As we suspected, the "Dumb Starbucks" store in Los Angeles claiming a right to copy Starbucks's logo and store design by relying on fair use turned out to be a prank after all (bolstered, as I did not realize yesterday by the fact that despite what the store said about selling coffee, they were actually just giving it away). It turns out that Nathan Fielder of Comedy Central was behind the whole thing, for use on his show "Nathan for You." Less funny for him was that yesterday the Los Angeles Board of Health closed the store for distributing food products without the proper licence.
So ends, it would seem, this little episode, but one that provided a useful starting point for a discussion about trademark, art, and fair use.
