After a trademark is registered, it will not automatically be used in all countries. The validity of a trademark registration is usually limited to the country or region where the application is made. However, trademark protection can be obtained in other countries or regions through the following methods:

1. International trademark registration: Through international trademark registration systems, such as the Madrid Agreement and the Implementing Regulations of the Madrid Agreement, trademarks are held A person can extend a trademark to multiple countries or regions participating in the agreement through one application. This simplifies the process of cross-border trademark registration.

2. Separate country/region registration: Trademark holders can apply for trademark registration separately in each target country or region. This requires compliance with national or regional trademark laws and procedures, including filing an application, paying fees, and meeting other requirements.

3. Regional trademark registration: In some regions, such as the EU's trademark registration system, trademark holders can obtain trademark protection in multiple member states by registering trademarks in this region.

It should be noted that the application and protection procedures for trademark registration may differ in various countries or regions, including fees, time and document requirements. Trademark holders should take appropriate measures to expand the scope of trademark protection based on the needs of the target market and legal requirements.
