Acacia Research’s Nexus Display Technologies LLC filed its second round of litigation, this time suing Acer, ASUS, and HP and asserting four patents (5,835,498, 7,143,328, 7,295,578, 7,599,439). The entity filed its first round of litigation in July 2014, asserting the same group of patents. A range of defendants’ devices, including desktops, laptops, mobile phones, monitors, and projectors are accused of infringing the patents-in-suit. Those patents relate to transmitting video to a receiver device.
