Lightside Continues Video Processing Campaign over Patents Issuing to “the Epitome of the Ingenious Tinkerer”

September 10, 2019

Lightside Technologies, LLC has followed up last month’s complaint against TCL Communication Technology (5:19-cv-01458) in the Central District of California with a new case this month against ZTE (3:19-cv-02128), filed in the Northern District of Texas. Each complaint asserts two different members of the same patent family, generally related to upscaling video content and providing video frame-rate conversion. Accused of infringement are TCL’s Roku HDTVs and UHDTVs and certain ZTE Axon smartphones with slow-motion video features. Previously, Lightside sued VIZIO (in 2017), Haier (in 2018), and Hisense (in 2019), each of which cases is now closed, the last administratively so to facilitate the finalization of a settlement.
