The judge ruled that the 2006 case did not adequately interpret what a 1948 court said, and he needs to see more supporting documentation from both sides as to whether Superboy as published in "More Fun Comics" #101 was derivative of Superman. What it's going to boil down to is this: was there anything copyrightable in Siegel's original plans for Superboy, or was it basically derivative of Superman? They've got 30 days from July 27 to present their case, making the due date August 26.
