This meant that a 2007 judgement, that had already given Novell ownership of these same copyrights, had to be set aside.
The case has been going for almost six years. It was filed in 2004 by SCO after Novell asserted its rights to the UNIX copyrights.
Novell's action, in May 2003, came after SCO had filed a case against IBM in March 2003, claiming that IBM had violated contractual obligations it had with SCO by contributing UNIX code to Linux.
SCO based its case against IBM on a claim that it had purchased the UNIX rights from Novell in 1995; this led to Novell's claim and, subsequently, SCO's suit.
In a statement overnight, Novell said it was "very pleased with the jury's decision confirming Novell's ownership of the Unix copyrights, which SCO had asserted to own in its attack on Linux. Novell remains committed to promoting Linux, including by defending Linux on the intellectual property front.
"This decision is good news for Novell, for Linux, and for the open source community."
