Per Michael Grabois, the prior ruling giving the Siegel family rights to the Superboy character will be reconsidered in the courts. Each side has 30 days to submit revised information.
The bottom line: DC successfully appealed the 2006 ruling, which said that the Siegels had successfully regained the rights to Superboy. 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.
