Sensor Electronic Technology Obtains Permanent Injunction against U.S. UV LED Companies

Sensor Electronic Technology obtained a permanent injunction in a patent infringement lawsuit against Bolb, Inc. (“Bolb”), and Quantum Egg, Inc. (“Q-Egg”).

The California Northern District federal court issued a permanent injunction against the sales of an accused UV LED sterilizer device, as well as any mere colorable variations, according to the parties’ stipulation. The Court will therefore prohibit the sale of similar products if they prove to be mere colorable variations of the accused products.

The asserted patents in this litigation cover fundamental UV LED technology, encompassing UV LED sterilizer structures and drivers, chip fabrication, and epitaxial layer growth.

Bolb is a UV LED company co-founded by former SETi employees, and Q-Egg was the distributor of the accused UV LED sterilizer device.

The UV LED market has expanded to a range of fields, including air and water purification devices, as well as medical and bio devices for skin care. The UV LED market value will grow up to $1.2 billion in 2022 according to a market report from LEDinside (2018).

SETi has also collaborated with South Korean UV LED company Seoul Viosys Co., Ltd. (“SVC”), resulting in the development of Violeds technology for UV LED-based disinfection, deodorization, phototherapy and curing. Violeds technology has been used by the US National Aeronautics and Space Administration (NASA) aboard the International Space Station (ISS). SETi also supplies UV LED products to America’s largest heating and cooling manufacturing brand company. This product has been recognized by customers for its high performance in sterilizing various bacteria that live inside air conditioner equipment and preventing it from spreading inside a home or office during operation.
