SCOsource is a business division of The SCO Group that manages its (now legally voided) Unix intellectual property. The term SCOsource is often used for SCO's licensing program that allows corporate users of Linux to buy licenses to proprietary Unix technology that SCO claims exists in the Linux operating system. A single CPU license costs $699 (USD).
On July 21, 2003, SCO announced that it intends to sell binary-only licences to use the free Linux operating system which will remove the threat of litigation from licence-holders. Linux advocates reacted by stating that SCO has no basis for this action, as their claims were still disputed in court, and that the terms of the GPL seemed to indicate that doing this may cause SCO to forfeit their rights to distribute Linux or Linux-derived code in any form.
On August 5, 2003, SCO's Darl McBride announced the company's final licensing fees requested from end users for the use of Linux; a single-CPU server license will cost US $699 until October 15, 2003, and $1,399 afterward, while licenses for desktop and embedded systems will currently cost US $199 and US $32, respectively. 1 2 Prices for server systems with more than one CPU range from US $1,149 for two CPUs to US $2,499 for four CPUs and US $4,999 for eight CPUs, with each additional CPU being priced at US $749. All of these prices, including the ones for desktop and embedded systems, were scheduled to be increased on October 15, 2003, but as of January 2005, the prices have remained the same.
