A plagiarism lawsuit against J.K. Rowling, author of the Harry Potter novels, will go to trial. The case will be heard following the ruling of the British judge overseeing the matter in favor of the plaintiff.

The lawsuit claims that the Rowling stole ideas from The Adventures of Willy the Wizard - No. 1 Livid Land by Adrian Jacob.

A one-day case hearing will be scheduled to hear the case, with Jacob's estate trustee Paul Allen required to pay money for security of the costs of the case. This development was welcomed by the lawyers of Paul Allen since it would result to J.K. Rowling and Bloomsbury to provide details how the similarities occurred. Rowling and Bloomsbury had previously refused to disclose notebooks and manuscripts.

The Harry Potter author and publisher Bloomsbury has appealed the court to dismiss the case asserting that the copyright infringement allegations by Mr. Jacob's estate has no chance of succeeding, but Justice Kitchin ruled to the contrary, even as he described Jacob's case as "improbable."

Rowling called the claims unfounded and absurd as she had only learned of Adrian Jacobs book back in 2004 whereas the idea for the "Harry Potter" series first came to her in 1990 during a train journey.

Her Harry Potter books sold more than 400 million copies so far. Forbes magazine estimates that Rowling has a wealth of $1 billion, making her one of United Kingdom's richest women.
