Honeywell International Inc. (NASDAQ: HON; commonly "Honeywell") is a publicly traded U.S. industrial technology company headquartered at 855 South Mint Street, Charlotte, North Carolina. The Honeywell brand dates to 1906; the current Delaware corporation was incorporated in 1985 and took its present form through the 1999 AlliedSignal–Honeywell merger. Per its FY2025 Form 10-K, Honeywell employed about 101,000 people and reported sales of roughly $37.4 billion. It is a standalone public company, not a subsidiary or shell; market capitalization has run in the $130–140 billion range in 2026.
Operations span four reported segments in 2025: Aerospace Technologies (aircraft propulsion, cockpit and navigation systems, auxiliary power); Building Automation (fire, access/security, controls and building-management hardware/software); Industrial Automation (sensors, smart edge devices, warehouse and workflow automation); and Energy and Sustainability Solutions (process technology, catalysts, refining/petrochemical technologies). Two separations are underway: Solstice Advanced Materials was spun off on October 30, 2025, and Aerospace Technologies is slated to separate into an independent public company in 2026.
Patent-litigation posture: an operating company defending, not asserting. Honeywell is a defendant in both tracked cases and a plaintiff in none — the profile of a large product-selling manufacturer being attacked, not an NPE. Neither venue is a notorious plaintiff-friendly district: one is a U.S. International Trade Commission Section 337 investigation, the other a District of Oregon (Portland Division) action.
Notable cases: Furuno Electric Co., Ltd. v. Honeywell International Inc. (D. Or.; ITC Inv. No. 337-TA-810), both filed 2011-09-30. Furuno, a Japanese marine-electronics manufacturer, asserted four patents (U.S. 6,084,565; 7,095,367; 7,089,094; 7,161,561) against Honeywell and its U.K. subsidiary Skyforce Avionics Ltd.; the USITC described the accused products as aircraft and helicopter heading/position navigation displays. The filings followed Honeywell's own 2009 Minnesota district court suit and June 2011 ITC complaint (337-TA-783) against Furuno over GPS navigation patents, making this part of a two-way navigation-IP dispute; only the Furuno-filed actions appear in this database.
