Toberoff said earlier that he would appeal another significant Warner Bros. victory won in October involving the family of Superman's other creator, Joseph Shuster, and their bid for half the commercial rights. Toberoff also represents the Shuster heirs, who lost their bid to retain a 50 percent share of Superman.
A federal judge in Los Angeles had ruled that Shuster's sister and brother relinquished any chance to reclaim Superman copyrights in exchange for annual pension payments from DC Comics. U.S. District Judge Otis Wright noted in that case that the families of both creators have been paid in excess of $4 million since 1978, plus undefined bonuses and medical benefits.
In April, the $412 check that DC Comics wrote in 1938 to acquire Superman and other creative works by Shuster and Siegel sold for $160,000 in an online auction.
