The principle that applying for trademark registration shall not infringe the prior rights of others applies to the trademark registration systems of most countries and regions, and there are usually no geographical restrictions.

According to this principle, when applying for trademark registration, a trademark applicant should respect the trademark rights of others that have been registered or used in the same category or related categories. If a trademark application conflicts with someone else's prior trademark rights, the trademark registration agency or court has the right to reject the trademark registration application or declare the trademark registration invalid.

Before applying for trademark registration, it is an important step to conduct a trademark search and investigation to determine whether the applied trademark conflicts with other people’s prior trademark rights. Trademark searches should cover relevant countries or regions to ensure respect for prior trademark rights.

It should be noted that there may be some differences in trademark registration systems in different countries and regions. Therefore, in specific countries or regions, there may be some geographical restrictions or special regulations. It is recommended to consult a professional trademark agent or lawyer to understand the applicable laws and regulations before applying for trademark registration.
