Pump Cavitation Patents: Who Leads, Where the Gaps Are 2026
Pump Cavitation and Suction Performance Patents
Concentrated at the top. The five leading assignees account for 62.5% of all 112 records in scope, and the ranked leader alone holds 33. Filings rose from zero in 2017 to a peak of 5 in 2020, then declined; the 2021-to-2024 span, the last stretch of years complete enough to compare, shows a -100% change. Figures for 2025 and 2026 are still filling in as later-filed applications publish.

Common questions on pump cavitation patents
Who holds the most patents on pump cavitation and suction performance?
Within this 112-record dataset, one assignee leads with 33 records, well ahead of the rest of the field. The top five assignees combined account for 62.5% of all 112 records in scope, and the top ten account for 82.1%, so the field is concentrated rather than evenly spread. Anyone assessing this space should treat the leading assignee’s portfolio as the primary reference point for freedom-to-operate work, not just one filer among many.
Is patent filing in pump cavitation technology increasing or slowing down?
Filing activity peaked at 5 records in 2020 and declined through the following years, with the 2021-to-2024 span — the most recent stretch that can be treated as complete — showing a -100% change. Because publication lags filing by roughly 18 months, the 2025 and 2026 figures in the dataset are still incomplete and should not be read as confirming a continued decline. The honest read is that the field cooled from its 2020 high point, not that it has stopped.
What technology areas dominate pump cavitation patent claims?
F04D, the IPC subclass covering non-positive-displacement pumps, appears in 36.6% of the 112 records in scope, making it the single largest technology cluster. B01F mixing and stirring (17.9%) and B01D separation processes (12.5%) follow at meaningfully lower shares. Because a single record can carry multiple IPC classes, these percentages add up to more than 100% and should be read as overlapping clusters rather than exclusive categories.
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 Pump Cavitation and Suction Performance 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.
