Mmmm.it's an interesting notion, but if just Fender were to legally be able to say "we have sole rights and ownership of this "shape", how many other guitar manufacturers would go out of business. Here's a thought. Who came up with the truss rod? who came up with the "shape" for guitar frets? If they were able to TM it, what then? ......A song is "copyright" the owner. One point worth mentioning here as well is...., having "copyright" on a song doesn't mean I can't re-record it and sell it, AMCOS will issue you with, for a small fee, a "license" and you will pay "royalties" to the composer, which again is very little.
