Using the Trademark Symbols: TM, SM and ®

Using the Trademark Symbols: TM, SM and ®
Any time you claim rights in a mark, you may use the "TM" (trademark) or "SM" (service mark)
designation to alert the public to your claim, regardless of whether you have filed an application
with the USPTO. However, you may use the federal registration symbol "®" only after the
USPTO actually registers a mark, and not while an application is pending. Also, you may use the
registration symbol with the mark only on or in connection with the goods and/or services listed
in the federal trademark registration.
