RIM is no stranger to lawsuits, they come and go. The latest lawsuit is aimed at not only RIM, but also Apple. It comes from a Texas shell company that is creatively named Touchscreen Patents. RIM has apparently infringed on this patent in the way that the BlackBerry PlayBook handles gestures like dragging across the screen, as well as single and double taps. These patents were originally issued in 2007 and 2008 to a Taiwanese company, and since have been transfered to Touchscreen Patents. Details on the infringement as well as the transfer of the patents is limited at this point.
