TeleType Co., Inc. (trading as TeleType GPS / "TeleType Company") is a privately held U.S. software and hardware developer headquartered at 44 School Street, Boston, Massachusetts. It was founded in 1981 in Ann Arbor, Michigan, as TeleTypesetting Company Inc. by Edward Friedman (president) and Marleen Winer (vice president). No public ticker, parent, or disclosed funding; it appears to be founder-owned. Size estimates vary by third-party source and are not authoritative: employee counts range from 5 (Tracxn, 2024) to 10–49 (Thomasnet) to 51–200 (ZoomInfo), and Thomasnet lists annual sales of roughly $1–4.9M (Kona Equity shows about $5.4M). Treat these as unverified.
Operations. TeleType develops GPS navigation systems and software, specializing in commercial-vehicle routing. Its main current products are the WorldNav Truck GPS device line (mirroring truck restrictions such as bridge heights, weight limits, and hazmat rules) and the smartphone app family SmartTruckRoute, SmartBusRoute, and SmartRVRoute for Android/iOS. It also offers WorldNav navigation software for PC/Windows CE, an SDK/API for customization, GPS receivers and tracking units (e.g., the earlier PocketTracker), and engineering/consulting services. Historical product lines included phototypesetting interfaces (MicroSetter) and Apple Newton digital-book titles. This is an operating company, not a shell or patent-assertion entity, and Wikipedia notes it holds a pending patent on custom routing (US 2010/0057358).
Litigation posture. The only tracked case is one in which TeleType is a defendant (0 plaintiff cases), consistent with an operating company being targeted rather than asserting. In Navog LLC v. TeleType Co., Inc. (1:25-cv-10394, D. Mass., filed 2025-02-17, Judge Richard G. Stearns), plaintiff Navog LLC asserted U.S. Patent 10,593,205 ("GPS and warning system") on an inducement theory tied to TeleType's product literature and website. Navog is characterized by Unified Patents as an NPE and "entity of Eric Zautner"; the same patent has been asserted against Garmin, TomTom, Sygic, Panasonic, Trimble, Rand McNally, Verizon, and Samsara. Navog's other suits have clustered in plaintiff-friendly venues including the E.D. Tex.; the TeleType case was filed in D. Mass. and was voluntarily dismissed without prejudice on 2025-05-20 under FRCP 41(a)(1)(A)(i), before TeleType answered. No merits ruling was made.
