Facebook Twitter LinkedIn Email
IMRA America Inc. of Ann Arbor, Mich., has filed a patent infringement suit in Germany against two Germany-based subsidiaries of laser maker Coherent. The patent relates to using picosecond and femtosecond lasers to micromachine parts used for microelectronics applications. The lawsuit, filed at the District Court of Düsseldorf, Germany, asserts that certain laser products marketed by Coherent’s German subsidiaries, Coherent Kaiserslautern GmbH (formerly Lumera Laser GmbH) and Coherent (Deutschland) GmbH, infringe the German part of Imra’s European Patent 0 754 103 B1, a “method for controlling configuration of laser-induced breakdown and ablation.”
