Epistar and Toyoda enter An LED cross license agreement

Epistar Corporation and Toyoda Gosei Co., Ltd. entered a cross license agreement to allow the companies (including subsidiaries)to use each other’s patents for specific technologies in Group III-V compound semiconductor light emitting diodes (“LEDs”), which include InGaN LEDs and AlGaInP LEDs.


Epistar is the only company in Taiwan, R.O.C. getting the cross license from Toyoda Gosei and no any other company in Taiwan gets any cross license from Toyoda Gosei until the date of this press released.

Epistar holds valuable patents for high-brightness AlGaInP LEDs and high-power GaN LEDs. Toyoda Gosei likewise holds a number of valuable patents for InGaN LEDs. Epistar and Toyoda Gosei agreed to construct an environment wherein they will respect and mutually utilize each other’s technologies in order to further advance the market for LED products.

This agreement will allow both Epistar and Toyoda Gosei significantly more freedom in their development efforts by eliminating the need for concern about each other’s patents. By facilitating research at both companies, new developments in LED technology are anticipated, including an acceleration of research to improve the luminosity of LEDs. Epistar and Toyoda Gosei each intend to maintain a friendly business relationship and pursue the development of superior high-luminosity LEDs and further expansion of the LED market through fair competition.
