The Dragon Saga
Whale in a Teardrop
What's your evidence to the CM Punk thing? Usually if an entity owns a trademark, you can't use it elsewhere. Doesn't matter that Punk created it, it's registered under the WWE.
It was brought up on Jim Corentte's radio show back when the Punk Contract saga was going, and they gave a very detailed case of what happens when Superstars sign over their names.
Tommy Dreamer's name is trademarked by WWE in full. They own the name yet Dreamer is allowed to continue using it post-WWE as he's documented as the sole creator of the name and as an independant contractor has legal rights to use the name outside of the WWE.
Punk has evidence he was using the name pre-WWE; for several years obviously in IWA: MS and Ring of Honor, therefore he would at the very least be allowed to use the name there. But, they also discussed loopholes and one of them is his actual name.
CM Punk is trademarked, "C.M. Punk" is not trademarked. All Punk would even have to do is add in two full stops between the initial letters and he wouldn't be breaching any contract. But then again, as the most likely third option, they both own the name. Like "The Rock"; both WWE and Dwayne own it and both are free to use it as they please.
