Who's got an Invisibility Cloak handy? Following three days of emotional testimony, a New York judge presiding over J.K. Rowling's copyright case has urged the author to stop litigating and start settling.

Judge Robert Patterson Jr. told the Harry Potter author and coplaintiff Warner Brothers that copyright infringement has a lot of gray areas in American law, and that the litigation could go on for years of appeals, according to the Reporter. "I think this case, with imagination, could be settled," he said.

As previously reported, Rowling filed the suit against a publisher that plans to print the Harry Potter Lexicon, an encyclopedia compiled by Steven Vander Ark, who has a website with similar content. Vander Ark's publisher, RDR, asserts that the encyclopedia would be used for scholarly use, and would not impact Rowling's sales.

If some of the publishing experts who testified at the case are any indication, the book may find plenty of readers, but probably wouldn't be making the New York Times best-seller list. One such maven called the Lexicon "poor" in quality. What's your opinion? Would settling work magic on this case, or should Rowling stick to her spells and keep litigating? - Anna Dimond
