SCO, a now bankrupt Unix company sued IBM several years ago for billions claiming that proprietary Unix code was embedded in IBM’s Linux. As it turns out SCO was full of crap.
The final judgment has occurred. Bye-bye SCO. 
Well, they were suing everybody who used Linux, claiming that they “owned” Unix, and that some of the Unix source code found its way into Linux (via IBM and others).
Trouble is, Novell owns Unix, not SCO.
Yeah. You would think that Darl would have checked into this a bit more prior to suing everyone in the Solar System. Good riddance.
