Osram GmbH, one of the leading lighting companies, has granted Taiwan’s Unity Opto Technology Co. Ltd. a royalty-bearing license to produce white LED packages under Osram core patents covering phosphor conversion technology. This technology is widely used in the LED industry for the generation of white light based on a semiconductor chip emitting blue light that is partially converted into one or more other colors by suitable phosphor materials.

The agreement with Unity Opto follows numerous license agreements between Osram and other producers of white LED packages. In total, more than 20 globally active LED producers are licensed under Osram’s core LED patents.

Osram and Unity Opto have also agreed to dismiss the pending patent litigation Osram had brought against Unity Opto’s customer ASUS in Germany. The District Court in Düsseldorf had awarded Osram an injunction and found that ASUS had to compensate Osram’s damage caused by the patent infringement.

Dieter Boss, Osram Head of Licensing said: “Osram has built up a very strong patent position. We welcome Unity Opto as a licensee under our White LED License Program. To LED producers not licensed by Osram but still making use of our patents, we would like to send the message that Osram will continue to vigorously enforce its patents.”
