In the patent infringement lawsuit against LED bulb products, Seoul Semiconductor won the victory of Kmart in the United States. With the victory of this patent litigation, it issued a patent infringement warning letter to LED lighting manufacturers to create a good social environment that respects intellectual property rights. Bring hope to the younger generation.
Seoul Semiconductor, Korea's first LED professional manufacturer, won a patent lawsuit against Kmart in the United States. Kmart is a large global retailer with a 120-year history and annual sales of 30 trillion won (about US$26 billion). Due to the infringement of Seoul Semiconductor's LED patents, it decided to accept Seoul Semiconductor's request to discontinue sales of related products.
Seoul Semiconductor said that LED bulbs sold by Kmart infringe on our company's LED bulb manufacturing including high color rendering technology, phosphor combination technology, multi-chip placement technology, LED epitaxial layer growth and chip manufacturing technology, and Omni direction LED bulb technology. The necessary patents, so in September last year, targeting Kmart, Seoul Semiconductor filed a patent infringement lawsuit in the federal court in California. At that time, the infringement patents claimed by Seoul Semiconductor also included the original patent related to the filament LED invented by Seoul Semiconductor Technical Consultant and the Nobel Prize in Physics 2014.
Regarding whether or not patent infringement, the two sides launched a fierce offensive and defensive war. Finally, Kmart reached an agreement with Seoul Semiconductor to respect Seoul Semiconductor patents and stop selling LED bulbs. Seoul Semiconductor won a patent lawsuit against Kmart, a large US retailer. This is not only the first victory that Seoul Semiconductor has won as a patent litigation by global retailers, but also the fact that it has relevant original technology in the manufacture of LED bulbs. Not only is global retailer Kmart, Seoul Semiconductor recently filed a second patent lawsuit against Germany's global electronic component distributor Mouser in Germany.
In addition, Seoul Semiconductor recently issued a warning letter to large LED bulb manufacturers including LED filament lamp manufacturers to stop manufacturing patent infringing products. At present, filament LED bulbs are manufactured by Supretrend, Longstar, Topstar, Yankon and many other lighting manufacturers. If patent infringement continues to exist, Seoul Semiconductor will consider filing an additional lawsuit.
The reason for issuing a warning letter to LED manufacturing companies is that products that infringe Seoul Semiconductor's LED patents are circulating in the market. Since the beginning of 2000, Seoul Semiconductor has been developing LED bulb products, and has related patents including LED bulb manufacturing core technology - chip manufacturing, transparent COB packaging, modules, and bulb manufacturing processes.
Mr. Nam Ki-bum, vice president of Seoul Semiconductor Research Center, said that many LED bulbs circulating in the market are infringing on Seoul Semiconductor patents, so Seoul Semiconductor will take more active measures to control patents from the end of the Kmart lawsuit. Infringement. He added that we should work hard to eradicate the spread of patent infringements in the industry, so that retailers also respect intellectual property rights and no longer sell infringing products. For those who continue to correct patent infringement despite repeated warnings, Seoul Semiconductor will continue to file patent infringement lawsuits against infringing manufacturers and their retailers.
