Novell later sold its business of licensing and supporting [[System V]] Unix (the direct descendant of the original AT&T Unix) to [[The Santa Cruz Operation]], commonly called "SCO"; exactly which rights were sold, and whether the copyright itself was sold, is part of the dispute in the [[SCO v. Novell]] lawsuit.  In 2000, [[Caldera Systems]] purchased the server software division of SCO, which then changed its name to [[Tarantella]].  In 2002, Caldera changed its name to [[The SCO Group]].

In 2003, SCO filed lawsuits against [[IBM]], [[Autozone]] and [[Daimler-Chrysler]] for using Linux, an open source clone of Unix developed for the PC by [[Linus Torvalds]] and others over [[USENET]].  Simultaneously, SCO declared it was entitled to a license fee of $699 for every copy of Linux in use anywhere.  Novell in turn sued SCO for slander of title and ordered SCO to drop the suits.  All of these court actions are still moving through the federal legal system in Utah.

If SCO wins, millions of Linux users will be liable for licensing fees, potentially bankrupting all but the wealthiest users.

Today, the main AT&T branch of Unix is nearly irrelevant, having been eclipsed by the Unix-like [[Linux]] operating system and the various [[BSD]] derivatives.  [[Sun]]'s [[OpenSolaris]] and [[HP]]'s [[HP-UX]] are the only offshoots of [[SVR4]] still in development and widespread use.
