Seoul Semiconductor wins permanent injunction in US against operator of 1000bulbs.com

South Korean LED maker Seoul Semiconductor Co Ltd has won a patent infringement lawsuit against Service Lighting And Electrical Supplies Inc, an operator of 1000bulbs.com (the largest online light bulb distribution channel).

The Texas Northern District federal court issued a permanent injunction against the sales of more than 50 lighting products, as well as any colorable variations of those products unless they have been licensed, 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, says Seoul Semiconductor.

In the litigation, Seoul Semiconductor asserted 10 patented technologies significant for LED bulb components, such as a Multi-Wavelength Insulation Reflector widely used for ‘0.5W to 3W’-level mid-power LED packages, Multi Junction Technology for mounting and integrating many LEDs within a small area, LED Driver technology for current conversion and control, and LED packages with enhanced durability. In particular, Multi Junction Technology is essential for manufacturing 12V/18V high-voltage lighting products, and Seoul is the pioneer of this technology.

Recently, the German court also issued two permanent injunction judgments against the sale of products infringing Seoul’s patents and also ordered the distributor to recall such products in December 2018 and August 2019, respectively.

“We hope that Seoul’s success story based on significant R&D efforts could show a good example to young entrepreneurs and small businesses struggling to have their talents recognized in the market,” comments Seoul’s founder Chung Hoon Lee. “We will continue necessary actions against companies that we suspect of infringing our patents of unlawful access to our trade secrets by luring employees,” he adds.
