How to Find Out If a Name Has Been Trademarked

Trademarks in the U.S. are either the state or federal level. If you would like to use a name, logo or phrase in which you feel is original, it is very important that you first verify that your idea has not already been trademark registered. If you knowingly or unknowingly use registered trademark, you could be held accountable for financial restitution for trademark infringement, and that could possibly become very expensive. Verifying if a name has already been trademarked could definitely save you money in the long run.

Tips & Warnings

  • The USPTO encourages anyone who is applying for a trademark or needs to do an in depth search for a trademark to hire an attorney that specializes in patents & trademarks. The attorney can also be very valuable if you decide to apply for a trademark.
