It's been ruled. SCO does NOT own the the UnixWare and UNIX copyrights, but rather, Novell. From Groklaw:
That's Aaaaall, Folks! The court also ruled that "SCO is obligated to recognize Novell's waiver of SCO's claims against IBM and Sequent". That's the ball game. There are a couple of loose ends, but the big picture is, SCO lost. Oh, and it owes Novell a lot of money from the Microsoft and Sun licenses
But we must say thank you to Novell and especially to its legal team for the incredible work they have done. I know it's not technically over and there will be more to slog through, but they won what matters most, and it's been a plum pleasin' pleasure watching you work. The entire FOSS community thanks you for your skill and all the hard work and thanks go to Novell for being willing to see this through.
I'm eating chocolates!
Sorry SCO. Have a nice trip. Don't let the door hit you on the way out.
