Frac Pumping Patents: Who Leads, Where the Gaps Are 2026
Frac pumping equipment patents: who holds the fluid end, and where filing has slowed
78.5% concentration. The top 5 of 52 ranked assignees hold 520 of 662 records in scope — filing here is dominated by a small group, not a fragmented field. Filings rose from 20 in 2017 to a peak of 144 in 2021, then fell to 54 by 2024 — a 63% decline over that three-year span. 2025 and 2026 figures are still incomplete due to publication lag and should not be read as a continued decline until later data confirms it.

Common questions on frac pumping patents
Who are the leading patent holders in frac pumping equipment?
The assignee ranking for this dataset covers 52 companies, and it is heavily concentrated: the top 5 hold 520 of 662 records in scope, or 78.5%. The leading single assignee alone holds 235 records, far ahead of fifth place at 29. This means most of the mechanical pump architecture — fluid ends, plunger packing, manifolds — is already claimed by a small group, and any new filer should expect to encounter their prior art directly rather than file into open space.
Why did frac pumping patent filings fall after 2021?
Filings peaked at 144 in 2021 and fell to 54 by 2024, a 63% decline over that three-year span, with several leading assignees showing year-over-year drops of -82% to -100% in the most recent complete year. This likely reflects the initial wave of electric-fracturing-fleet patenting working through prosecution rather than the field disappearing. Figures for 2025 and 2026 are still incomplete because publication typically lags filing by around 18 months, so the most recent years should not yet be read as a continuing decline.
What technology areas dominate frac pump patent claims?
E21B (earth and rock drilling, wells) appears in 77.8% of the 662 records and F04B (positive-displacement pumps) in 55.4%, making mechanical pump architecture the dominant claim territory. Turbine and electric-drive-related classes are present but much thinner: F02C at 11.0%, F01D at 9.5%, and H02P (motor and generator control) at 4.5%. Because a single record can carry multiple IPC classes, these shares overlap and add to more than 100%.
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 Frac Pumping Equipment and Pressure Pumping 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.
