The Madrid Agreement protects trademarks and service marks. The main content includes the application, validity, renewal, fees, etc. of trademark international registration. The Agreement stipulates that the international registration procedure for trademarks is that nationals of the member states of the Agreement, or nationals of non-member states who have domicile or real and effective business offices in a member country, first obtain the trademark in the country where they belong or the member country where they live or have no business office. Register, and then file an application for international registration of the trademark with the International Bureau of the World Intellectual Property Organization in Geneva through the country's trademark authority. If the application is approved, the International Bureau will announce it and notify the relevant member states where the applicant requested protection. These member states can declare within one year that the trademark will not be protected, but they need to explain the reasons; the applicant can file a complaint with the competent authority or court of the country. If a declaration of refusal of registration is not submitted to the International Bureau within one year, it can be deemed that the trademark registration has been agreed. Trademarks registered by the International Bureau are valid for 20 years and can be renewed an unlimited number of times. The Agreement facilitates nationals of its member countries to obtain trademark registrations in other member countries of the Agreement.
