Plot thickens. If you're right, it's Microsoft who holds the keys to making a free-of-charge OpenGL 3 implementation on that part. Would be rather hilarious.

The Wall Street Journal is reporting that a group of open-source backers is poised to purchase 22 graphics patents formerly the property of Microsoft. The patents in question seem to include some or all of the 3D-graphics-related ones that Microsoft purchased from SGI in 2002.
