Use of Trademark Designations in the United States Patent & Trademark Office
There are no federal regulations governing the use of the designations “TM” or “SM” (Trademark or Service Mark) by the United States Patent & Trademark Office. Local, state, or foreign laws may govern use of these designations, and a trademark attorney should be consulted.
Once the mark is actually registered in the United States Patent & Trademark Office, the federal registration symbol may be utilized. It is important to note that the registration symbol may not be utilized before the mark has actually become registered, even though there may be a pending application. Only goods or services that are the subject of the federal trademark registration should use the federal registration symbol.
You would be wise to consult with a Florida trademark lawyer first, before undertaking any trademark matters.
