Top of page Q: Are there federal regulations governing the use of the designations “TM” or “SM” with trademarks?
No. Use of the symbols “TM” or “SM” (for trademark and service mark, respectively) may, however, be governed by local, state, or foreign laws and the laws of the pertinent jurisdiction must be consulted. These designations usually indicate that a party claims rights in the mark and are often used before a federal registration is issued.
