Finally, the root of what we've been waiting for. Everyone with a brain knew that this was a copyright case, yet until now it wasn't even in the lawsuit.
I would presume that the judge is going to want the copyright claims simplified in black and white:
1. What relevant copyrights have been filed and are on-hand at the Library of Congress?
2. What is the chain of ownership for those copyrights?
3. What physical lines of code violate said copyrights?
Let's see the code! Let's see the filed copyrights! Let's see the chain of ownership!
...And then let's get this case settled.
