Amazon’s Customer Support Service Accused of Infringing LT Tech Patent

June 19, 2014

LT Tech filed suit against Amazon as part of its campaign asserting patent 6,177,932. The campaign launched in 2013 and has targeted a dozen defendants, including Dell, Frontrange Solutions, and Quest Software. The patent-in-suit relates to network-based customer service and was previously asserted by IPNav subsidiary Gemini IP. It originated with Netdialog Inc., which later merged with Kana Software. Kana transferred the patent to IPNav controlled Polaris IP in March 2007.  A month after the assignment a separate suit filed by Polaris IP against Kana was dismissed due to settlement. Around that time the patent-in-suit was transferred from Polaris to Gemini. In 2013  it was transferred again, from Gemini to LT. The asserted patent has been reexamined and in 2010 claims 1-9, 11-13, and 19 were cancelled, claim 10 was amended, and claims 20-64 were added. In the complaint, Amazon’s remote support service, included on its devices, is accused of infringing the asserted patent. 6/16, Eastern District of Texas, 4:14cv00392
