Thanks to the Madrid Agreement and the Madrid Protocol, and the corresponding Regulations for Common Execution of these two treaties (the Regulations), within one application, the trademark can be protected in nearly 100 countries including members of the EU, a majority of Eastern European countries, the USA, Russia, China, Japan, Switzerland, Australia and many more.
These agreements were signed to simplify the administrative effort for the extension of the trademark protection in other countries. This system is administered by the (WIPO) in Geneva.
As Hong Kong, Macao and Taiwan have a different legal system, they are not included under the Chinese trademark. For these regions, a separate application to obtain the trademark protection is needed.
