What do “TM,” “SM” & “” Mean?
The symbols , TM and SM provide notice to the world that you are claiming trademark rights in any mark using these symbols. You may use the TM on marks identifying goods, and the SM on marks identifying services. You need not have a federal or state registration to use the TM or SM symbols. However, the symbol, which provides “statutory notice” can only be used if your mark is federally registered.
