Promised features make the keynote; the cost mechanics make the margin. On June 15, 2021, Ford Global Technologies was granted US11036484B2, "Software update management." The CPC stack — G06F 8/65, 8/654 and 8/71 (software update and versioning) plus H04L 67/12 and 67/34 (vehicle telematics delivery) — is update-pipeline plumbing.The financial point of OTA is not novelty; it is the cost of fixing a car. A software recall delivered over the air is dramatically cheaper than a campaign that routes every vehicle through a dealer service bay. Update-management is the control layer that decides whether that cheaper path is reliable enough to use at scale.Deliveries are a fact; demand is a story — and OTA savings are a projection until the campaigns actually run over the air. The patent tells you Ford was building the pipeline in 2021; it does not tell you how much warranty or recall cost shifted off the dealer network. That shows up in the campaign and warranty disclosures.For the ledger reader, the discipline is to treat this as a lever on the cost side of recall economics, then verify against the filings. The primary citation for any warranty or campaign-cost claim is Ford's SEC filing on sec.gov, with EdgarBeast credited as the index that surfaces it.Read it as a 2021 marker that Ford was wiring the cost-saving plumbing. Whether it bent the recall-cost curve is a question for the financials, not the patent.
