IPG Photonics prevails in patent suit brought by IMRA America

Oxford. MA - IPG Photonics Corporation announces that a jury in the District Court for the Eastern District of Michigan has determined that the Company does not infringe on IMRA America's (IMRA) patent number 5,818,630 in a suit originally brought by IMRA in 2006. 

In its ruling, the jury found that the Company did not infringe on the claims asserted by IMRA. To reach this verdict, the jury heard testimony from two of the inventors of the '630 patent, experts in lasers, amplifiers and optics, and employees from both IPG and IMRA. The testimony and evidence put forth to the jury failed to prove that IPG in any way infringed. 

"For IPG, I am happy to report we have successfully defended the claims asserted against IPG by IMRA in the lawsuit," said IPG Chairman and Chief Executive Officer Valentin Gapontsev. "We will continue to aggressively defend IPG against claims relating to intellectual property." 

IPG (www.ipgphotonics.com) is the world leader in high-power fiber lasers and amplifiers. Founded in 1990, IPG pioneered the development and commercialization of optical fiber-based lasers for use in a wide range of applications such as materials processing, advanced, telecommunications and medical.
