Google recently acquired Motorola Mobility for the patents (obviously), but they haven't being doing much with it. And iOS has taken a lot of features from Android, like the notifications, folders, Siri (google voice actions is in Android 2.x) and stuff iOS copied from Google like conversational view for email. Given how one of apple's patents is 'swipe to unlock' and 'unified device search', I'm pretty sure something like 'swipe top of device down for notifications', 'sorting mail by sender and subject', 'server-based voice recognition for device-level tasks' would pass fine. Then all Google needs to do is sue Apple and get the iPhone and iPad banned. Why's Google being the victim and not counterattacking?
