Jet Pump and Hydraulic Lift Patents: Concentration at the Top, a Long Tail Below
80% of the field sits with five assignees. The top 5 combined account for 32 of the 40 records in scope, while the ranked list runs to only 13 companies before the tail runs out entirely. Filings rose from zero in 2017 to a peak of 9 in 2020, then declined; the 2021-to-2024 span alone shows a -100% move, from 3 down to 0. Treat 2025 and 2026 as incomplete rather than as evidence the field has gone quiet.

Common questions about this landscape
Who holds the most jet pump and hydraulic lift patents?
The ranked list of 13 companies is led by a single assignee holding 11 of the 40 records in scope, well ahead of the rest of the field. The top 5 assignees combined hold 32 records, or 80.0% of the total, and the top 10 combined reach 100.0% of all records. This means the field is dominated by a small group rather than spread across many independent filers, so a competitive review should start with that top group rather than a broad market scan.
Is the jet pump and hydraulic lift patent field still active?
Filing activity peaked at 9 records in 2020 and has since declined, with the tracked 2021-to-2024 span showing a full -100% drop from 3 filings to 0. However, publication lags filing by roughly 18 months, so the most recent one or two years in the trend are understated by definition and should not be read as proof the field is dead. A fuller picture will only be visible once 2025 and 2026 filings finish publishing.
What technology areas dominate jet pump and hydraulic lift filings?
E21B, the earth and rock drilling / wells classification, appears on 72.5% of the 40 records in scope, confirming that most patents are anchored in physical wellbore hardware such as pump mechanisms and hydraulic subs. A secondary cluster involves digital processing and control classifications — G06F at 22.5% and G05B at 5.0% — indicating that a meaningful minority of filings pair mechanical lift hardware with monitoring or control logic. Because a single record can carry multiple classifications, these percentages add up 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.
