On July 23, 1996, Novell sold the intellectual property of Digital Research to Linux vendor Caldera. The common thread the two companies had was Ray Noorda. Noorda had been CEO of Novell and was Novell’s largest shareholder, and Caldera was part of Noorda’s Canopy Group, where he incubated startups. The very next day, Caldera filed a lawsuit against Microsoft, accusing it of violating sections 1 and 2 of the Sherman Anti-Trust Act.
