SCO, a company which once claimed to own the rights to the Unix operating system and all Linux derivatives, is, unsurprisingly, one step closer to its deathbed. Nasdaq has sent a notice that they will be delisted from the exchange. Refusing to admit the fight is over, SCO will appeal the delisting. But with its cases against IBM and Novell in tatters, a bankruptcy filing, and dwindling cash reserves, the persistent litigator is unlikely to reverse Nasdaq's decision, which comes after after earlier warnings from the exchange.
