Dow Corning, a global leader in silicones, silicon-based technology and innovation, announced that the European Patent Office (EPO) rejected a request to revoke patent EP-1556443. The patent is part of the rich intellectual property (IP) portfolio that protects the company’s proprietary high refractive index (RI) phenyl-silicone-based optical encapsulant technology, which offers enhanced light output, improved reliability and other benefits for high-brightness LED lighting designs.  The EPO’s decision significantly strengthens Dow Corning’s IP position in Europe’s fast-growing LED lighting market where patent compliance is strategically important, as well as other key global LED manufacturing centers, such as the U.S., Japan, Korea and China.

Haydale, the group focused on the commercialisation of graphene and other nano particle products using its proprietary plasma process, is pleased to announce confirmation from the European Patent Office (“EPO”) of the decision to grant a European Patent to Haydale (“European Patent”).
