I took your workshop. Can I use Repetitive Use Injury Therapy (RUIT)® and the Muscle Release Technique℠ to advertise on my business cards?

Repetitive Use Injury Therapy (RUIT)® is the name of our business.  You can not use this name in your advertisements.  The name of the technique that Michael teaches is the Muscle Release Technique℠.  You can certainly advertise that you trained under Michael Young and that you took his workshop to learn the Muscle Release Technique℠.  Since the Muscle Release Technique℠ is a trademarked technique, you simply need to put the symbol for the trademark (which is ℠ since this is a service) each time you use the words Muscle Release Technique℠ in print.
