Trademark inquiry refers to the inquiry whether the trademark applied by the applicant for trademark registration or his agent is the same as or similar to the trademark that enjoyed the prior right before applying for registration. Inquiry is not a necessary procedure for trademark registration. The scope of inquiry is limited to the registered trademarks and trademarks in application that have entered the database of the Trademark Office since the date of inquiry, and does not include the prior rights information in the review state. This result has no legal effect, and is for reference only, and is not used as the basis for the Trademark Office to approve or reject the application. Trademark inquiry is a professional job. You can entrust a trademark agent to inquire on your behalf, and you will get more accurate advice. Trademark inquiry can also entrust the organization of the Trademark Office to access the Trademark Affairs Center, and the inquiry result is relatively accurate. Trademark analysis refers to whether the trademark application filed by the trademark registration applicant or his agent violates the provisions of the Trademark Law prohibiting the registration or use of the trademark. This is also a work that must be done before trademark application to improve the success rate of trademark application.
