Bluebonnet Telecommunications expanded its litigation campaign this week, suing Alcatel-Lucent, Huawei, NEC CASIO, Sonim, and ZTE. The new suits not only expand the number of cases in the campaign but also the number of patents asserted. Each case asserts three patents, one that was used in the original campaign suits filed in June 2013 (5485511) and two that have not been previously asserted in litigation (6400814; 6560274). The patents all relate to various aspects of mobile devices, either device features, call screening, or transmission and receipt of signal/user information. Just as in the original cases, defendants’ smartphones are accused of infrining the patents-in-suit. All three of the asserted patents originated with Siemens and were transferred to Star Co before being assigned to Bluebonnet. Bluebonnet acquired the ‘511 patent from Siemens in January 2013. The other two patents were acquired in July 2013, after the campaign started. RPX reviewed the ‘814 and ‘274 patents in February 2013.
