And then? What do you propose is the next logical step once you have the list of patents you infringe on? Go to Microsoft and say "please sue us now"? Because if you were going to suggest that they re-develop in order to avoid infringing any patents, you're either from another planet or a troll.
Then nothing. You should expect this. If the court sets a fine, you should pay it.
EDIT: I'm not trolling, nor I would ever want to do so. It's just that people here are forgetting how the system works (you're a hacker, find your way out). See last paragraph http://news.ycombinator.com/item?id=1363080
