Perforating Systems Patents: Who Leads, Where the Gaps Are 2026
Perforating Systems and Shaped Charges: Patents, Leaders and Filing Trends
Five companies hold more than half the field. The top 5 assignees combine for 2,494 of 4,496 records in scope — 55.5% — with the top 10 reaching 78.7%. From a 2017 peak of 233 published records, volume declined to 68 in 2024 (the last complete year), a drop of 63% from the 186 filed in 2021. Treat 2025 and 2026 figures as provisional — publication typically lags filing by around 18 months, so the tail of the chart will keep filling in rather than representing a real collapse.

Common questions on perforating system patents
Who holds the most patents on perforating guns and shaped charges?
Filing is concentrated among a small group of oilfield service companies rather than spread evenly across the field. The top 5 assignees in this dataset together hold 2,494 of 4,496 records in scope, which is 55.5% of the field, and the top 10 extend that to 78.7%. The single leading assignee alone holds 766 records, well ahead of the fifth-ranked company at 313, so any competitive or freedom-to-operate review should start with that top group before looking at the long tail of smaller filers.
Is the perforating gun and shaped charge patent space still growing?
No — filing volume peaked in 2017 at 233 published records and has declined since, with confirmed filings falling from 186 in 2021 to 68 in 2024, a 63% drop over that span. That decline is more consistent with a maturing, densely claimed core than with a shrinking market. Figures for 2025 and 2026 are still incomplete because publication typically lags actual filing by around 18 months, so the most recent years will continue to fill in and should not be read as a continuing collapse.
What is the difference between E21B, F42B and F42D classifications in this field?
E21B covers earth and rock drilling, including wellbore tools, and touches 89.6% of the 4,496 records in this dataset, reflecting that most filings frame the invention primarily as downhole well equipment. F42B covers ammunition and explosive charges and appears in 21.3% of records, while F42D covers blasting and appears in 16.3%; these two classes capture the shaped-charge and detonation mechanics specifically. Because a single record can carry multiple IPC classes, these percentages add up to more than 100% and should not be summed or treated as mutually exclusive shares.
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 Perforating Systems and Shaped Charges 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.
