J.K. Rowling may have dreamed up boy-wizard Harry Potter, but the author didn't need any magic to get her plagiarism case thrown out.

U.S. judge Shira Scheindlin has dismissed claims that the author copied another writer in 'Harry Potter and the Goblet of Fire,' the fourth book in her popular series.

reports that the estate of deceased author Adrian Jacobs previously asserted that Rowling had borrowed from Jacobs' 1987 book 'Willy the Wizard - No 1 Livid Land.'
