Osram and Toyoda Gosei sign LED patent agreement

Oct. 30, 2007
Two major LED makers have agreed to share patented technologies related to blue LED chip fabrication, industrial production of LEDs and semiconductor lasers, and white LEDs.
Toyoda Gosei Ltd, a major LED maker based in Aichi, Japan, and Osram GmbH, a German LED maker, have signed an agreement for the mutual use of patents for certain LED and laser technologies.

Cooperation relates to indium gallium nitride (InGaN) semiconductor technologies that form the basis for laser diodes and LEDs in white, blue and green.

From Osram's side, this mainly involves basic technologies for the industrial production of LEDs and semiconductor lasers, and patents for white LEDs. Toyoda Gosei, which first developed blue nitride-based LEDs in 1991, possesses protected know-how relating to blue LEDs.

The companies say that the agreement will make it much easier for both of them to develop, manufacture and market new products without fear of unintentional patent violations. The two companies say that they are looking forward above all to considerable and speedy improvements in the luminous intensity of LEDs.

An Osram spokesperson confirmed to LEDs Magazine that the agreement does not include Lexedis Lighting, which is a joint venture between Toyoda Gosei and Tridonic Optoelectronics.

Ruediger Mueller, CEO of Osram Opto Semiconductors described the agreement as a prime example of respectful and responsible dealings with the intellectual property of other companies – with benefits for both the market and customers.

"Our cooperation with Toyoda Gosei, one of the world's most innovative LED manufacturers, will help make LED technology more available and will enable the infant market for LED products to develop in a spirit of fair competition," said Mueller.

Osram is proud of its forthright patent policy in the LED market, and says that it "relentlessly pursues" any infringements of its patent rights. At the same time, Osram has entered a large number of license agreements with other companies for the use of Osram patents and for the exchange of patents.
