Since what I propose amounts to for the most part AMD and nVidia leaving their D3D code in when they compile drivers for Linux, and perhaps some shim with X, the companies involved would be doing little if anything /new/ that they could be sued over, and the rest of the implementation would be too drastically different for a 'good' patent to really be applicable.
    Do you seriously MS worries about bad PR on a lawsuit? They have sued and successfully won over the name "Lindows" for crying out loud. Who are they gonna tick off if they do? The same people that are already ticked off at them, it wouldn't hurt them in the least.

    BTW:

    "In 1981, the Supreme Court stated that "a claim drawn to subject matter otherwise statutory does not become nonstatutory simply because it uses a mathematical formula, computer program, or digital computer" and a claim is patentable if it contains "a mathematical formula [and] implements or applies the formula in a structure or process which, when considered as a whole, is performing a function which the patent laws were designed to protect"."

    This is exactly the reason why commercial distro's do not include libraries such as lame and mad into their official distros.

    'Lindows' was asking for it, they got it, and no one cared.
    The day Crysis runs on Linux is the day MS market share goes out the window.

    The UN and anyone else who is demanding that microsoft improve interoperability. There are very real fines for noncompliance, and going out of their way to /stop/ windows 3d applications from interoperating with other operating systems would be very likely to not help their cause against those fines.

    When it comes to 3D api interoperability MS does already offer that by supporting openGL. If your going to sue someone you would have to sue the game developers.

    Unless I'm mistaken, Vista pipes OpenGL through Direct3D in Vista, severely degrading its performance. This makes OpenGL a ton less attractive to game developers. You can't turn around and blame /them/ for not supporting it under conditions like that.

    Well you would be wrong.

    How exactly would microsoft stop AMD and nVidia from leaving Direct3D support in their drivers when they compile them for linux?

    Easy, it is a licensed technology of Microsofts. Microsoft is able to dictate what the terms of what that license is. Microsoft would have to follow basically that SGI did when it went from Iris GL to openGL.

    Interesting. Why aren't they going after WINE, CrossOver, and Cedega?

    At anytime they can, in fact those items were singled out as exceptions in the Novell/MS deal. Those apps at present are just not a threat to MS right now in their present form.

    Technically, it's only Wine, and VMware has it's own too. They're not recreating the API, the putting D3D through OpenGL. Pretty much the exact opposite of what you thought Microsoft was doing with Vista.
    Doing it this way through a wrapper doesn't violate any patents(at least to my knowledge.), but it's much less effective. Maybe if AMD and Nvidia also pitched in their efforts into Wine's D3D wrapper development would go faster, but I don't think they really care.
