CAO Lighting, Inc. filed a patent infringement suit against Light Efficient Design, LLC and its distributor EWS in Federal Court in Boise, Idaho. The lawsuit alleged infringement of CAO Lighting’s U.S. Patent No. 6,465,961. The patent describes a method of building an LED light source with an omni-directional beam emission.
Edgar R. Cataxinos and James E. Magleby, of the intellectual property law firm of Magleby Cataxinos & Greenwood of Salt Lake City, Utah represent CAO Lighting in the lawsuit.
Previously, other parties challenged the asserted patent through re-exams at the U.S. Patent and Trademark Office.
However, a panel of patent examiners rigorously reviewed the patent claims asserted in the patent and found them to be patentable. CAO has asserted these claims in the infringement lawsuit against Light Efficient Design. Also, CAO contends that the validated claims cover multiple aspects of the structures that many LED light sources employ today.
“This patent, invented by Dr. Densen Cao, is a fundamental patent in the LED lighting industry, providing the technology for LED bulbs that emit omni-directional light. The methods taught by this patent are proven to be the most efficient way to build this type of LED light source, evidenced by the wide adaptation and use by the industry,” said Terry Jones, General Counsel of CAO Lighting, Inc.
CAO Lighting says it has established a reputation of innovation including a 360-degree light source and says its Dynasty® Omni LED products offer unique features for retrofit of high wattage and HID light sources in various applications and deliver exceptional energy savings.
