The court has already decided many of the claims against SCO including copyrights and ownership. The claim in this order was about tortious interference: Did IBM, by hardening Linux and porting code over to Linux, maliciously interfere with SCO's customers and business relationships?
Like many of SCO claims, the tortious interference were ambiguous and ever changing and lacked any detail. The number of parties that SCO alleged that IBM had caused interference changed by the month despite IBM asking repeatedly (and the court ordering SCO to respond repeatedly) to name the parties and the detail the interference. It was as low as 3 and as high as 150 with 150 being a number that SCO only claimed because one IBM email mentioned that it had 150 new customers on Linux.
Similarily to other claims, SCO brought almost no evidence to the case despite years of discovery. In fact it was often contradicted by indisputable evidence that IBM brought. For example, SCO claims that IBM damaged SCO's Unix by communicating to their third parties like their investor, Baystar, that IBM was supporting Linux and that the third parties should abandon Unix. Almost all customers third parties swore to the court that they never had communications with IBM on the topic. The only party that acknowledged it had any discussions with IBM was Hewlett-Packard and they testified that the discussion did not change their relationship with SCO so there was no damage.
The theory that SCO offered as motivation was that IBM wanted to damage SCO by hardening Linux and porting Unix code. Former SCO employees testified against SCO in that they did not believe damaging SCO was ever the motivation for supporting Linux. Their analysis was that IBM was competing against the likes of Sun and Microsoft by offering a cheaper Unix-like OS on cheaper Intel hardware that was nearly as good or better than Unix.
There are still a few claims left but at this point the pattern keeps repeating: SCO loses on summary judgements because they never had a case.
