1 case as defendant.
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.
IGS filed a contract/royalty dispute against Zonar Systems in D.S.C. The matter referenced patents 6,946,953 and 7,102,494; the court ruled on Zonar's motion to dismiss/summary judgment in 2019.
