Zonar Systems, Inc. ("Zonar") is a privately held fleet-technology company founded in 2001 and headquartered in Seattle, Washington, with a distribution center in West Chicago, IL. It was majority-owned by Continental AG from 2016 (following an earlier 2015 investment by Daimler Trucks North America) until Continental sold the business to GPS Trackit — a portfolio company of Inverness Graham — in a deal announced December 2024. Zonar is now operated within GPS Trackit's portfolio; press reports put headcount at "more than 300" in North America around the time of the sale. Third-party databases list roughly 440–450 employees and an estimated revenue band of $100–230M, but Zonar does not publish financials, so those figures are unverified.
Zonar is an operating company, not an NPE. It develops and sells fleet-management telematics hardware and cloud software, including its EVIR electronic vehicle inspection system with RFID-tagged inspection points, the Zonar 2020 mobile communications tablet, GPS/asset tracking, fuel-efficiency analytics (ZFuel), the Z Pass student-ridership tracking system, and remote diagnostics such as the Virtual Technician system integrated with Daimler/Freightliner trucks. Customers span commercial trucking, pupil transportation, transit, vocational, utility, and waste/recycling fleets.
Patent-litigation posture: Zonar is an operating company defending its product business in a licensing dispute, not a serial filer. All four tracked matters stem from a single conflict with Innovative Global Systems, LLC (IGS) over a 2011 license covering IGS's U.S. Patents 6,946,953 and 7,102,494 (vehicle-to-remote data communications). Zonar appears as "plaintiff" in three PTAB entries because it filed the IPR petitions (IPR2020-00154 and -00155, filed November 19, 2019) challenging those patents after IGS sued it.
The underlying case, Innovative Global Systems, LLC v. Zonar Systems, Inc. (D.S.C., filed November 14, 2018), is a diversity breach-of-contract action seeking allegedly unpaid royalties, not a patent infringement suit — a venue and posture reflected in the single D.S.C. entry. Unified Patents classifies IGS as an "NPE (Individual)" patent owner and Zonar as a large operating company. Both IPRs were instituted and terminated by settlement in August 2020.
Inter partes review petition filed by Zonar Systems against Innovative Global Systems challenging U.S. Patent 7,102,494. The parties filed a joint motion to terminate based on settlement, and the PTAB terminated the proceeding on August 27, 2020 without a final written decision.
Inter partes review filed by Zonar Systems against Innovative Global Systems challenging U.S. Patent No. 6,946,953. The PTAB instituted review on May 12, 2020, and terminated the proceeding by settlement on August 27, 2020 before a final written decision.
Zonar Systems, Inc. filed an inter partes review petition against Innovative Global Systems, LLC. Trial was instituted on May 12, 2020, and the proceeding was terminated on August 27, 2020, on a joint motion to terminate.
