Looks like Warner Bros is finally free of the last copyright Kryptonite plaguing its ownership of Superman. The 9th Circuit Court of Appeals today handed the studio another legal win in its battle with the estates of the Man of Steel’s co-creators Jerry Siegel and Joe Shuster – and the court did it with some degree of humor. “In this appeal, we address another chapter in the long-running saga regarding the ownership of copyrights in Superman — a story almost as old as the Man of Steel himself,” said the court’s memorandum today read it here reaffirming an earlier ruling for WB by district Judge Otis Wright III.“We are obviously very pleased with the court’s decision,” said a WB spokesperson in an understatement today. The Appeals Court decision was 2-1, with Judges Stephen Reinhardt and John Sedwick in the majority and Judge Sidney Runyan Thomas dissenting. The 9th Circuit also makes a point of admonishing the estates and their lawyer Marc Toberoff for playing hide and seek with certain facts.
