The Apple iPad 3 and Macbook Pro, as well as other Apple products that use pulse-width modulation signals to drive light-emitting diodes, allegedly infringe four patents. The complaint in LED Tech Development, LLC v. Apple, Inc. was filed in the federal district court in Delaware on October 11, 2012.
LED Tech Development allegedly is the owner by assignment of U.S. Patent Nos. 6,095,661 (“the '661 patent”), 7,393,119 (“the '119 patent”), 6,808,287 (“the '287 patent”), and 6,488,390 (“the '390 patent”).
The '390 patent is entitled “Color-Adjusted Camera Light and Method.” The '287 patent is entitled “Method and Apparatus for a Pulsed L.E.D. Illumination Source.” The '119 patent is entitled “Method and Apparatus for Constant Light Output Pulsed L.E.D. Illumination.” The '661 patent is entitled “Method and Apparatus for an L.E.D. Flashlight.”
LED Tech alleges that Apple is infringing the four patents, literally and under the doctrine of equivalents, by making, using, selling, offering to sell, or importing, without license or authority, products utilizing pulse-width modulation signals to drive light-emitting diodes, including, but not limited to, its iPad 3 tablet device and Macbook Pro personal computer. LED Tech requests remedies including damages and injunctive relief.
The case is No. 1:12-cv-01316-UNA.
