Epistar Granted Exclusive License to UCSB Filament LED Patent

Epistar Exclusively Licenses UCSB Patent

Epistar reports that now it has acquired additional patents to enhance its IP portfolio including an exclusive license obtained from University of California, Santa Barbara, UCSB, U.S. for Patent No. 7,687,813 (the 813 patent) invented by Dr. Shuji Nakamura and Dr. Steven P. DenBaars titled “Standing Transparent Mirrorless Light Emitting Diode.”

The (813 patent) describes an LED from which multi-directional light can be obtained from one or more of the LED’s surfaces before entering an inverted cone-shaped optic. Subsequently, the light from the LED is emitted in multiple directions through the air. Also, this arrangement stands the LED on end, thereby rotating the position of the LED within the shaped optical element by about 90 degrees. Like the previously mentioned LED patents, this latest one relates to a possible configuration of a filament LED.

It has been more than 20 years since the founding of Epistar in 1996. The company says that since its founding in 1996, it has focused on research and development of innovative LED solutions, and has taken steps to protect its intellectual property. To date, Epistar boasts over 4000 patents and patent applications.

Epistar Focused Filament LED Bulbs

In a somewhat unusual move, Epistar has focused its research and development on LED filament bulbs. According to the company, these efforts lead to several pioneering patents including, but not limited to, U.S. Patent No. 9,065,022 titled, “Light Emitting Apparatus” that cover filament bulb technologies, U.S. Patent No. 8,240,881 entitled “Light-Emitting Device Package.”

The U.S. patent office has also awarded the company U.S. Patent No. 8,791,467 entitled “Light Emitting Diode And Method Of Making The Same” that cover filament technologies, U.S. Patent No. 7,560,738 and titled, “Light-Emitting Diode Array Having An Adhesive Layer,” U.S. Patent No. 7,489,068 titled, “Light Emitting Device,” and U.S. Patent No. 6,346,771 titled, “High Power LED Lamp,” that cover filament bulb technologies.

Super Trend Lighting and Q L Light Source have obtained licenses to all of the Epistar patents identified above.
