Copyright dispute

On September 16, 2009, Kirby's four children served notices of termination to The Walt Disney Studios, 20th Century Fox, Universal Pictures, Paramount Pictures, and Sony Pictures to attempt to gain control of various Silver Age Marvel characters. Marvel sought to invalidate those claims. In mid-March 2010 Kirby's children "sued Marvel to terminate copyrights and gain profits from comic creations." In July 2011, the United States District Court for the Southern District of New York issued a summary judgment in favor of Marvel, which was affirmed in August 2013 by the United States Court of Appeals for the Second Circuit. The Kirby children filed a petition on March 21, 2014, for a review of the case by the Supreme Court of the United States, but a settlement was reached on September 26, 2014, and the family requested that the petition be dismissed. While the settlement has left uncertain the legal right to works governed by the Copyright Act of 1909 created before the Copyright Act of 1976 came into force, the Kirby children's attorney, Marc Toberoff, said (in 2014) that the issue of creators' rights to reclaim the work done as independent contractors remains, and other potential claims have yet to become ripe.
