Amicus brief in visual meme case

While I'm at it, Chris Sprigman and I filed a brief on behalf of IP professors in a case against Fox News for republishing a 9/11 meme on a Fox Facebook page, with commentary on the order of "Never Forget"--the owner of the copyright in the photo of firefighters raising the American flag at Ground Zero, which was part of the meme, sued.  The brief argues that a meme of this sort, reflecting popular reaction to important events, is fair use.
