These two patents are directed to YAG phosphor being used in LEDs and phosphor concentration. The court confirmed that all asserted claims of Nichia’s patents were invalid. Aside from the U.S. court ruling, Everlight has receive favorable rulings in Japan and Taiwan that Nichia’s patents are invalid.

(“Mouser”), Everlight clarified that the company has signed patent cross license agreement with Osram since 2003. Osram later extended the license for white and colored LEDs with Everlight in 2009.
