How are any of these patents valid, especially in application to mobile application technology? I'm not a lawyer; I'm seriously baffled as to how any of them, in application to mobile "pay to upgrade" (or any other "customer interaction") flows, aren't obvious. It's the first thing I thought of when I first thought to write a mobile application and how to make money off of it.
