Epistar files US patent infringement lawsuit against Lowe’s

On 28 April, LED epitaxial wafer and chip maker Epistar Corp of Hsinchu Science-based Industrial Park, Taiwan filed a lawsuit in the US District Court for the Central District of California against Lowe’s Companies Inc and Lowe’s Home Centers LLC.

The complaint alleges that the Kichler Lighting’s LED filament bulbs sold by Lowe’s - such as the Kichler Lighting 60W Equivalent Dimmable Soft White A15 LED Decorative Light Bulb (P/N: YGA16A08-A15C-CL-5W) - infringe one or more claims of Epistar’s US patent numbers 6,346,771 ‘High Power LED Lamp’, 7,560,738 ‘Light-Emitting Diode Array Having An Adhesive Layer’, 8,791,467 ‘Light Emitting Diode And Method Of Making The Same’, 8,492,780 ‘Light-Emitting Device And Manufacturing Method Thereof’, and 8,587,020 ‘LED Lamp’.

The complaint also alleges that Utilitech’s LED bulbs sold by Lowe’s - such as the Utilitech 60W Equivalent Warm White A19 LED Light Fixture Light Bulb (P/N: YGA03A41-A19-9W-830) - infringe one or more claims of Epistar’s US patent numbers 8,492,780 ‘Light-Emitting Device And Manufacturing Method Thereof’ and 8,587,020 ‘LED Lamp’.

The lawsuit seeks injunctive relief to halt further sale of the infringing products.

Epistar says that it has invested millions of dollars in R&D on LED technologies that have led to a portfolio consisting of over 4000 issued patents and pending patent applications, laying the foundation of its LED filament (bulb) and/or LED bulb technologies.
