Microsoft "Microsoft has placed a clutch of Silicon Graphics patents in the hands of those trying to defend Linux and open-source against trolls. The Open Invention Network has taken ownership of 22 patents covering operating systems, desktop, and browsers applications, after they were bought from Microsoft by middleman Allied Security Trust."

In point of fact Microsoft sold off these patents that it bought from SGI to a patent aggregator, Allied Security Trust, who is making them available and OIN is taking them up on it.

AST is the same company that bought a patent from SCO under the guise of Black Maple.

Reference to Black Maple is at the bottom of page 17.
