The TM and R symbols
Should I apply a TM or R symbol to my trademark?
Before we answer this question, let’s determine the difference between these two symbols. The TM symbol is used with a currently unregistered but pending trademark. In contrast, the R is used for a trademark that is already registered.
Whether or not you chose to apply a TM or an R symbol next to your mark is your decision; there is no legal requirement to use a symbol. That said, the greatest offense is a good defense. If you want to be proactive and ensure no one encroaches on your legal right to exclusively use your trademark, it could be a good idea to use the R symbol.
