First, I think that the Constitutional protection of "the Progress of Science and useful Arts, by securing for limited Times to Authors and Inventors the exclusive Right to their respective Writings and Discoveries" was intended to apply more to theories and inventions than to movies or, well, Mickey Mouse. That said, Article I, Section 8
has always been the standard for framing copyright and patent law. And I believe that such protections
should apply to literature, musical compositions, and other works of art in some form.
I wonder if some sort of compromise in this case could be reached in the grayer area of trademarks. If a sign, symbol, phrase, character, icon, or motto is created by a company and is closely identified with that company, it could be argued that that object should be protected for the life of
the company, rather than the individual who created it. This would obviously protect something like Mickey Mouse or Donald Duck or any of the
original Disney characters just as it would protect Mr. Clean, Aunt Jemima, or the Jolly Green Giant. I do
not believe that such protection should extend to characters derived from previously copyrighted material: no way should Disney be able to extend any kind of rights - even their original character designs - for, say, Rudyard Kipling's
The Jungle Book or Hans Christian Anderson's
The Little Mermaid.
As a slight tangent, I know that the James Joyce estate got an extension on the copyright of
Ulysses by virtue of releasing
Ulysses: the Corrected Edition - allegedly incorporating numerous corrections which had never made it into the original published editions (many of which, it transpires, were edited from the text and never
meant to have been incorporated into anything). I wonder if a similar argument could be applied to the evolution of Disney characters. "Ah, the copyright has expired on the
original Mickey Mouse - not the full-color version - or the Mickey whose solid black oval eyes evolved into white ovals with
pupils!" With
Ulysses as a precedent, a case
could perhaps be made...
Then again, I don't know enough about copyright law or trademarks or any of this to really put forward much of a learned opinion, so I'll shut up now.
(when does the copyright run out on these smilies??)
