The patent system is like a bug in a software that all your clients rely upon and will never let you fix. I expect peace in the middle east to happen before the patent system gets scrapped.
There's still a huge valid question about reform as opposed to scrap. The system would work if it was actually applied correctly. (I understand application is part of said system, but I'm referring to the overall human aspect, ie, the reason AskPatents.com was made.)
But askpatents.com looks to me like it has some potential to work, and if it did, it might solve at least most of the really heinous examples. I'd say that at least merits making the possibility of reform an open question.
Forcing a massive shift in IP rights (that may not benefit large, entrenched interest) through Congress is an enormous undertaking that may not succeed. Reform may be a more practical option.
