The IP wars

Microsoft, Apple, Cisco, IBM, Google, and Facebook all do it. I don't mean innovate, though they do that, I mean sue each other for some piece of code they wrote once, and recieved patents for. It could be a big problem going forward for the things that these companies are know for, namely innovation. Mostly, I blame the stupidity of our patent system. We really should try to prioritize and rationalize the system.
