Free Trademark Search
Trademark searches are essential for all musicians. In order to be certain that the name you choose for your band or yourself is not registered to someone else, it is necessary to do a trademark search. Otherwise, you leave yourself open to being sued by the legal owner of the name, something that can be both expensive and time-consuming.
Most companies/ lawyers that perform trademark searches for you charge a great deal of money for their service, however, you can do it yourself quite easily.The U.S. government trademark and patent office has an electronic search system which anyone can access. Once you have found that your name does not belong to someone else - you can easily fill out the free forms to start the process of making it your own.
WARNING: AFTER SEARCHING THE USPTO DATABASE, EVEN IF YOU THINK THE RESULTS ARE "O.K." DO NOT ASSUME THAT YOUR MARK CAN BE REGISTERED AT THE USPTO. AFTER YOU FILE AN APPLICATION, THE USPTO MUST DO ITS OWN SEARCH AND OTHER REVIEW, AND MIGHT REFUSE TO REGISTER YOUR MARK.
On the U.S. Patent and trademark website there is a wealth of information for the taking. Be smart - be sure.
