Fractus SA has resumed litigation, accusing ADT (2:22-cv-00412) and Vivint Smart Home (Vivint) (2:22-cv-00413) of infringing overlapping sets of nine antenna systems patents through the provision of a wide array of devices, ranging from smart home hubs to cellular modules, that incorporate certain antenna structures. This campaign began back in May 2009, with its last open suit, filed against TCL (TCT Mobile) in April 2020, dismissed with prejudice in light of a noticed settlement this past January. Other defendants have included LG Electronics, Samsung, and ZTE.
