Linux It's strange. Microsoft has been patent trolling the heck out of the Linux kernel for a long time now, and is still using these patents against Android today in its protection money scheme. However, as illustrates, Microsoft makes quite a few contributions to the Linux kernel. Shouldn't this invalidate their patent claims?

Well, Microsoft is attacking handset makers for their use of Linux on smartphones. They are not attacking Linux developers over the contents of the kernel.

Also, their contributions are related to Hyper-V, and are completely unrelated to mobile phones.

However, if their Hyper-V related changes were adapted to make the Linux kernel run better on competing virtualization platforms, and they sued companies that distributed Linux for use on competing platforms, then, yes, their contributions should invalidate their patent claims.

Not that any claims on software patents should be valid in the first place.
