WWE Trademarking Wrestlers Move Names?


                        Has the WWE ever tried to trademark wrestlers move names?  For example, I've heard announcers from other wrestling companies refer to a "Tombstone- Piledriver" or a "Pedigree"  Kind of weird that they haven't seeing as they do with names and characters.  Any idea? 

They absolutely trademark the s--- out of move names.  And if they catch other companies doing that, you can bet they'll get a letter about it.
