Taiwan-based LED epitaxial wafer and chip manufacturer Epistar Corp has filed a patent infringement lawsuit against V-TAC USA Corp in the United States District Court for the Central District of California. The complaint asserts that V-TAC’s LED filament bulbs infringe seven Epistar patents and seeks injunctive relief to halt further sale of the infringing products.
Epistar’s complaint alleges that the V-TAC’s LED filament bulbs such as the VT-5115D Light Bulbs (P/N: 215), VT-5100D Light Bulbs (P/N: 200) and VT-5133 Light Bulbs (P/N: 283) infringe one or more claims of Epistar’s US patent numbers 6,346,771 (‘High Power LED Lamp’), 7,489,068 (‘Light Emitting Device’), 7,560,738 (‘Light-Emitting Diode Array Having An Adhesive Layer’), 8,240,881 (‘Light Emitting Device Package’), 9,065,022 (‘Light Emitting Apparatus’), 9,488,321 (‘Illumination Device With Inclined Light Emitting Element Disposed On A Transparent Substrate’), and 9,664,340 (‘Light Emitting Device’).
