Apart from trademark protection, what kind of intellectual property protection may logos have under US law?
Could a logo be considered a graphical "work", therefore copyrightable? If it could, how? By measuring the level of creativity used for creating it? For example, how would creativity be measured for a logo created using a slightly modified typeface, as opposed to a logo drawn in an entirely original way? Would the former be copyrightable given that copyright doesn't protect typefaces?
Could a logo be considered an industrial design? If it could, would the concept of "author", as in the specially ordered or commissioned designer, even be relevant? Who would own the industrial design rights to the logo then?
