Japanese IP High Court Issues Decision Regarding Universal Display’s Early Phosphorescent Patent

Universal Display Corporation announced that the Japanese IP High Court delivered a decision reversing the Japanese Patent Office’s (JPO) prior invalidation of the broad claims in the company’s Japanese Patent No. JP-4511024 (the JP ‘024 patent). The matter was remanded back to the JPO for further consideration consistent with the IP High Court’s ruling.

The JPO’s prior decision, on May 10, 2012, confirmed the novelty of Universal Display’s basic invention in JP ‘024, but invalidated the broad claims. This was in response to Semiconductor Energy Laboratory Co., Ltd.’s (SEL) June 2011 request for a complete invalidation of JP ‘024. With the belief that the JPO’s decision regarding the broad claims was erroneous, Universal Display appealed the decision to the Japanese IP High Court.

“We are pleased that the Japanese IP High Court recognized the novelty of our phosphorescent patent and confirmed our belief in the validity of JP ‘024’s broad claims,” said Steven V. Abramson, president and CEO of Universal Display
.
JP ‘024 is one of more than 60 patents issued worldwide that cover four early fundamental phosphorescent OLED inventions developed at Princeton University and the University of Southern California, which are exclusively licensed to Universal Display Corporation. Universal Display’s basic phosphorescent patents encompass organic light emitting devices that produce electroluminescence using an emissive layer comprised of a phosphorescent material.
