Princeps Secundus LLC has filed suit against Lenovo (Motorola Mobility) (1:20-cv-00318) in the Northern District of Illinois, completing the shift of the entire campaign out of Delaware, where initial cases were filed against Motorola Mobility, as well as Alphabet (Google) and Apple last summer. The initial plaintiff, Princeps Interface Technologies LLC (PIT), transferred the asserted keyboard patent to Princeps Secundus after those initial cases were filed—and dismissed without prejudice. Targeted throughout has been the defendants’ 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.
