Lex Luger, Rick Rude, Randy Savage...

These are guys (off the top of my head) that when they jumped ship to WCW, they kept their WWF name.

How did they manage this? Would'nt these names have been trademarked by WWF, like Diesel/Razor Raymond?

[#BROKEN Hasney]

Luger and Rick Rude were in WCW before WWF and probably already owned the trademark.

I know Savage owned the trademark to his own name for sure.

Bam Bam Bigelow, British Bulldog, Jake the Snake, and junkyard dog all got to keep their name

Also, who the hell is Razor Raymond? Never heard of that rassler.

Diesel and Razor were gimmick names specifically created by the WWF, the others weren't.

Randy used the name Randy Savage when he started in the mid 70's so he already owned the name
