Valve wins legal battle against patent troll Rothschild and associated companies

Patents give an incentive to actually do the R&D for new products and projects? How would you feel if you spent millions of dollars and 15yrs designing a product and then some random dude just buys one, reverse engineers it and undercuts you? It basically disincentivizes anyone from doing any innovation since the game theory would be to just wait for someone else to do it and then take it for your own.
