Rockburst & Seismic Monitoring Patents: Who Leads, Gaps 2026
Rockburst and seismic monitoring patents: who is filing, and where the claim space is still open
One applicant pair dominates the citation graph. BILAK ROMAN and DUSSEAULT MAURICE B co-file together 15 times, the strongest co-assignee link in the dataset, well ahead of the next pairing at 3. Filings rise from 4 in 2017 to a peak of 8 in 2022; the 2026 figure of 0 reflects the partial year and publication lag rather than a drop in activity. With fewer than four complete years once lag is accounted for, a growth rate cannot be stated reliably from this evidence.

Common questions
Who holds the most rockburst and seismic monitoring patents?
In this dataset, BILAK ROMAN leads the ranked assignees with 16 filings, well ahead of the fifth-ranked assignee at 5 and the tenth-ranked at 2. BILAK ROMAN also co-files heavily with DUSSEAULT MAURICE B, the strongest co-assignee relationship in the data at 15 shared filings. Several Schlumberger-related entities also appear separately in the ranking, reflecting oilfield seismic-monitoring activity filed through more than one corporate name. The ranking covers 22 companies total, not a top-50 or top-100 cut.
What technology areas do rockburst patents actually cover?
Most filings sit in two IPC subclasses: G01V, geophysics and gravity surveying, at 48.9% of the 45 records, and E21B, earth and rock drilling, at 42.2%. Because a single record can carry multiple IPC codes, these shares add to more than 100%. Smaller shares cover AI-based computing methods (G06N, 13.3%), general digital data processing (G06F, 8.9%), mine safety and ventilation (E21F, 6.7%), and tunnel/shaft support (E21D, 4.4%), showing that hardware and sensing claims still outnumber learned-inference claims on the seismic signal.
Is rockburst and microseismic monitoring patent activity growing?
The recorded trend rises from 4 filings in 2017 to a peak of 8 in 2022, the highest single year in the dataset. A reliable growth rate cannot be stated because fewer than four complete years remain once the roughly 18-month publication lag is accounted for. The apparent drop toward 2026 reflects that lag rather than an actual decline in filing activity, since recent filings have not yet all published.
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 Rockburst and Seismic Monitoring 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.
