SCO Company History

Website 2007 SCO (Santa Cruz Operation) was founded in 1979 of the both brothers Doug and Larry Michels who developed the UNIX derivative SCO UNIX for Intel computers. The enterprise went to stock exchange 1993 under the name SCOC. SCO bought all rights at the AT&T UNIX source code as well as UnixWare 2 of Novell in 1995 which purchased the UNIX source code together with the technology and rights by AT&T at the operating system UnixWare before. Novell takes about 17% of the SCO shares, SCO licenses the network technology from Novell in return and HP develops a 64 bit version of UNIX.

1999 had SCO sales offices in approximately 80 countries. SCO showed the next company plan at the "Forum 2000" after the sale of the UNIX business to the Linux company Caldera. The left bussiness division of SCO was renamed in Tarantella Incorporated. The line of business is aligned to the development and sale of the web middleware Tarantella. Caldera split up into the SCO Group for the complete UnixWare and Open Server operating system business. Caldera purchases all rights by the take-over at the operating system UnixWare and the associated applications with exclusive right for sale of the older Open Server system. SCO ensured further the license income which flow in the Tarantella division. About 800 employees of SCO shall change to Caldera Inc. As a selling price 7 million dollars cash as well as 28 percent of the shares, which are about 17.5 million share certificates, from this are 2 million share certificates from a reserve for employee options. In addition, the Caldera investor "The Canopy Group" has agreed to grant a credit of another 18 million dollars for SCO.

Caldera plans the disclosure of the source code of UnixWare. But copyrights of AT&T, Novell, Tandem, Compaq and SCO are still parts of it. The time for the release isn't published yet. Currently (July 2003) is the SCO Open Server 5.0.7 with enhanced hardware support and USB 2.0 support the latest release.

The SCO Group took the company IBM to court for 3 billion dollars compensation in March 2003 because of injury of an intellectual property from the former common project Monterey. It is all about more exactly that SCO has basic rights at the UNIX source code and Linux relies on UNIX architecture and APIs own copyright claims are injured. SCO wants to prove this by facts of the source code transfer between UNIX and Linux. In August 2003 IBM answered with a countersuit for reason, SCO has hurt the GPL by the Linux distribution of her own and loosed possible copyright claims through this. SCO has taken licence fees for the use of Linux which is forbidden by GPL.

Several companies were included in this court process as plaintiff or defendants. The legal discussion lasts without a clearing judgement in meanwhile for more than 3 years.
