Seoul Semiconductor Continues Enforcement against Infringement of Its LED Driver Patents
ANSAN, South Korea–(BUSINESS WIRE)– Seoul Semiconductor Co., Ltd. (KOSDAQ 046890) (“Seoul”), a leading global innovator of LED products and technology, announced that it has filed another patent infringement lawsuit for infringement of its LED driver patents, this time against SATCO Products, Inc. (“SATCO”).
In its complaint, Seoul asserts that SATCO is selling various LED lighting products that infringe “eleven” (11) of Seoul’s patents covering LED driver technology, including U.S. Patent 7,081,722, U.S. Patent 9,807,828; U.S. Patent 8,513,899; and U.S. Patent 8,716,946.
The asserted LED driver patents are widely used in replacement bulbs in the form of incandescent or fluorescent lamps, wall-mount lights, and ceiling lights. The patented technology covers products with a linear driver for directly operating LEDs under household voltage, a step operation driver for generating flicker-free lights, as well as a dimmable driver for realizing smart lighting.
Seoul has successfully enforced its LED driver patents in several prior litigations spanning the different parts of the market, including big box retailer, LED lighting maker, and application maker segments of the market.
Seoul’s Acrich NanoDriver Series devices, made with this patented technology, was named as a winner in the Sapphire Award category “ICs & Electronic Components for Solid State Lighting.” By virtue of its continuous technology innovations, Seoul owns over 250 patents concerning LED driver technology around the world.
Acrich driver technology applies to an estimated 70% of residential light bulbs throughout the global lighting market, and Seoul estimates that Acrich’s applications will continue to expand.
“Seoul has invested an approximately 10 percent of its sales revenue each year to innovate technology. Last year, we invested even more to ensure that we are at the cutting edge of technology,” said Nam Ki-bum, Executive Vice President of the Lighting Department at Seoul. “But unfair competition by copying innovative products must stop. Only then will others, including young entrepreneurs and small businesses, have a chance to have their talents recognized in the market.”
