What do the symbols TM, \, and sm after the mark mean?
Anyone who claims rights in a mark may use the TM (trademark) or SM (service mark) designation with the mark to alert the public to the claim. It is not necessary to have a registration, or even a pending application, to use these designations. The claim may or may not be valid. The registration symbol, , may only be used when the mark is registered in the PTO. It is improper to use this symbol at any point before the mark is registered. A state registration does not give one the right to use the symbol.
