So much for the "Microsoft doesn't have a history of patent lawsuit trolling. [...] At the end of the day MS is a developer centric company, they pride themselves on the ability to make things, and patents are an annoying side show to that." argument found here: http://news.ycombinator.com/item?id=1745932
Patents are a big deal at Microsoft. They are highly encouraged. Employees who succeed in securing a patent receive a plaque that is proudly displayed in their office as well as a nice bonus.
Not sure if you are being sarcastic or not, but I certainly am.
