If you trademark the name, it's only valid in your area, I think. Look at The Raconteurs in Australia (they go by The Saboteurs there due to another band being called The Raconteurs there), or The Barstool Prophets (Ottawa/Cornwall band that were originally The Wallflowers, until Jacob Dylan and his band made it big).

I don't think you can do anything if he's over there, and you're here...
