Question: Is my United States trademark registration protected internationally?
Answer: No. A trademark registration in the US only provides you rights in the United States and its territories. If you want trademark protection in any other country, you must file your trademarks on a country-by-country basis.
The one exception to this rule is when registering trademarks in the European Union. The EU provides the opportunity to file just one application for coverage in all EU countries.
Otherwise, it’s important to understand that your U.S. registration is only valid and enforceable in the United States. If you want trademark rights in any other country, there is no single international registration you can obtain. Here is a separate video on how international trademark registration works.
