Dec 21, 2016: Seoul Semiconductor, a leading Korean LED maker, has taken legal action against 29 companies in US, China, Europe and Taiwan, for infringing its backlight, filament, LED chip and package patents, according to a Business Korea report.
In fact, Seoul Semiconductor sent its engineers and intellectual property law team and lawyers to these companies. The team urged them to respect Seoul Semiconductor’s intellectual property rights for its patents they infringed on.
These 29 companies named in the patent infringement suit include seven US firms, including Feit Electric; three European firms including LEDVANCE and Redvan; 15 Chinese firms including Skyworth; and four Taiwanese companies including AOT.
The LED TVs, smartphone flash and LED filament light bulbs of these companies violated Seoul Semiconductor’s patents for technologies used in smartphones, TVs, and lighting. For example, the Wafer Level Integrated Chip on PCB (Wicop), which is the world’s first technology to free from packaging process for conventional LED package manufacturing. The Acrich Multi-Junction Technology (MJT), works on high voltage power for domestic use. The Filament is a new design technology for lamps.
Seoul Semiconductor has also issued a cease and desist order to Japanese LED lens manufacturer Enplas. Since 2013, the company is been involved in a global litigation with Enplas on backlight lenses patents. The US district court upheld a finding that Enplas has infringed Seoul Semiconductor’s patented technology and is liable for US$4 million (4.74 billion won) penalty.
