But even Microsoft's childlike "that's mine" attitude about intellectual property and patent violation claims against open source doesn't explain the company's resistance to Red Hat. The question to ask: Whose intellectual property rights is Microsoft seeking to protect?

Far from being the evil monopolist, Microsoft has in many ways become the cooperative giant—and it's all thanks to intellectual property. The company's IP czar takes us inside the corporate transformation in a new book, Burning the Ships, to show us how it happened (and to take a few potshots at Richard Stallman).

Microsoft's aggressive defense of its intellectual property, which includes claims that Linux violates a number of its patents, is nothing more than "a marketing thing," according to Linus Torvalds, creator of the Linux kernel.

"When Microsoft announced the first of its patent interoperability agreements with Novell in November 2006, one of the major claims made in favor of the patent covenant agreement was that it would give customers peace of mind and ensure that they didn’t have to worry about issues such as intellectual property infringement."

One of the enduring soap operas this year has involved the ongoing patent infringement threats by Microsoft against “Linux, OpenOffice, email, and other open source software.” According to Microsoft, 235 of its (unnamed) patents are being infringed, and it should be entitled to be paid for this use of its intellectual property.

Microsoft tried to auction off some patents that they claim relate to Linux. Patent trolls could have bought them. Instead Open Invention Network (OIN) got them. Why would Microsoft wish to get rid of 22 patents that it presumably could sue Linux over? Let's try to imagine what might have happened.

Microsoft CEO Steve Ballmer has once more claimed that Linux and open source violates Microsoft's intellectual property and patents. Canonical's CEO Mark Shuttleworth thinks Ballmer has it all wrong.

It is reported that Microsoft recently obtained patent for "Operating System Shutdown". In simpler words, Microsoft now holds the intellectual property rights for 'shutting down an operating system'.
