RIM has been granted another patent that shows off an inovative BlackBerry keyboard. The patent, filed in 2009, is for an Angular keyboard for a handheld mobile communication device. The hardware keys in the design are angled toward the right and left from the center line in order to increase typing accuracy. It's hard to say if this would be helpful since most BlackBerry owners are darn good typists as it is, but it's still a cool idea. It's not the first time we've seen some funky patents come out of RIM, and as we know they are not abandoning the physical keyboard, we may see some more interesting designs like this down the road.
