Mine Fire Prevention and Detection Patents: Who Leads and Where the Gaps Sit
Concentrated but not locked up. the top 5 assignees hold 49.3% of all 205 records in scope, yet 89 companies appear in the ranking, so most of the field is a long tail of single- or few-filing entrants. Annual filings climbed from 14 in 2017 to a peak of 29 in 2024, a 53% rise over the 2021–2024 span. 2025 and 2026 figures are still incomplete because publication typically lags filing by around 18 months, so the recent-year dip should not be read as a slowdown.

Common questions on mine fire prevention patents
Who holds the most patents in mine fire prevention and detection?
The dataset's assignee ranking spans 89 companies, with the leader holding 36 of the 205 records in scope and the top five combined accounting for 49.3% of all records. That leaves a long tail of firms with only a handful of filings each, so while the top of the field is concentrated, most of the ranked assignees hold small, specific positions rather than broad portfolios. Anyone assessing freedom-to-operate should check both the leading filer's claims and any adjacent single-filer records in their specific sub-area.
Is patent filing activity in mine fire detection growing or slowing?
Filings rose from 19 records in 2021 to 29 in 2024, a 53% increase, which is the clearest complete-year trend in the dataset. The apparent drop in 2025 and 2026 is an artefact of the roughly 18-month lag between filing and publication, not a real slowdown, so those two years should be read as still filling in rather than as evidence of declining interest. Based on the 2017–2024 trend, activity has been on a broadly upward path over the covered period.
What patent classes cover mine fire suppression versus detection technology?
Suppression-related claims cluster in A62C (fire-fighting apparatus, 37.1% of the 205 records) and A62D (chemical protection and detoxification, 20.5%), while detection and monitoring technology spreads across G08B (signalling and alarms, 14.1%), G01J (radiation and light measurement, 9.8%) and G01N (material analysis and testing, 7.8%). Because a single record can carry multiple IPC codes, these percentages overlap and sum to more than 100%, but the relative gap between suppression and detection classes is a reliable indicator that suppression hardware and materials are more heavily claimed than detection instrumentation specifically tuned to mine fire scenarios.
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.
