Seoul
Semiconductor Co., Ltd. (KOSDAQ 046890) (“Seoul”), a leading global
innovator of LED products and technology, announced that it has filed a
patent infringement lawsuit in the United States District Court for the
Central District of California, against The Factory Depot Advantages
Inc., a distributor of Philips TV display.
In its complaint, Seoul asserts that a Philips LED TV display being sold
by this distributor infringe 10 (“ten”) patents regarding manufacturing
of LED backlighting unit. Particularly, these patented technologies
encompass LED TV backlight unit system for enhancing Color Gamut of LCD
displays, and LED lenses for providing uniform illumination on LCD
displays.
Seoul made significant R&D efforts since the beginning of the LED
backlight technology, and has established thousands of LED chip/package
patents, 150 of optical lens patents, and 200 of high color phosphor
application patents.
This is the 2nd litigation Seoul has filed a patent infringement lawsuit
against a Philips TV product distributor. In the past 2018, Seoul filed
a patent litigation for infringement of 19 patents against Fry’s
Electronics, a U.S. big box retailer that sold allegedly infringing TV
products. That litigation is also currently ongoing in the United States
District Court for the Eastern District of Texas.
“In order to protect our LED backlight system technology, we have
demanded a cease of infringement against global TV companies, TV ODM/
OEM manufacturers, and LCD display manufacturers operating in the US,
Europe and Asia,” said Sam Ryu, Seoul’s Vice President of IT Business.
“To establish fair market competition culture, wrong practice –
attempting unfair competition by using low-cost components that infringe
hard-earned patents – should be eliminated.”
