Polaris PowerLED Hits Samsung Again as Judge Gilstrap Clears the Way for Trial Between the Two

June 15, 2019

On the eve of its trial in the Eastern District of Texas in a case filed against Samsung in October 2017, Polaris PowerLED Technologies, LLC has filed a second suit against the company (2:19-cv-00229) in the same district. District Judge Rodney Gilstrap held a final conference on June 11, 2019 in preparation for trial over a single patent generally directed to setting the brightness level of an electronic display based on the ambient light level, targeting certain Galaxy smartphones and tablets as well as other products. The new complaint asserts a different patent, generally related to controlling a “backlight system”, accusing Samsung of infringement through the provision of certain televisions, particularly calling out “a local dimming feature that dims the backlight behind parts of the screen that are displaying black”. That patent is already at issue in the campaign, having been asserted in a September 2018 suit against VIZIO in the Central District of California.
