Bluebonnet Targets Phone Systems in New Wave of Filings

February 20, 2014

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 (5,485,5116,400,814). 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,  2:14cv000912:14cv000922:14cv000932:14cv000942:14cv000952:14cv000962:14cv000972:14cv000982:14cv00099; 2/19, Eastern District of Texas, 2:14cv001012:14cv00102
