While that’s a good start, it’s not entirely complete. And the reason being, is that the United States follows the first to use rule under trademark law. What that means is that the first entity to make a valid use in commerce of the particular mark is the one that has rights. This is because under common law, as opposed to statutory law, the first to use is the one that gets the rights to use it moving forward, even if they do not pursue a trademark registration. This doesn’t mean that one should avoid getting a trademark registered with the USPTO. But what it does mean is that if you determine that someone has applied for or registered a trademark with the USPTO, and you believe you were the first to use it, you may have actions that you can take to further establish your rights. You might be able to file what’s known as a cancellation proceeding in front of the TTAB or you may jump right to litigation.
