Multimodal Media LLC has expanded its sole litigation campaign, launched with suits against OPPO and ZTE in November 2021. The subsidiary of publicly traded Quest Patent Research Corporation (QPRC) has now sued Samsung (2:22-cv-00462) and TCL (2:22-cv-00463) in separate Eastern District of Texas cases. The four asserted patents—originally developed at Kirusa, a telecommunications company founded in 2001 by “a handful of technocrats from AT&T Bell Labs”—are broadly directed to various mobile communications technologies. The defendants are accused of infringement through the provision of smartphones and tablets that support certain calling and messaging capabilities.
