RIM's been busy on the patent application front lately, filing off concepts for anything from smartphone docks to rotating keypads - even flirting with potential forays into forensics peripherals. Perhaps sensing the crushing need to differentiate its ailing BlackBerry brand, Waterloo's taken to the USPTO with a doc submitted last November that could do just that. The pressure-sensitive input scheme and touchscreen interface described therein would respond to a user-set pattern of force by granting access to a handheld device's features and applications.
