Do you need your trademark symbol everytime you show your logo?
Answer:
No, it's not necessary to show the ® or the ™ symbols. However, doing so is a good idea because it does provide notice to others that you either have a Federally registered mark OR are claiming the rights to the mark. You can read more about those symbols here: http://www.uspto.gov/web/offices/tac/tmf. and here: http://www.uspto.gov/web/offices/tac/tmf.
Hope that helps!
