Four among the roughly 60 patents that Toshiba divested to Four Batons Wireless LLC in June 2021 have now appeared in litigation. In a new Eastern District of Texas complaint, Four Batons accuses Samsung (2:24-cv-000284) of infringing those mobile communications patents through the provision of products—with the Samsung Z Flip 5 smartphone identified as the exemplary accused product—that support dual concurrent Wi-Fi, multiple heterogeneous radio interfaces, the WPA3 security certification standard, and the Samsung Intelligent Wi-Fi feature.
