Cree Inc. announced that it has filed suit against BridgeLux Inc. (formerly eLite Optoelectronics) for infringement of U.S. Patent Nos. 6,657,236 and 5,686,738. The suit, which was filed in the U.S. District Court for the Middle District of North Carolina, seeks monetary damages and injunctive relief to prohibit BridgeLux from infringing these patents.

Cree's '236 patent, entitled relates to light extraction structures used in LEDs while the '738 patent relates to semiconductor devices manufactured using a gallium nitride-based buffer technology. The '738 patent is owned by the Trustees of and licensed to Cree on an exclusive basis, is a co-plaintiff in the suit. The '738 patent was also the subject of two prior suits brought by Cree and against Nichia Corp. and AXT Inc., both of which resulted in settlements.

"The filing of this suit demonstrates Cree's willingness to protect our R&D investments and patent rights, especially at a time when some segments of the LED marketplace act as if there are no issues with intellectual property," stated Cree chairman and CEO Charles Swoboda.
