Not long ago, the SCO group sued IBM after claiming that it had violated IBM’s Unix licenses in the development of Linux code under IBM.

The U.S. Bankruptcy Court for the District of Utah, which is responsible for SCO’s bankruptcy, recently announced that SCO’s debtors, represented by TSG Group, have reached an agreement with IBM and have settled all remaining claims between the two companies.

Xinuos, the company that acquired SCO’s Unix products and intellectual property a decade ago, sued IBM and open solutions provider Red Hat last March for allegedly illegally copying Xinuos software code for its server operating systems.

The affected operating systems were OpenServer and Unixware, both of which still have significant customers. When Xinuos made the acquisition, then-CEO Richard Bolandz assured that the company did not intend to pursue lawsuits against all SCO Group assets included in the deal.

Xinuos also claims that IBM is seeking to sabotage FreeBSD, an operating system used to run modern servers, desktops, and embedded platforms, a burden many experts have placed on IBM. Moreover, the company is demanding that the court reject IBM’s $34 billion acquisition of Red Hat.
