BridgeLux bites back

Maker of LED chips BridgeLux Inc (formerly eLite Opto- electronics) of Sunnyvale, Ca, USA has filed a motion to dismiss the lawsuit filed against it by Cree Inc and Boston University on September 12, 2006 alleging infringement of US patents 6,657,236 and 5,686,738.

The '236 patent, "Enhanced Light Extraction in LEDs through the Use of Internal and External Optical Elements," relates to light extraction structures used in LEDs. The '738 patent, "Highly Insulating Monocrystalline Gallium Nitride Thin Films," relates to semiconductor devices manufactured
using a gallium nitride-based buffer technology.

“We reiterate our belief that Cree’s lawsuit is without merit, and we will vigorously defend against the claims that have been brought,” said Robert C. Walker, CEO of BridgeLux.

In response to the lawsuits, BridgeLux has commenced an action seeking declaratory relief against Cree and Boston University, declaring that BridgeLux does not infringe the ‘236 and ‘738 patents, as well as certain other Cree patents. Furthermore, BridgeLux has filed suit against Cree for infringement of its US patent 6,869,812.
