Other than that I can only conclude that those who reside at the CAFC bench are ill equipped to deal with patent litigation and don't know what the hell they are doing!
All you have to do is look at Prost's work history to see she was never qualified and likely never will be. I doubt she ever knew anything about patents until GW Bush appointed her to the CAFC. And it's not just her, there are many others there without any background in patents. As long as stupid decisions continue to be made by politicians what can we expect?
