Several months after Mobile Telecommunications Technologies, LLC (MTel) lost its first suit against Samsung, the entity filed a second suit (2:15-cv-00183) that asserts a different group of patents. The complaint asserts six patents, all of which have been previously used in MTel’s litigation campaign (5,581,804; 5,590,403; 5,659,891; 5,754,946; 5,809,428; 5,915,210). At issue in this case are Samsung’s devices, including smartphones, TVs, and wearables, that run operating systems with messaging applications or services. The complaint also mentions MTel’s trial win over Apple in November 2014 as evidence of infringement. Specifically, it notes that features in Samsung’s devices are similar to features in Apple devices that were found to infringe MTel’s patents.
