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
