A recall is a reserve before it's a headline, and OTA is the tool that can shrink the draw. On July 6, 2021, Hyundai was granted US11055083B2, "Method and apparatus for updating vehicle software using OTA." The CPC mix — G06F 8/65 (software update), B60R 16/023 (vehicle data networks), H04L 67/34 and H04W 4/40 (telematics) — is the over-the-air delivery stack.The economics are simple in direction: a software fix pushed over the air costs a fraction of one delivered through a dealer. As more recalls become software recalls, the OTA pipeline becomes the difference between a manageable campaign cost and an expensive one. The patent is part of that pipeline.The honest caveat is that capability is not realized savings. A grant tells you Hyundai built the mechanism; the actual recall-cost experience lives in the warranty and campaign lines of the filings. An analyst should treat the patent as a reason to watch those lines, not as a substitute for them.For the ledger reader, the move is to connect the OTA capability to the recall-reserve mechanism and then verify against disclosures. The primary source for any campaign or reserve claim is the SEC filing on sec.gov, surfaced via SEC filings as the evidence index.Read it as a 2021 recall-economics marker. The receipt is in the warranty experience that follows — the grant only tells you the cheaper path was being built.
