Korean Tribunal Upholds Critical Dow Corning Patent for Industry-Leading LED Optical Silicone Encapsulants

Published Sep 24, 2013

SEOUL, South Korea – Signaling the end of a patent battle lasting for almost three years, Korea’s Intellectual Property Tribunal (IPT) rejected an attempt to invalidate Dow Corning’s patent 10-976075. The patent is among Dow Corning’s rich intellectual property (IP) portfolio covering the company’s proprietary high refractive index (RI) phenyl-based optical silicone technology, which offers numerous high-value benefits to LED devices. These benefits include improved light output, excellent mechanical protection of LED components and enduring gas barrier properties for enhanced reliability. Handed down by the IPT on August 9, the decision in favor of Dow Corning significantly strengthens its intellectual property position for the technology in Korea, as well as in other key global LED manufacturing centers, including the U.S., Japan, Taiwan, China, Malaysia and Europe.
