Can a person's name be copyrighted?

I’m not so sure about that. Admittedly he doesn’t call himself “Elvis Presley”, but then again, “Elvis” by itself is also a trademark of Elvis Presley Enterprises. And this Google Books page claims that they sued a nightclub for using “Elvis” as part of its name. (The reference is at the bottom of the displayed page).

Again:

(1) “Armed Forces / Elvis Costello and the Attractions” on the cover of an album is not a trademark use. It is merely use of a name (albeit an assumed one) as a name. The nightclub situation is, however, a trademark use.

(2) I would be very surprised if any court concluded that a use like “Armed Forces / Elvis Costello and the Attractions” had created a likelihood of confusion with “Elvis” or “Elvis Presley.” It’s just too obvious that “Elvis Costello” is not the same person as “Elvis (Presley).” In the likelihood of confusion test, a court would take into account the fact are other people named “Elvis” and that everyone knows that there can be other people named “Elvis,” especially when used with a family name.
