How on earth can you have a patent on the usage of an open standard such as XML? I'm certain the implementation that i4i uses and the implementation that Microsoft uses are completely different. It's these pathetic blanket patents. I bet if I got a patent to use XML and automobiles together, within the next 10 years I'd be able to sue someone because they decided to store internal automotive computer data into an XML structure... sad, really sad.

I doubt we'll see even a hiccup in Word sales from this though.
