At present, the US Patent and Trademark Office adopts the Nice classification, but its goods or services often require more detailed requirements than the goods or services in the Nice classification, accepting multiple types of applications in one form. The elements that can be registered as trademarks in the United States include: text, letters, numbers, graphics, color combinations, three-dimensional shapes, sound, etc.

Natural or legal persons who do not have a domicile, main place of business, or a genuine and valid business enterprise in the United States must entrust a specialized agent in that country to handle the matter. The basic materials required for trademark application are:
1. Trademark design;
2. Category and specific product items;
3. Name and address of the applicant;

Application basis (intended use, actual use, or registration in the country of origin). If intended for use, evidence of use in the United States must be submitted before trademark registration; If it is for actual use, at the same time as submitting the trademark application, it is necessary to indicate the time of first use in the United States and submit evidence of the use of the trademark in the United States; If submitting a US application based on registration in the country of origin, a scanned copy of the trademark registration certificate from the country of origin and an English translation must be submitted;

If priority is declared, the application number and application date of the priority basis need to be submitted.

The main process of applying for registration of a US trademark is: application examination (absolute and relative reasons) announcement approval and issuance. The examiner will conduct formal and substantive examinations on the application. Formal review mainly examines whether the application requirements and classification information comply with regulations; The substantive examination includes the examination of the distinctiveness of the trademark, whether it violates the prohibition and prohibition clauses, and whether it conflicts with the prior trademark. If the review fails, a rejection notice will be issued and the applicant will be required to respond within the time limit specified in the rejection notice. Those who pass the substantive examination will be arranged for announcement. The opposition period is 30 days from the date of announcement. Interested parties may raise objections to the trademark application to the Patent and Trademark Office. The main reasons for raising objections are:

Conflict with prior trademarks, such as owning a prior registered trademark; Having a prior unregistered trademark but having prior use in the United States, etc;
1. The trademark lacks distinctiveness;
2. The trademark has adverse effects;
3. Malicious registration;
4. Conflict with other prior rights, such as trade name rights, design rights, copyrights, personal names, etc.

If there are no objections or objections are not valid during the announcement period, registration can be approved and a registration certificate can be issued. In a smooth situation, trademark registration in the United States takes about 12 months; If there is a rejection or objection, the time will be extended, which may take 2-3 years.
