I but they continue to say NUMA, RCU, JFS, XFS, SMP, Schedulers, are derivative works and therefore belong to them. One important quote I think was kind of ironic is that Sontag said this:

SMP? JFS? XFS? Really...?...

1.) Sequent Systems and Pyramid Systems pioneered the work in SMP and 
further,
published how they did it. If anything, SCO cloned the published works. 
Also, IBM
had "SMP" machines before SCO was even a blip on the map: IBM S370 S/380 
had
multiple processors (Although, back then they called them "Engines").

2.) JFS is not a derivative of ANYTHING SCO has ever owned. As a matter 
of fact,
back when IBM first began selling RS/6000, the biggest problem in the 
entire architecture
was that the file system was not journeled. It took from 1988 until 1992 
(Or was it 93?)
until journaling was implimented. They wrote the whole thing themselves 
(I am sure
of this... At that time, I knew a lot of people at IBM Austin...).

3.) XFS has been around FOREVER. In addition, if anything, JFS is 
modeled after XFS (Although XFS is the fast file system in UNIX).

This is laughable (If it were not so serious...)
