The Sandman writer, who was awarded a 50/50 split in the rights to Angela and Medieval Spawn, said that Judge Richard A. Posner's decision sets a precedent for dual copyright in the comics industry.
"The main thing is, I feel like an awful lot of good things have come out of it," he told the Washington Post. "I think the various decisions, particularly the [Judge] Posner decision, were huge in terms of what the nature of dual copyright in comics is.
"What is copyrightable in comics is now something that there is a definite legal precedent for. There were a lot of things that were… misty in copyright [law] that are now much clearer. And it's of benefit to the creator."
McFarlane and Gaiman now share the ownership of Spawn #9 and #26, as well as the first three issues of its Angela spinoff. A 2010 ruling saw Gaiman entitled to a share of the profits from Dark Ages Spawn, Domina and Tiffany, which were ruled as derivatives of characters he created.
Gaiman said that the profits he won will be donated to charity.
