NewYorkCountryLawyer writes "J. K. Rowling didn't make enough money on Harry Potter, so she had to make sure that the 'Harry Potter Lexicon' was shut down. After a trial in Manhattan in Warner Bros. v. RDR Books, she won, getting the judge to agree with her (and her friends at Warner Bros. Entertainment) that the 'Lexicon' did not qualify for fair use protection. In a 68-page decision (PDF) the judge concluded that the Lexicon did a little too much 'verbatim copying,' competed with Ms. Rowling's planned encyclopedia, and might compete with her exploitation of songs and poems from the Harry Potter books, although she never made any such claim in presenting her evidence. The judge awarded her $6,750 and granted her an injunction that would prevent the 'Lexicon' from seeing the light of day." Groklaw has an exhaustive discussion of the judgement.
