Sam has some interesting details about another possible patent troll in the making. It has links with Microsoft.

IP Innovations is not the first company of its kind which has Microsoft ex-employees - Nathan Myhrvold, for many years a senior Microsoft employee, runs an outfit called Intellectual Ventures, a company devoted to buying potentially profitable patents.

Recall Acacia's own ties with Microsoft and be aware of the ongoing research at Groklaw. There could be more than a single "next SCO".
