Yeah, now you say that the patent system is wrong, until you create something great and someone else just takes it and makes huge money with it. I bet this would change your view 180 degrees. Microsoft infringed many patents, in most situations they just shut up other (usually small) companies with money and the case never makes it to the public, the only moments you hear about it is when someone is not smart enough to use the "we'll go public unless you pay us" and thinks that taking the case to the court will earn them more. I think that Microsoft (but this applies to most really big companies) thinks of this as a way of buying the code or solutions. It would probably cost them more to develop it on their own, so they just take the ready solutions and shut everyone up with cash. $200m is pocket money for them and they have some really good lawyers.
