Recently, Seoul Semiconductor Co. Ltd enters into a cross license agreement concerning white LEDs using silicate system phosphors with TridonicAtco Optoelectronics GmbH (TOE) 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.
Based in Jennersdorf, Austria, TOE is part of the Zumtobel Group, the Austria-based lighting giant. Tridonic is an established supplier of chip-on-board LEDs and modules, and is a joint venture partner with Toyoda Gosei in Lexedis Lighting.
Phosphors are indispensable materials to manufacture white LEDs, especially those incorporating silicate system phosphors, are covered by a wide variety of patents and are significantly different from conventional LEDs using other phosphors. Based on this agreement, Seoul’s white LEDs using silicate system phosphors can be covered by its patents and such license and thus Seoul's customers will be able to enjoy using Seoul's white LEDs.
Under the cross license agreement, Seoul 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.
