Seoul Semiconductor Files Filament LED Patent Lawsuit against Feit Electric’s Distributor

Seoul Semiconductor has filed a patent infringement lawsuit in the United States District Court for the Western District of Texas against Ace Hardware, a global retail company, for selling filament LED bulbs and other LED products manufactured by Feit Electric.

Seoul claims that the infringement is willful and that Ace Hardware has continued to sell Feit Electric’s products despite repeated notices.
 
Seoul asserts infringement of 16 LED patents covering the manufacturing of LED epitaxy, chips, packages, modules, lenses, and drivers. Those second generation LED technologies include technologies for high color rendering, LED driver for high-voltage operation, LED multi-junction, light diffusion lens, light extraction, and LED reliability. Such technology is the result of more than USD 1 billion of R&D investment.
