Epistar, a leading innovator and manufacturer of LED solid-state lighting technologies, filed a patent infringement lawsuit against Adamax Inc.(d/b/a Newhouse Lighting) in the United States District Court for the Northern District of California on August 30, 2016. The complaint asserts that Newhouse Lighting products and technology infringe six Epistar patents and seeks injunctive relief to halt the further sale of the infringing Newhouse Lighting products.

Epistar’s complaint alleges that the Newhouse Lighting filament bulbs such as the Dimmable Flame Tip 3.5W LED Vintage Edison Filament Bulb infringe one or more claims of Epistar’s U.S. Patent Numbers 6,346,771, titled “High Power LED Lamp,” 7,489,068 titled “Light Emitting Device,” 7,560,738 titled “Light-Emitting Diode Array Having An Adhesive Layer,” 8,240,881 titled “Light-Emitting Device Package,”  8,791,467 titled “Light Emitting Diode And Method Of Making The Same,” and 9,065,022 titled “Light-Emitting Apparatus.”
