Latest Results Concerning IMRA/Coherent Patent Litigation

By October 2, 2015News

Yesterday, on October 1, 2015, in a nullity proceeding, the German Federal Patent Court (Bundespatentgericht) found the German patent 695 00 997.4 (the German Part of the European Patent 0 754 103) to be invalid. This patent is a German counterpart of the fundamental U.S. patent (U.S. Patent 5,656,186) filed in 1994, assigned to The Regents of the University of Michigan, Ann Arbor, Michigan, and invented by a team at the University of Michigan’s Center for Ultrafast Optical Science (CUOS). IMRA America Inc. is an Exclusive Licensee in non-biologic field of use of the Patent from the University of Michigan.

The basic U.S. ‘186 patent has long been found to be valid in several U.S. Patent Office Proceedings and is fundamental to the field of material processing with ultra-short pulsed lasers. The advanced technology disclosed in the patent relates to complex laser interaction with materials to achieve breakthrough performance in laser-based micromachining applications, resulting in extraordinary precision and material processing quality.

IMRA America has, for many years, taken all actions necessary to protect the patented technology as well as their own licensing rights and the rights of their licensees. IMRA strongly disagrees with the decision of the German Court and is considering their options to appeal the case.
