Superman co-creator Jerry Siegel’s daughter Laura Siegel Larson wrote an open letter to fans about her long-running legal battle with Warner Bros. The long-running fight with Warner Bros. has taken an ugly turn in recent days as DC Comics has sued Siegel Larson and her lawyer Mark Toberoff, claiming unfair competition.Laura Siegel Larson and Joanne SIegel

The legal case took a turn in 2008 when Siegel Larson was able to exploit an aspect of copyright law with a California judge determining that her termination notice on copyright for the first editions of Action Comics telling Superman’s story were valid.

Toberoff and the family have promised to file an anti-SLAPP motion to dismiss the lawsuit.The case is headed for the U.S. 9th Circuit where lawyers for each side will make their case on the ownership of copyright, which could have a huge impact on Warner Bros. and DC Comics fortunes with the character for the foreseeable future. That could effectively take away control of their biggest cash cow.

Below is a copy of her letter to fans advocating her position.
