SCO Group, Inc. v. International Business Machines Corp., commonly abbreviated as SCO v. IBM, is a civil lawsuit in the United States District Court of Utah. The SCO Group asserted that there are legal uncertainties regarding the use of the Linux operating system due to alleged violations of IBM's Unix licenses in the development of Linux code at IBM. The lawsuit was filed in 2003, it has lingered on through the bankruptcy of SCO Group and the adverse result in SCO v. Novell, and was reopened for continued litigation by order of a new judge on June 14, 2013. Pursuant to the court order reopening the case, an IBM Motion for Summary Judgment was filed based upon the results of the Novell decision. On December 15, 2014, the judge granted most of IBM's motion, thereby narrowing the scope of the case, which remained open. On March 1, 2016, following a ruling against the last remaining claims, the judge dismissed SCO's suit against IBM with prejudice. SCO filed an appeal later that month. In February 2018, as a result of the appeal and the case being partially remanded to the circuit court, the parties restated their remaining claims and provided a plan to move toward final judgement.
The SCO Group was an American software company in existence from 2002 to 2012 that became known for owning Unix operating system assets that had belonged to the Santa Cruz Operation, including the UnixWare and OpenServer technologies, and then, under CEO Darl McBride, pursuing a series of high-profile legal battles known as the SCO-Linux controversies.
Groklaw is a website that covered legal news of interest to the free and open source software community. Started as a law blog on May 16, 2003, by paralegal Pamela Jones ("PJ"), it covered issues such as the SCO-Linux lawsuits, the EU antitrust case against Microsoft, and the standardization of Office Open XML.
UnixWare is a Unix operating system. It was originally released by Univel, a jointly owned venture of AT&T's Unix System Laboratories (USL) and Novell. It was then taken over by Novell. Via Santa Cruz Operation (SCO), it went on to Caldera Systems, Caldera International, and The SCO Group before it was sold to UnXis. UnixWare is typically deployed as a server rather than a desktop. Binary distributions of UnixWare are available for x86 architecture computers. UnixWare is primarily marketed as a server operating system.
In a series of legal disputes between SCO Group and Linux vendors and users, SCO alleged that its license agreements with IBM meant that source code IBM wrote and donated to be incorporated into Linux was added in violation of SCO's contractual rights. Members of the Linux community disagreed with SCO's claims; IBM, Novell, and Red Hat filed claims against SCO.
Red Hat v. SCO is a lawsuit filed by Red Hat against The SCO Group on August 4, 2003. Red Hat was asking for a permanent injunction against SCO's Linux campaign and a number of declaratory judgments that Red Hat has not violated SCO's copyrights.
SCO v. Novell was a United States lawsuit in which the software company The SCO Group (SCO), claimed ownership of the source code for the Unix operating system. SCO sought to have the court declare that SCO owned the rights to the Unix code, including the copyrights, and that Novell had committed slander of title by asserting a rival claim to ownership of the Unix copyrights. Separately, SCO was attempting to collect license fees from Linux end-users for Unix code through their SCOsource division, and Novell's rival ownership claim was a direct challenge to this initiative. Novell had been increasing their investments in and support of Linux at this time, and was opposed to SCO's attempts to collect license fees from Novell's potential customers.
Beginning in 2003, The SCO Group was involved in a dispute with various Linux vendors and users. SCO initiated a series of lawsuits, the most known of which were SCO v. IBM and SCO v. Novell, that had implications upon the futures of both Linux and Unix. SCO claimed that Linux violated some of SCO's intellectual properties. Many industry observers were skeptical of SCO's claims, and they were strongly contested by SCO's opponents in the lawsuits, some of which launched counter-claims. By 2011, the lawsuits fully related to Linux had been lost by SCO or rendered moot and SCO had gone into bankruptcy. However the SCO v. IBM suit continued for another decade, as it included contractual disputes related to both companies' involvement in Project Monterey in addition Linux-related claims. Finally in 2021 a settlement was reached in which IBM paid the bankruptcy trustee representing what remained of SCO the sum of $14.25 million.
SCOsource is a business division of The SCO Group that managed its Unix intellectual property. The term SCOsource is often used for SCO's licensing program that allowed corporate users of Linux to buy licenses to proprietary Unix technology that SCO claimed exists in the Linux operating system. A single CPU license costs $699 (USD).
Project Monterey was an attempt to build a single Unix operating system that ran across a variety of 32-bit and 64-bit platforms, as well as supporting multi-processing. Announced in October 1998, several Unix vendors were involved; IBM provided POWER and PowerPC support from AIX, Santa Cruz Operation (SCO) provided IA-32 support, and Sequent added multi-processing (MP) support from their DYNIX/ptx system. Intel Corporation provided expertise and ISV development funding for porting to their upcoming IA-64 CPU platform, which was yet to be released at that time. The focus of the project was to create an enterprise-class UNIX for IA-64, which at the time was expected to eventually dominate the UNIX server market.
The history of Unix dates back to the mid-1960s, when the Massachusetts Institute of Technology, AT&T Bell Labs, and General Electric were jointly developing an experimental time-sharing operating system called Multics for the GE-645 mainframe. Multics introduced many innovations, but also had many problems. Bell Labs, frustrated by the size and complexity of Multics but not its aims, slowly pulled out of the project. Their last researchers to leave Multics – among them Ken Thompson, Dennis Ritchie, Doug McIlroy, and Joe Ossanna – decided to redo the work, but on a much smaller scale.
Ancient UNIX is any early release of the Unix code base prior to Unix System III, particularly the Research Unix releases prior to and including Version 7.
Caldera OpenLinux (COL) is a defunct Linux distribution. Caldera originally introduced it in 1997 based on the German LST Power Linux distribution, and then taken over and further developed by Caldera Systems since 1998. A successor to the Caldera Network Desktop put together by Caldera since 1995, OpenLinux was an early "business-oriented distribution" and foreshadowed the direction of developments that came to most other distributions and the Linux community generally.
In Unix computing, lxrun is a compatibility layer to allow Linux binaries to run on UnixWare, SCO OpenServer and Solaris without recompilation. It was created by Mike Davidson. It has been an open source software project since 1997, and is available under the Mozilla Public License. Both SCO and Sun Microsystems began officially supporting lxrun in 1999.
DistroWatch is a website which provides news, distribution pages hit rankings, and other general information about various Linux distributions as well as other free software/open source Unix-like operating systems. It now contains information on several hundred distributions and a few hundred distributions labeled as active.
In the 1950s and 1960s, computer operating software and compilers were delivered as a part of hardware purchases without separate fees. At the time, source code, the human-readable form of software, was generally distributed with the software providing the ability to fix bugs or add new functions. Universities were early adopters of computing technology. Many of the modifications developed by universities were openly shared, in keeping with the academic principles of sharing knowledge, and organizations sprung up to facilitate sharing. As large-scale operating systems matured, fewer organizations allowed modifications to the operating software, and eventually such operating systems were closed to modification. However, utilities and other added-function applications are still shared and new organizations have been formed to promote the sharing of software.
Linux began in 1991 as a personal project by Finnish student Linus Torvalds to create a new free operating system kernel. The resulting Linux kernel has been marked by constant growth throughout its history. Since the initial release of its source code in 1991, it has grown from a small number of C files under a license prohibiting commercial distribution to the 4.15 version in 2018 with more than 23.3 million lines of source code, not counting comments, under the GNU General Public License v2 with a syscall exception meaning anything that uses the kernel via system calls are not subject to the GNU GPL.
Unix is a family of multitasking, multi-user computer operating systems that derive from the original AT&T Unix, whose development started in 1969 at the Bell Labs research center by Ken Thompson, Dennis Ritchie, and others.
Xinuos is an American software company that was created in 2011 and was first called UnXis until assuming its current name in 2013. Xinuos develops and markets the Unix-based OpenServer 6, OpenServer 5, and UnixWare 7 operating systems under SCO branding. Xinuos formerly sold the FreeBSD-based OpenServer 10 operating system.
SCO Forum was a technical computer conference sponsored by the Santa Cruz Operation (SCO), briefly by Caldera International, and later The SCO Group that took place during the 1980s through 2000s. It was held annually, most often in August of each year, and typically lasted for much of a week. From 1987 through 2001 it was held in Santa Cruz, California, on the campus of the University of California, Santa Cruz. The scenic location, amongst redwood trees and overlooking Monterey Bay, was considered one of the major features of the conference. From 2002 through 2008 it was held in Las Vegas, Nevada, at one of several hotels on the Las Vegas Strip. Despite the name and location changes, the conference was considered to be the same entity, with both the company and attendees including all instances in their counts of how many ones they had been to.
