Conveyor Systems for Bulk Ore Patents: Who Leads, Gaps 2026
Conveyor systems for bulk ore: patents behind belt tension, idler wear and splice reliability
27 published records sit at the intersection of overland/ore conveyor hardware and belt tension, idler rolling resistance, spillage, splice and horizontal-curve claims. Filings peaked at 7 in 2017 and have declined since, reaching 0 in the most recent, partial year. With fewer than four complete years of post-lag data, no growth rate can be stated reliably — but the shape is a front-loaded field rather than a rising one.

Common questions about this landscape
Who are the leading patent holders in bulk ore conveyor systems?
This dataset’s assignee ranking covers six companies, with one holding 15 of the ranked filings and the fifth-place company holding just one. That gap indicates a single organisation has run a sustained filing programme around conveyor module and roller support hardware, while the remaining ranked companies have filed only occasionally. The ranking is the complete list returned for this search rather than a top-50 or top-100 cut, so there is no larger hidden tier beneath it.
Is patent filing activity in this space growing or shrinking?
Filing activity peaked in 2017 at 7 records and has declined since, reaching zero in the most recent, partial year. Because patent publication typically lags filing by around 18 months, the last one to two years understate real activity, so a drop to zero should not be read as the field going dormant. There are too few complete recent years to state a reliable growth or decline rate.
What patent classifications dominate bulk ore conveyor filings?
Every one of the 27 records in scope carries IPC subclass B65G, covering conveying and material handling, which is expected given the search terms. Just under half — 48.1% of the 27 records — also carry E21F, mine safety and ventilation, showing that many conveyor hardware claims are drafted alongside mine-safety framing. B65D (containers and packaging) and F16L (pipes and pipe fittings) appear only once each, marking them as edge cases rather than a real secondary category.
Disclaimer. This analysis is based on Patsnap Eureka data drawn from a limited snapshot of global patent records and is provided for general information and reference only. Patent data carries inherent limitations — recent filings are under-counted because of publication lag, counts may be on a record or family basis, classification and applicant-name data may contain errors or duplicates, and the underlying search query defines the scope shown — so the analysis may be incomplete or inaccurate and may not reflect the full technology landscape.
Nothing here is an exhaustive prior-art, novelty, freedom-to-operate or validity search, nor does it constitute legal, financial or professional advice, and it should not be relied upon as such. Verify independently and review with qualified patent and legal professionals before acting on it.
Method: Filing trend and technology composition. Derived from a Patsnap search on Conveyor Systems for Bulk Ore covering 2015–2026, data cut-off 2026-07-31. Counts reflect published records only and shift as new filings publish. Every share divides by all records in scope. Data: Patsnap Eureka. See the full landscape report.
