Seoul Semiconductor Expands Patent Infringement Litigation Against LED TV Distributor

News
Seoul Semiconductor, has expanded its patent infringement litigation against Fry’s Electronics, Inc., a big-box consumer electronics retailer, in the United States District Court for the Eastern District of Texas. Seoul asserts that top brand televisions being sold in Fry’s stores infringe 19 patents covering backlight lenses, backlight modules, LED chips, LED packages, and phosphors, as well as Seoul's WICOP technology.

In its amended complaint, Seoul asserts that top brand televisions being sold in Fry's stores infringe 19 patents covering backlight lenses, backlight modules, LED chips, LED packages, and phosphors, as well as WICOP technology that enables LED chips to be directly soldered onto printed circuit boards (PCB). Seoul's patent infringement lawsuit against Fry's was originally filed on August 31, 2018.

Seoul's backlight lens patents relate to a new concept of lens technology for manufacturing thin and light televisions. This patented technology was developed jointly with leading optical expert, Dr. David Pelka, and included substantial research and development investments by Seoul in optical lenses. As a result of these investments, Seoul has approximately 160 related patents in this area.

Seoul's backlight module patent enables significant improvement of the colour gamut of LCD displays by using KSF phosphors. The related technology has been co-developed with Mitsubishi Chemical Corporation for many years and has been widely incorporated in most mobile phones and increasingly applied in LCD TVs as well.

Seoul's WICOP (Wafer Incorporated Chip on PCB) patents enable LED chips to be soldered to a PCB without an LED package - described as one of the world's first developed revolutionary technologies for semiconductor structures. Other companies may be attempting to imitate Seoul's patented technology, describing it as a CSP (Chip Size Package) requiring a sub-mount between a PCB and an LED. Protecting its patented technology has led Seoul to expand its infringement claims in the Fry's ligation.

In order to safeguard its LED backlight technology and other protected inventions, Seoul has actively enforced its patent rights and sent cease-and-desist letters against suspected infringers. As a result of such enforcement efforts, the United States Federal Circuit Court of Appeals issued a decision on November 19, 2018 that one of Seoul's competitors willfully infringed Seoul's LED lens and backlight module patents. The appellate court also found that that Korean LED package company Lumens Co., Ltd supplied television makers with LED backlight bars incorporating infringing products.

“We hope that our commitment for technology innovation would inspire young entrepreneurs and small businesses,” said Sam Ryu, Seoul's vice president of IT Business. “Protecting that technology against infringement is a cornerstone of our business and sends an important message to the market and other innovators who would follow in Seoul's footsteps - that hard work and innovation will be respected.”




CS International 26-27 March 2019, Sheraton Airport Hotel, Brussels

In its ninth year, CS International will continue to provide timely, comprehensive coverage of every important sector within the compound semiconductor industry. Presentations are split into 5 key themes and each industry key theme will be delivered by a keynote presentation from a leading industry figure as well as a market analyst presentation tailored to the theme. Together, the talks will detail breakthroughs in device technology; offer insights into the current status and the evolution of compound semiconductor devices; and provide details of advances in tools and processes that will help to drive up fab yields and throughputs. Attendees at the two-day conference will gain an up-to-date overview of the status of the CS industry, and have opportunities to meet many other key players within this community.
