Ok, I think this is one of those situations that can best be described as shit hits fan.
In a nutshell: IBM has established in court that SCO has not met the requirements. Apparently only 17 files from SCO were named and even then only a few lines that were allegedly copied unlawfully from Unix. So definitely not the thousands of lines that SCO had announced so loudly. Furthermore, it looks as though SCO would be dropping the part about IBM's violation of trade secrets and the copyright business is probably also slowly falling apart.
And IBM apparently shows no signs of letting go. I think IBM's lawyers now want to bury SCO for good.
