The USA used to, and I think still does, have strict marking requirements for patents and trade marks, so if you do not positively say that something is a trade mark by using "TM" ( for an unregistered trade mark) , "RTM" ( for a registered trade mark), or use the R in a circle symbol, then you risk losing any protection you might have had.
