SETi gains permanent injunction against Bolb and Quantum Egg

Sensor Electronics Technology Inc (SETi) of Columbia, SC, USA – a division of South Korean LED maker Seoul Semiconductor and UV LED product maker Seoul Viosys Co Ltd (SVC) that manufactures UV-A, UV-B and UV-C deep-ultraviolet LEDs (emitting at wavelengths shorter than 340nm) – has obtained a permanent injunction in a patent infringement lawsuit against US-based Bolb Inc 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 colorable variations. 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 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.

After expanding into 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 to $1.2bn in 2022, according to a report last year by LEDinside.

SETi has also collaborated with Seoul Viosys, 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 the USA’s largest heating and cooling manufacturing brand. This product has been recognized by customers for its high performance in sterilizing various bacteria that live inside air-conditioning equipment and preventing it from spreading inside a home office during operation.

“It is difficult to survive on a long-term basis in the UV LED industry without a strong foundation in intellectual property and technology expertise, something that SETi and SVC have gained thanks to their extensive investment in research and development,” says SETi’s CEO Chae Hon Kim.

“SETi believes in furthering a market of fair competition and investment in intellectual property. We believe that this rewards research and development, allowing entrepreneurs and small businesses to have their hard work recognized in the marketplace,” he adds.

“As a UV LED pioneer developing commercialized UV LED for the first time in the world, we plan to make our products available at even more competitive pricing to encourage the distribution of our green technology products in the market,” Kim concludes.
