Princeps Interface Technologies LLC has launched its first litigation campaign, suing Alphabet (Google) (1:19-cv-01102), Apple (1:19-cv-01101), and Samsung (1:19-cv-01103) over a single patent entitled “Universal keyboard”. The NPE accuses the tech giants of infringement through the provision of mobile devices—smartphones, tablets, and/or others (e.g., Apple’s iPod)—with keyboard setup and selection features that allow users to switch between keyboards in various languages and/or a menu of emojis. Princeps Interface acquired the patent now asserted in a mid-April 2019 assignment from named inventor Timothy B. Higginson and Yuvee, Higginson’s former enterprise.
