TOKYO, Japan - On July 7, 2008, Nichia Corporation ("Nichia") filed a patent infringement lawsuit in Germany against a Korean company, Seoul Semiconductor Co. Ltd. ("Seoul Semiconductor"), a German subsidiary of Seoul Semiconductor, Seoul Semiconductor Europe GmbH, and its German distributor, Conrad Electronic SE seeking injunctive relief and compensation for damages.

The subject of this lawsuit, seeking an injunction and recovery of damages, is against the Acriche Series White LED product manufactured by Seoul Semiconductor, which Nichia believes infringes their patent [EP(DE)622858]. As one of the main products of Seoul Semiconductor, these Acriche products are also being used for streetlights in Europe.

In order to protect its intellectual properties, Nichia has also filed lawsuits in the U.S., Japan, Korea and the U.K against Seoul Semiconductor and its Japanese and U.S. subsidiaries for injunctive relief and compensation for damages, which are all currently pending:

• The U.S. lawsuit for design patent infringement of side-view white LEDs (The jury affirmed Seoul Semiconductor's willful infringement of Nichia design patents)

• The 1st Japanese lawsuit for patent infringement of white power LEDs and the 2nd Japanese lawsuit for patent infringement of chip-type white LEDs.

• The 1st Korean lawsuit for patent infringement of chip-type white LEDs and the 2nd Korean lawsuit for patent infringement of white power LEDs.

• The U.K. lawsuit for patent infringement of Acriche Series White LEDs.

About Nichia Corporation

Having "Ever Researching for a Brighter World" as our motto, Nichia has grown in the field of manufacturing and sales of fine chemicals, particularly inorganic luminescent materials (phosphors). In the process of the challenging pursuit of brighter luminescent and light-emitting materials, we succeeded in developing and commercializing the super high brightness Blue LED in 1993. It was accepted with great amazement in the related industries throughout the world. Since the first announcement of the Blue LED in 1993, Nitride-based LEDs in different emission colors ranging from Ultraviolet to Yellow have been contributing to the diversification of LED application fields. In addition to LEDs, a lot of resources are now being focused on the R/D of bluish purple laser diodes, which will definitely play a key role for the further expansion of the information media industry. We have a belief that Nitride-based semiconductors will become one of the most exciting areas of the semiconductor industry in the near future. We hope that Nichia continue to be a company which will be able to make a contribution to the world by evolving its original and unique technologies into the actual manufacturing.
