Patent Infringement Litigation on Phosphorescent Pigments Concluded
Nemoto & Co., Ltd., Tokyo, inventor and owner of worldwide patents for long-afterglow and super-bright phosphorescent (photoluminescent) pigments based on strontium aluminate, has marketed its patented products worldwide since 1995.
UMC, Lyndhurst, N.J., is the sole distributor and the licensee of the Nemoto-patented products in the NAFTA region. The patented products are sold under the LumiNova® brand.
Nemoto and UMC will continue to pursue infringers selling non-licensed pigments in order to prohibit the installation of inferior materials in buildings, aircraft, trains and subways, and other public facilities requiring photoluminescent products used in egress systems for public safety. Nemoto and UMC demand that infringers compensate them for infringing sales and destroy existing inventories as the basis for settling litigation.
