Inventors Jinrong Yang and Ramzi Khalil Maalouf have assigned two families of patents to an entity that they created last year and, through that entity, Dareltech LLC, begun to assert those patents. The plaintiff has sued Samsung (4:18-cv-00702) over three patents generally related to managing the power consumption of displays on handheld computing devices, including cell phones, to extend battery life. Targeted are various Samsung smartphones and tablets. About a week earlier, Dareltech launched a campaign with separate lawsuits against DJI (1:18-cv-08873) and Xiaomi (1:18-cv-08729), alleging infringement of four patents generally related to a “handle for handheld terminal” by the defendants through the provision of selfie sticks.
