TWH104-HS), which Seoul Semiconductor produces and sells, infringe on Nichia's Korean patent (no. 406201). Nichia seeks damages for past infringement as well as an injunction against any further infringing activity.

In addition, Seoul Semiconductor has entered cross-licensing and strategic cooperation agreements with leading LED-chip producers including Cree Inc. in the US, OSRAM GmbH in Germany and Toyoda Gosei in Japan.

Seoul Semiconductor also announced its strong response to a lawsuit filed by Nichia Corporate against the company in Seoul Central District Court today.
