Anyone have an estimate of how much revenue increase the patent office received as a result of allowing software patents while knowing nothing at all, whatsoever about software? How many of the things have been granted? How many filed? How much are the filing fees? How much are typical lawyering fees for it. There are many among us who feel it is the actions of pure parasites on genuine tech innovation in software and systems so it's a question of how much was gouged by that decision (intentionally or otherwise). The other one that could be interesting to know is the descriptive stats on salaries for patent attourneys specialising in software vs people being paid to program software.
