Multimodal Media LLC, a subsidiary of publicly traded Quest Patent Research Corporation (QPRC), has filed its first litigation, suing BBK Electronics (OPPO) (2:21-cv-00436) and ZTE (2:21-cv-00437) over the provision of smartphones and tablets that support certain calling and messaging capabilities. The four asserted patents were developed by Kirusa—a telecommunications company founded in 2001 by “a handful of technocrats from AT&T Bell Labs”—and were acquired as part of a nine-patent portfolio for which QPRC reports that it paid $550K. In October, a different QPRC subsidiary hit both OPPO and ZTE, alleging infringement of patents from a separate portfolio.
