A Texas shell company says Apple and others have infringed on technology for basic smartphone gestures like dragging and “double tap.” The patents were issued in 2007 to a Taiwanese maker of touchpad technology.
In lawsuits filed this week, a shell called “Touchscreen Gestures” claims devices like the iPhone, the iPad and the Blackberry Playbook are infringing on its technology. A related suit accuses Samsung’s Galaxy tablet of violating the same patents.
The patents are US Patent 7190356 (“A method of identifying double tap gesture”), US Patent 7180506 (“A method for identifying a movement of single tap 7180506) and US Patent 7184031 (“A method identifying a drag gesture”).
