Disney has acquired the rights to all the works Alan Dean Foster on behalf of the Star Wars franchise but refuses to pay him royalties earned. As Foster says, "“When you purchased Lucasfilm you acquired the rights to some books I wrote,” explained Foster in a statement addressed to Disney. “STAR WARS, the novelization of the very first film. SPLINTER OF THE MIND’S EYE, the first sequel novel. You owe me royalties on these books. You stopped paying them.”
Foster’s Star Wars novels are not the only books for which Disney is withholding royalties, as the author notes that “when you purchased 20th Century Fox, you eventually acquired the rights to other books I had written,” which included “the novelizations of ALIEN, ALIENS, and ALIEN 3”, a trio of novels for which Foster claims Disney “never paid royalties on any of these, or even issued royalty statements for them.”
Can this in any possible way be legal when it comes buying the rights to intellectual property?
