There is some new news about the JK Rowling vs. RDR books now online.  You can see another article here as well.

U.S. District Judge Robert Patterson Jr. said the copyright infringement case was a legal close call, involving unresolved areas of American law, and was almost certain to end in years of appeals.

“I don’t want to be influenced by either party’s attitude toward settlement,” said Judge Robert Patterson today, at the start of the third day of trial. “I think this case, with imagination, could be settled . . . . But don’t throw anything out because of my desire to move ahead.”

UPDATE: JKR released another statement about this issue.  You can also read more HERE!

The book at the heart of this case has overstepped a boundary so unreasonably that I have been forced, regretfully, to take legal action. Authors have a right to protect their works from misuse. Do I have fewer rights because many people read my books? If this book is published, it will open the floodgates for anyone to lift an author’s work and present it as their own. But if it is not published, that will be a boon not only to all who create original works, but to all who enjoy those works.
