I truly wonder how the US PTO can even grant US Patent 7,617,530 in the first place. It is not so much that Microsoft got the patent, but the fact that it was approved. Looks like the US PTO is 0wn3d by Microsoft!
Great article at Groklaw on this. Please, someone, anyone, do something to fix the US PTO.
