Following an appellate mandate, a federal judge in California granted summary judgment to Warner Bros. in late March, all but ending almost a decade of copyright litigation between the entertainment conglomerate and Laura Siegel Larson, heir of Superman co-creator Jerry Siegel. See Larson v. Warner Bros. Entm't, Inc., 2013 WL 1164434 at * 9 (C.D. Cal. March 20, 2013). In a counterclaim, Warner Bros. sought (and was granted) a declaratory judgment that an October 2001 letter from Larson's then-attorney to Warner Bros.'s then-general counsel constituted a binding contract regarding the rights to the Man of Steel, even though subsequent negotiations to formalize the agreement fell apart. In January, the Ninth Circuit considered the letter kryptonite to Larson's claims under California law because it "constituted an acceptance of terms negotiated between the parties," specifically and accurately reflecting "the material terms [counsel for both parties] had orally agreed to" during a conversation three days earlier, in which they "had resolved the last outstanding point in the deal" following "years of negotiations." See Larson v. Warner Bros. Entm't, Inc., --- F.App'x. ---, 2013 WL 1113259 at *1 (9th Cir. 2013).
