Do federal regulations govern the use of the designations “TM” or “SM” or the ® symbol?
If you claim rights to use a mark, you may use the “TM” (trademark) or “SM” (service mark) designation to alert the public to your claim of ownership of the mark, regardless of whether you have filed an application with the United States Patent and Trademark Office (USPTO). However, you may only use the federal registration symbol “®” after the USPTO actually registers a mark, and not while an application is pending.
