Microsoft's employees like to flap their lips about Linux violating patents, but they seem to know they have nothing that would actually stand up in court. They claim that there are at least 235 Microsoft patents that are being violated. Somehow they came to the conclusion that the Linux kernel alone violates 42 patents. That's probably the worst insult I've heard in a long time. How is it that the Linux kernel, which works completely different and more efficient than Windows, violates their patents. It sounds like a case of jealousy to me.
Microsoft, if you're going to sue me, do it already! I use many different distros, including openSUSE, Fedora, Ubuntu, Mint, Slax, PCLinuxOS, Sabayon, etc. I have a test partition on my drive just to test out different distros. I don't see how you can exclude one distro or the other in a lawsuit. If you're going to sue one, you need to sue them all. The different distros may use one program or the other that's different, but they all use the Linux kernel, which you claim violates 42 of your patents. (what a bunch of shit) And the majority of the distros use either gnome or kde, which evidently violate another 65 patents. So, how can you target one distribution (Redhat, for example), and say that they violate your patents. It's an all or nothing situation with Linux.
