IPG Photonics wins patent suit

Ann Arbor, MI - The jury has returned a verdict of non-infringement in the case of IMRA America against IPG Photonics in a trial presided over by Senior Judge Arthur J Tarnow in the US District Court of Eastern Michigan. IPG did not challenge the validity of US Patent 5,818,630. The trial is the culmination of a five year battle wherein IMRA has pressed IPG to license their intellectual property.

Mr. Takashi Omitsu, President of IMRA America, commented on the results of the trial: “We are disappointed that the jury has not agreed with our position and has not protected our valuable patent rights. Despite this result, IMRA remains committed to protecting and enforcing its intellectual property.”

IMRA America, Inc., founded in Ann Arbor, Michigan in 1990, is dedicated to the development of ultrafast fiber laser technologies for commercial applications. IMRA’s technology portfolio includes over 150 US and international patents and patent applications. IMRA’s femtosecond fiber lasers are ideal for applications in industrial material processing.
