Digital Empire Limited filed suit against AU Optronics as part of a campaign begun in July 2014 that asserts a single patent (8,081,169). The complaint accuses touch-sensitive panels manufactured by AU, and incorporated into touchscreen devices, of infringing the patent-in-suit. The asserted patent relates to a touch-capable cover lens for a mobile device. Digital Empire acquired the patent from operating company Cando Corporation in March 2014.  It has asserted it in a handful of litigations against manufacturers of touchscreen components. 9/3, Southern District of California, 3:14cv02079
