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 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.
