Is a federal registration valid outside the United States?
No. However, if you are a qualified owner of a trademark application pending before the PTO, or of a registration issued by the PTO, you may seek registration in any of the countries that have joined the Madrid Protocol by filing a single application. Also, certain countries recognize a United States registration as a basis for filing an application to register a mark in those countries under international treaties (the Paris Convention). You can also file individual applications in many foreign countries. As a result of goods and services sold over the Internet with the trademark, careful consideration should be given to selecting and protecting the appropriate marks in various countries.
