As if life wasn't complicated enough for Apple Computer, now SCO is investigating the potential for intellectual copyright infringement, specifically concerning Linux companies, Apple Computer, Microsoft, BSD versions of Unix, and other companies using the various operating systems.

But as noted in the article:

A 1995 lawsuit set up barriers between the version of Unix that stemmed from AT&T and a variant that it spawned at the University of California's Berkeley campus. That Berkeley variant has spread into several operating systems, including BSD/OS, FreeBSD, NetBSD and OpenBSD. And parts of that BSD code have popped up elsewhere, including in the networking software of older versions of Windows and, more recently, as a foundation for Apple's Mac OS X.

The subsystem of MacOS X is and has always been BSD Unix, I am hoping that this suit will be thrown out, or not pursued. One interesting fact to note, in the aforementioned article it states that if you "pull down" OS X, which I can only assume means pull from the CVS tree, "You'll see a lot of copyright postings that point back to Unix Systems Laboratories, which is what we hold."

Now I wonder how many of those are from the BSD code, that still must retain copyright statements from before the 1995 decision that declared that BSD was an autonomous system?

It is my understanding that the 1995 decision pretty much makes it clear that BSD Unix does not infringe on the Intellectual property of the AT & T flavor; so how can anything derived from that variant (BSD) infringe upon said USL rights?
