The Validity of Federal Registration with the United States Patent & Trademark Office Outside of the United States
Even though federal registration is not valid outside of this country, qualified owners of trademark applications either pending before the United States Trademark & Patent Office or of an issued registration, may seek registration in any country recognizing the Madrid Protocol by filing a single application.
This single application is referred to as an “international application” with the International Bureau of the World Property Intellectual Organization, through the United States Patent & Trademark Office. It should also be noted that select countries recognize a United States registration as a basis for filing an application to register a mark in those countries under international treatise. It is important, however, to consult the laws of each country regarding registration.
You would be wise to consult with a Florida trademark attorney first, before undertaking any trademark matters.
