WOODBURY, N.Y., July 12, 2013 (GLOBE NEWSWIRE) -- Research Frontiers Inc. (Nasdaq:REFR), the developer and licensor of SPD-Smart light-control technology has filed a lawsuit against E Ink Corporation; E Ink Holdings, Inc. (f/k/a Prime View International Co., Ltd.); Amazon.com, Inc.; Sony Electronics Inc.; Sony Corporation; Barnes & Noble, Inc.; and Barnesandnoble.com LLC in the United States District Court for the District of Delaware for patent infringement. Research Frontiers seeks an injunction in addition to monetary damages and pre-judgment interest and other relief.
In this lawsuit, Research Frontiers asserts infringement by the named defendants of United States Patent No. 6,606,185, entitled "SPD Films and Light Valves Comprising Liquid Suspensions of Heat-Reflective Particles of Mixed Metal Oxides and Methods of Making Such Particles," and United States Patent No. 5,463,491, entitled "Light Valve Employing a Film Comprising an Encapsulated Liquid Suspension, and Method of Making Such Film."
"A team of scientists and other dedicated individuals have worked for decades and Research Frontiers has invested approximately $90 million to develop SPD-Smart light-control technology," noted Joseph M. Harary, President and CEO of Research Frontiers. "Over 40 companies around the world, including many of the world's leading chemical and glass companies, have recognized the value of our intellectual property and entered into license agreements with us. Many of these companies are using our technology to commercialize products in a number of industries including the automotive, aircraft, architectural, marine and museum markets, and these licensees and their customers in turn have built substantial businesses around our technology and made SPD-Smart light-control technology the world's best-selling smart window technology. We believe that it is unfair to us, to our licensees, and to their customers, when companies infringe upon our intellectual property rights, and we are asking the court to stop such infringement by the defendants and compensate us with substantial monetary damages."
