Did the original keychain versions of Bumblebee, Cliffjumper, Brawn and Windcharger have trademark claims after their names on the packaging? As in Bumblebee™ or Bumblebee®. Same for the term "Autobot". If yes, which ones were ™ and which ones were ®? This question is mainly aimed at the original releases of the keychains, but anyone who has the "Heroes of Cybertron" re-releases by Basic Fun could also help.
