Blast vibration and airblast control patents: who holds the ground and what is still open
72.9% of all 48 records sit with just five assignees — this field is concentrated at the top, not fragmented. Filings moved from 0 in 2017 to a peak of 3 in 2022, with 2026 at 2 on a partial year. With fewer than four complete post-lag years to compare, no growth rate can be stated reliably from this trend alone.

Common questions on blast vibration and airblast patents
Who holds the most patents in blast vibration and airblast control?
The ranking covers 26 assignees across the 48 records in scope, and it is heavily top-weighted: the leading assignee alone holds 14 records, and the top five combined account for 72.9% of all records. Beyond the top ten, which together reach 93.8%, filing counts drop off quickly into single- or low-digit totals. This structure means a competitive check should focus first on the handful of leaders rather than the full ranked list.
What technology areas dominate blast vibration patent claims?
Geophysics and surveying (IPC class G01V) appears in 62.5% of the 48 records, making it the single most common classification, ahead of the core blasting class F42D at 31.3% and material testing (G01N) at 29.2%. This shows that patent activity concentrates on how ground vibration and airblast are sensed, modelled and monitored, rather than solely on new blasting methods. Railway-related classes B61L and B61K also show up in roughly a quarter of records, reflecting overlap with rock-fall and structural monitoring near rail infrastructure.
Is the blast vibration and airblast control patent field growing?
The filing trend shows activity moving from 0 in 2017 to a peak of 3 in 2022, with 2 recorded so far in 2026 on a partial year. There are not enough complete post-lag years in the data to state a reliable growth rate, and because publication typically lags filing by around 18 months, the most recent years understate real activity. Treat any apparent flattening in the last one to two years with that lag in mind rather than as a definitive slowdown.
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 Blast Vibration and Airblast Control 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.
