The Santa Cruz Operation Inc (the original SCO) sold its UNIX assets
to Caldera around 2001, pivoted to VDI and renamed itself to Tarantella, before being acquired by Sun, and in turn Oracle. The original SCO played no part in this.
Caldera then renamed itself to The SCO Group, and then used SCO's good name in its shakedown.
