Seoul Semiconductor 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, a distributor of Philips TV display.

In its complaint, Seoul asserts that a Philips LED TV display being sold by this distributor infringe 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.

This is the 2nd litigation Seoul has filed a patent infringement lawsuit against a Philips TV product distributor. In 2018, Seoul has accused Fry’s Electronics, a U.S. big box retailer, of selling TV products that infringe 19 patents of Seoul. 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.”
