(openPR) - Seoul enters into a cross license agreement with TOE (TridonicAtco Gmbh) of Europe and its patent partners
- Based on this cross license agreement, Seoul enhances its flexibility to manufacture various kinds of LEDs besides its own white LEDs

Seoul Semiconductor Co., Ltd. ("SSC") today announced that SSC has entered into a Cross License Agreement regarding white LEDs using silicate system phosphors with TridonicAtco Optoelectronics GmbH ("TOE") and its patent partners. Phosphors are indispensable materials to manufacture white LEDs. Especially, white LEDs incorporating silicate system phosphors are covered by a wide variety of patents and are significantly different from conventional LEDs using other phosphors. Under the Cross License Agreement, SSC is in a very strong position to manufacture and sell its own white LEDs using silicate system phosphors as well as expand and accelerate relevant R&D activities.
Based on this agreement, SSC's white LEDs using silicate system phosphors can be covered by its patents and such license and thus SSC's customers will be able to enjoy using SSC's white LEDs.
