SynQor To Take Several Competitors To Trial For Patent Infringement
The Federal Court in the Eastern District of Texas is once again the locus of patent infringement litigation in the power electronics industry. SynQor announced that it has filed a lawsuit against several of its competitors for infringement of three patents relating to bus converters and/or non-isolated point of load converters used in intermediate bus architectures.
The defendants in the action are Artesyn Technologies, Inc., Astec America, Inc., Emerson Electric, Co., Bel Fuse Inc., Cherokee International Corp., Delta Electronics, Inc., Delta Products Corp., Murata Manufacturing Co., Ltd., Murata Electronics North America, Inc., Power-One, Inc., Tyco Electronics Corp., and Tyco Electronics Ltd..
U.S. Patent No. 7,072,190 (titled "High Efficiency Power Converter"), issued July 4, 2006, details a power converter that "nearly losslessly delivers energy and recovers energy from capacitors associated with controlled rectifiers in a secondary winding circuit, each controlled rectifier having a parallel uncontrolled rectifier." U.S. Patent No. 7,269,034 (titled "High Efficiency Power Converter"), issued September 11, 2007, also covers similar subject matter.
U.S. Patent No. 7,272,021 (titled "Power Converter with Isolated and Regulated Stages") issued September 18, 2007, details the process in which, in a power converter, "the duty cycle of a primary winding circuit causes near continuous flow of power through the primary and secondary winding circuits during normal operation."
SynQor alleges that the past and continued acts of infringement have caused injury and therefore the company states that it is entitled to recover compensatory damages in an amount subject to proof at trial. In addition, SynQor alleges that "defendants’ infringement of the patents-in-suit has been and/or will continue to be willful and deliberate, entitling SynQor to increased damages."
SynQor is seeking treble damages, interest, costs, fees and other relief that the court may deem to be appropriate.
