Cypaleo LLC launched its first litigation campaign, suing Acer, Archos, ASUS, BlackBerry, BLU Products, Coolpad Technologies, Dell, and HTC. The entity is asserting a single patent that originated with Xerox (5,638,427). It was assigned to Cypaleo in March 2015. The patent-in-suit relates to an interactive communication device, and the complaints accuse defendants’ mobile devices, both smartphones and tablets, of infringement.
