I believe a trademark [TM] can be used for anything you give away or sell
or for a name used in trade.  A registered TM is one that has been
registered with the US Patent and Trademark Office.  The registered [TM]
would be easier to enforce, although I do not know if the penalties are
any different.

I doubt there would be a potential problem if you misidentify a
registered TM in a publication.  But then I'm no lawyer.

I remember reading an article about this in MacUser or MacWorld within
the last three years.

Good luck,
