same domestic registration certificate as that applied by the United States and its English translation. Among them, "intentional use" and "domestic registration" can be converted to each other. When domestic applicants apply for the same trademark in China and the United States at the same time, they can choose to submit a trademark application to the United States on the grounds of "intentional use". If the trademark application in the United States is approved for registration, the American official may be required to change the original application basis to "domestic registration". If the application basis changes after receiving the approval notice, the application will be announced again (again entering the objection period).
In addition, the applicant can also apply for multiple categories of a trademark and specify different application bases, such as applying for four categories of trademarks, the first two categories are not used in the United States and the latter two categories have been registered in China. In this case, the first two categories can be required to be "intentional use" and the latter two categories can be required to be "registered in China".
