Tridonic Reaches Settlement with AOC International on Silicate-based White LED Patent Lawsuit

Tridonic Jennersdorf GmbH, a subsidiary of Tridonic GmbH & Co KG, Dornbirn and part of the Zumtobel Group, has entered into a settlement agreement with the AOC International (Europe) B.V. and AOC International (Europe) GmbH for the use of silicate-based white LEDs.

Tridonic Jennersdorf GmbH holds together with Toyoda Gosei Co., Ltd from Japan and Leuchtstoffwerk Breitungen GmbH and Litec GbR from Germany (the four members of the B.O.S.E. consortium) basic patents for a technology to generate white light using blue LEDs and yellow silicate phosphors.

AOC fully respects and recognizes the patents and patent applications held by B.O.S.E. consortium, in particular the European Patent EP 1 352 431 B1.

The silicate-based white LED technology enables white LEDs to be produced with higher accuracy and increased brightness; preferred applications for these kinds of LEDs are smartphones, notebooks, navigation systems, and other display products, and the technology is thus relevant for a significant proportion of today’s LED market. To provide this white light LED technology to the LED industry, the B.O.S.E. consortium offers two different licensing models: an application license for the use of the white light LED technology and a material license for the production and sale of the relevant luminescent materials.

The B.O.S.E. consortium has already granted an application license for its white light LED technology to over 40 LED manufacturers worldwide.
