On August 10, 2007, the United States District Court in Utah issued a ruling that Novell had retained copyright ownership of the System V UNIX copyrights and that SCO was in breach of its covenants to provide Novell with the previously agreed royalties to the Unix technology Novell had originally sold to SCO. Following this ruling, the value of SCO stock fell to just $0.44 per share, a one-day drop of more than 70%. On September 14, 2007, SCO filed for Chapter 11 bankruptcy protection, and by September 18 its share price had reached $0.18 per share.
