Decision rendered by the Japan Patent Office

Everlight Electronics Co. Ltd.
filed an invalidation action with the Japan Patent Office against Nichia Corporation’s YAG white light LED patent (patent No. JP3503139). Everlight has received the decision from the Japan Patent Office recently.

The Japan Patent Office rendered a decision on May 8th, 2012, holding that the patent JP3503139 is invalid. The ruling includes the invalidation of Claim 1, which is the main claim of the patent at issue.

Everlight believes that this decision is entirely reasonable.
