Kyocera Added to Bluebonnet Campaign
Kyocera is the newest target in Bluebonnet Telecommunications’s ongoing litigation campaign. Kyocera phones are accused of infringing two patents that originated from Siemens (6,400,814, 6,560,274). The ’814 patent relates to silencing and incoming call and the ’274 patent relates to a transceiver device. The Bluebonnet patents were assigned to NPE, Star Co, by Siemens in July 2013 and were first asserted in litigation by Bluebonnet in June 2013. The campaign has since grown to 30 cases targeting mobile and cordless phone makers, most of which are still active. 3/19, Eastern District of Texas, 2:14cv00246

Bluebonnet Targets Phone Systems in New Wave of Filings
Bluebonnet Telecommunications expanded its campaign with eleven new suits against phone and phone system providers. Defendants include Avaya, Cisco, Grandstream, Linksys, Panasonic, Polycom, Shoretel, Toshiba, Uniden, V-Tech and Yealink. The patents-in-suit relate to call screening and equipment for determining the features assigned to a telephone, and each complaint filed by Bluebonnet alleges infringement of at least one of the two patents (5,485,511, 6,400,814). The patents originated with Siemens and were later assigned to Star Co; Bluebonnet acquired the ‘511 patent in January 2013 and the ‘814 patent in July 2013. RPX reviewed the patents as open market opportunities in 2011 and 2013. 2/18, Eastern District of Texas, 2:14cv00091, 2:14cv00092, 2:14cv00093, 2:14cv00094, 2:14cv00095, 2:14cv00096, 2:14cv00097, 2:14cv00098, 2:14cv00099; 2/19, Eastern District of Texas, 2:14cv00101, 2:14cv00102

Bluebonnet Adds Two Former Siemens Patents to Campaign
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.
