Seoul Semiconductor files patent lawsuit against second Philips TV display distributor

South Korean LED maker Seoul Semiconductor Co Ltd 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 displays.

Seoul asserts that a Philips LED TV display being sold by this distributor infringes 10 patents regarding manufacturing of LED backlighting units. In particular, the patented technologies encompass an LED TV backlight unit system for enhancing the color gamut of LCD displays, and LED lenses for providing uniform illumination to LCD displays.

Seoul says that it has made significant R&D efforts since the beginning of the LED backlight technology, and has established thousands of LED chip/package patents, 150 optical lens patents, and 200 high-color phosphor application patents.

This is the second patent infringement lawsuit that Seoul has filed against a Philips TV product distributor, after filing a lawsuit last year for infringement of 19 patents against Fry’s Electronics (a US big-box retailer that sold allegedly infringing TV products). That litigation is also currently ongoing in the US District Court for the Eastern District of Texas.

“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,” says Sam Ryu, Seoul’s VP 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.”
