2-Way Computing, Inc. has added three more defendants to its litigation campaign in Nevada: Atos (Unify) (2:16-cv-00423), Polycom (2:16-cv-00419), and ShoreTel (2:16-cv-00420). Each of the NPE’s complaints asserts the only patent that USPTO assignment records indicate that it owns (5,434,797). The ‘797 patent generally relates to an audio communication system for a computer network not using traditional telephone lines. 2-Way is asserting it against the defendants’ IP phones.
