In re Electronic Database Litigation, 509 F.3d 116 (2d Cir. 2007) cert. granted March 2, 2009.
Does 17 U.S.C. §411(a) restrict the subject matter jurisdiction of the federal courts
over copyright infringement actions?
Section 411 is the "register before you sue" rule.
The U.S. Supreme Court has granted a petition for certiorari on this question. The Second Circuit, over the dissent of Judge Walker, vacated a class action settlement that authors and media companies had entered into after four years of negotiations.
The Second Circuit found that since the settlement covered unregistered copyrights (most of the authors writing for these publications), the federal court did not have jurisdiction to settle these claims.
I indicated my agreement with Judge Walker's dissent in my December 2, 2007 post here
