Seoul Semi wins LED backlight lawsuit

March 28, 2016 // By Peter Clarke
LED manufacturer Seoul Semiconductor Co. Ltd. (Seoul, South Korea) has won a patent infringement lawsuit regarding LED backlight lens technology against Japanese lens maker Enplas Display Device Corp.

The companies have been involved in a series of lawsuits that date back to October 2013. On March 24, 2016 a federal jury in North District of California decided that Enplas actively induced infringement of Seoul’s patented technology with respect to all of the asserted patent claims and that such infringement was willful. The jury ruled that Seoul’s LED TV backlight lens patents are valid and rejected Enplas’s invalidity arguments. The jury awarded Seoul $4.07 million in damages for inducement.

Where infringement is willful it is often the case that the court will award triple the initial sum set by the jury and so Seoul could receive $12 million.
