Are you sure about that? because trade mark of ROGERS is like "®" as in RO3000®. i thought it might have to dowith test method.
 

  • ™ (the "trademark symbol", which is the letters "TM", for an unregistered trademark, a mark used to promote or brand goods)
  • ℠ (which is the letters "SM" in superscript, for an unregistered service mark, a mark used to promote or brand services)
  • ® (the letter "R" surrounded by a circle, for a registered trademark)

A ™ Is worth only as much as you can afford in legal costs to prove it belongs to you 1st.

So anyone can use ™, and it is worthless until your business can afford the legal costs to defend it, if necessary.
