Beginning in 2003, The SCO Group was involved in a dispute with various Linux vendors and users.
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.
