The SCO Group is involved in a dispute with various Linux vendors and users. SCO has initiated a series of lawsuits that will probably define the future of both Linux and Unix. In this campaign SCO is trying to convince the world that Linux violates some of SCO's intellectual properties. Many people are sceptical of SCO's claims, and they are strongly contested by SCO's opponents in the lawsuits, some of which have launched counter-claims.
SCO retains lawyer David Boies, announcing that they would be investigating infringement on their intellectual property pertaining to their ownership of UNIX. Over the next several months, the executives of SCO issue a number of press releases and public statements alleging unspecified violations of their UNIX intellectual property rights in Linux. They also begin to raise questions of the validity of the GPL.
SCO sues IBM over its contributions to Linux, claiming that IBM stole UNIX trade secrets and gave them to Linux kernel developers. The suit was filed originally in the Utah State Court, but was immediately removed to Federal Court.
The SCO Group says they sent letters to 1,500 of the world's largest corporations, including the Fortune 500 companies, alleging that the use of Linux may infringe a copyright they hold on the original UNIX source code. They say that the Linux kernel, the core of the operating system contains copyrighted SCO source code. In this letter they also announce the suspension of their own Linux-related activities.
The SCO Group files an amended complaint.
SCO announces that they intend to issue invoices to companies using Linux.
IBM files its counterclaims, alleging that SCO has violated the GPL, several patents, and the Lanham Act by falsely accusing IBM of violating SCO's IP rights.
SCO CEO, Darl McBride, writes an open letter to the free software community. In this letter he accuses the free software community of being responsible for recent DDoS attacks on the SCO website and once again asserts that Linux violates SCO's intellectual properties.
IBM files amended counterclaims, including a claim of copyright infringement.
BayStar Capital and Royal Bank of Canada invest $US50 million in SCO to support the legal cost of the SCOsource program.
SCO announces that it would not attempt invoicing Linux users after being threatened with mail fraud.
SCO sends a letter to all Unix licensees asking them to certify certain questions regarding the use of Linux.
SCO sends a letter claiming ownership of the Linux ABI code.
SCO sends a letter to the United States Congress, raising issues such as the economics of open source development and the legality of the GPL.
The SCO Group becomes the target of the Mydoomcomputer worm, which was programmed to launch a denial of service attack on the company's website beginning on February 1, 2004. The Group has also been the subject of a Google bomb attack. Google returns SCO's website as the number one hit for the phrase "litigious bastards."
SCO files a second amended complaint against IBM. It drops the trade secret claims, but adds claims of copyright infringement.
The Red Hat v. SCO case is stayed until resolution of the SCO v. IBM case.
IBM files motion for Partial Summary Judgment on Claim for Declaratory Judgment of Non-Infringement. This would confirm that IBM has not infringed on any SRVx code in its Linux activities.
The SCO v. Novell case is dismissed due to inadequate pleading of special damages.
The SCO v. AutoZone case is stayed pending the SCO v. IBM case.
All claims in the SCO v. DaimlerChrysler case are dismissed except on the matter of breach of section 2.05, in that DC did not submit their response in a timely manner.
SCO files an amended complaint in SCO v. Novell.
IBM files motion for partial summary judgment on Breach of Contract Claims in SCO v. IBM. This judgement would confirm that the AT&T license agreement placed no restrictions on derivative works.
IBM files motion for partial summary judgment on its counterclaim for copyright infringement in SCO v. IBM. This judgement would find SCO guilty of copyright infringement of IBM's contributions to Linux.
Novell files a motion to dismiss.
SCO v. DaimlerChrysler case is dismissed without prejudice based on stipulation of the parties. If SCO wishes to pursue the remaining claim (i.e. whether DaimlerChrysler replied in a timely manner) again, they must pay DaimlerChrysler's legal fees from August 9, 2004.
SCO's appeal of the DaimlerChrysler case is dismissed.
IBM's motions for partial summary judgment are denied without prejudice, to be refiled after the close of discovery.
Novell files its answer with the court, denying SCO's claims.
Novell files counterclaims asking the court to force SCO to turn over the revenues it had received from UNIX licenses, less a 5% administrative fee. Additionally, Novell asks the court to place the funds in a "constructive trust" in order to ensure that SCO can pay Novell since the company's assets are depleting rapidly.
Final deadline passes in SCO v. IBM to disclose allegedly misused material with specificity. SCO provides IBM with a list of 294 alleged violations.
