SAN FRANCISCO Warner Bros. has won another significant victory in its epic legal struggle over the commercial rights to the Superman comic franchise.
The 9th U.S. Circuit Court of Appeals ruled Thursday that the heirs of Superman's co-creator, Jerome Siegel, must abide by a 2001 agreement they made with the studio. The ruling overturns a trial judge's decision in 2008 siding with the Siegel heirs in their attempts to expand their commercial control.
It's the second significant victory for the studio in its years-long battle for control of Superman. Three months ago, heirs for the other co-creator, Joseph Shuster, also lost their legal bid to regain a share of Superman's copyright.
Taken together, Warner Bros. now enjoys complete control of the Superman franchise. It plans tothis summer.
