With the closing of Bill Patry’s Copyright Blog, there’s a distinct absence of copyright wonkery on the web. So I will occasionally do my best to chip in. Today’s case raises the following possibility: Suppose you run a business heavily dependent on a certain software program. And suppose the owner of that program keeps writing you cease and desist letters, saying that your copy is infringing and that each passing day accumulates more actual damages, as well as your profits attributable to the infringement. You want to clear this cloud from your business, and heaven forfend, if you are found to be infringing, put a cap on the damages. But let’s suppose the owner hasn’t gotten around to actually registering the copyright yet. Can you sue for a declaratory judgement action?

In Weitzman v. Microcomputer Resources, the Eleventh Circuit said no. That intolerable situation can persist until the owner finally decides to sue you instead.

Judge Patterson in the Southern District of New York issued his opinion today in the Harry Potter Lexicon case, which involved an attempt by the defendants to convert their very popular website into print form and sell it. J.K. Rowling and the studio behind the Harry Potter films sued, and the court held that the Lexicon was not protected by fair use.

I’ve only had time to skim the decision, but my quick take is that a district court in the same circuit that decided the Seinfeld Aptitude Test case (Castle Rock Entertainment v. Carol Publishing Group, 150 F.3d 132 (2d Cir. 1998)) would have had a hard time finding fair use here. If multiple choice questions based on “Seinfeld” infringe on the show, then encyclopedia entries based on Harry Potter probably do, too. That’s not an endorsement, just a syllogism.
