What do the symbols TM, ® and © mean?

“TM” is common law trademark notice that can be placed adjacent registered and unregistered marks of the owner. It is best to make sure a new trademark is clear of conflict with other trademarks before adapting the trademark and using trademark notice. ® is used adjacent a trademark after it has been registered only. © is a portion of copyright notice that can be freely used adjacent any works for which the author or owner claims copyright rights. Full copyright notice is “©, year, owner” (i.e. © 2009 Heisler & Associates).
