LED rush making Siemens clash with LG
gold rush for LED makers. It has also spawned patent lawsuits around the globe over inventions that make lights brighter and more economical. In the U.S., patent-infringement suits involving LED technology have been filed in Connecticut over custom headlights, in Florida over marine lighting, and in North Carolina over motorcycle accessories. The largest battle pits Siemens AG's Osram unit against Korean electronics makers LG Electronics Inc. and Samsung Electronics Co. Each is trying to block the other from bringing its LEDs into the United States through four trials in Washington that began last Thursday. Lawsuits also are pending in Germany, Korea, Japan and China.
