You forget the other major product Caldera had: it got DR DOS from Novell. Alongside with it it got a court case against Microsoft. So Caldera is no strage to courts (Recall that in 2000 old SCO was renamed Tarantella and in 2002 Caldera was renamed SCO). That said, Darl McBride only got there in 2002. But Ralph Yarro has been at the Canopy Group since 1995.
