On September 19, South Korea's LED professional company Seoul Semiconductor and its subsidiaries said that the US LED lighting company, which infringes on subsidiary Acrich technology and sells its products, has filed a patent infringement lawsuit in the federal court in California.
Seoul Semiconductor said in a complaint that several LED lights, including filament LED lamps, sold by Archipelago Lighting, Inc., infringe on 12 related patents of Seoul Semiconductor. The infringed Seoul Semiconductor Acrich patents include high-voltage drive LED drive technology, multi-chip manufacturing and multi-junction technology (MJT), LED packaging, filament LED manufacturing technology, LED epitaxial growth and chip manufacturing technology, all of which manufacture and drive LEDs. The necessary core technology.
According to the data, conventional LEDs typically drive an LED (device) at a high current at a low voltage of 3V. Therefore, in order to increase the brightness of the illumination, it is necessary to configure a plurality of components and connect the components to each other (wiring). Therefore, the size of the drive circuit is increased, the price is increased, and the possibility of malfunction due to wiring is also high.

However, with the optimization of LED driver technology, Acrich can integrate multiple LED chips into a small-area high-voltage operation and multi-chip mounting technology (MJT), which can simultaneously obtain high voltage and output with a small number of LEDs. Since it is directly driven directly from the AC without a converter, the overall efficiency of the product (Wall-plug Efficiency) is high, because power conversion process is not required, so the power loss in the circuit can be minimized. Moreover, as the number of LEDs used is reduced, space utilization is increased, which simplifies circuit design and reduces the size and cost of illumination.
The director of the Seoul Semiconductor Research Institute said, "At present, extensive investigations have been conducted on LED TVs, general lighting and automotive lighting products using the Acrich technology.", "Acrich technology developed to protect Seoul Semiconductor for decades." For companies that ignore patent infringement warnings and continue to use infringements, they will actively respond and file patent litigation. This will enable young people and SMEs to see hope."
Gaogong LED has learned that this is not the first patent infringement lawsuit initiated by Seoul Semiconductor in 2017. As early as April 13, Seoul Semiconductor official website issued a statement that the global electronic components distributor Mouser Electronics infringed on its high-power LED related patents, has filed a lawsuit in the German District Court of Düsseldorf.
According to Seoul Semiconductor related sources, the patent infringement products are high-power LEDs produced by Everlight Electronics and most LED manufacturers, the world's top ten LED manufacturers. Mouser has sold and distributed LED products manufactured by these companies. Object.
Seoul Semiconductor has a large patent network with a high patented technology. In its lawsuit against patents, it has won the lawsuit. In June of this year, Seoul Semiconductor won a patent lawsuit against Kmart of 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.
It is understood that Seoul Semiconductor is a professional semiconductor manufacturer in Korea. It has more than 10,000 patents in the semiconductor field. Its self-developed unpackaged LED, multi-structure chip, DC AC can drive Acrich, UV sterilization and so on. Innovative technology leads the development of the global LED field. Since winning the patent lawsuit against Taiwan in China in 2003, Seoul Semiconductor has initiated more than 50 patent wars in the United States, Europe, Japan, South Korea and other places, and all ended in victory.
