Lately, Siemens has filed a lawsuit with Samsung and LG in Germany and the United States, claiming the two companies infringed on Siemens’s patented LED lighting technology.
The technology transforms blue light into white light, a feature used in some flat-panel televisions and increasingly in common household LED light bulbs.
The German lawsuit was filed in Hamburg. In the United States, Siemens filed its complaints with the International Trade Commission in Washington and in United States District Court in Wilmington, Del. Siemens said it planned to file similar lawsuits against LG in Tokyo and China on Tuesday.
Siemens plans to sell a majority stake in the unit that owns the patents, Osram, the world’s No. 2 maker of lighting technology after Philips, in three months.
