On September 11, 2006, Cree announced the filing of a patent infringement suit in MD NC against BridgeLux (formerly eLite Optoelectronics) over patents relating to light extraction structures used in light emitting diodes and semiconductor devices manufactured using a gallium nitride-based buffer technology.
Once again, we have a Bayh-Dole aspect to patent litigation. The gallium-nitride-related patent is owned by the Trustees of Boston University and licensed to Cree on an exclusive basis, Cree said. Boston University is a named plaintiff in the suit. This patent, titled "Highly Insulating Monocrystalline Gallium Nitride Thin Films," was invoked in two prior suits brought by Cree and Boston University against Nichia Corporation and AXT Inc.
