WASHINGTON, May 17 -- Nichia Corp. said that Kyoto-based Rohm Co. has filed a motion to withdraw its complaint against Nichia before the US International Trade Commission (ITC). The motion filed should conclude the related ITC investigation where it was alleged that certain Nichia parts infringed two US patents.
    "We believe the motion to withdraw removes any doubt that the ITC complaint was frivolous and that manufacturers in the US will have on-going access to Nichia's LEDs," said Noboru Tazaki, managing director and general manager of Nichia's Optoelectronics Products Division. "This turn of events also eliminates concern over the availability of violet and blue laser diodes in the US, as Nichia is the world's only commercial supplier of these parts."
