Irrigation Water Filtration Patents: Leaders & Filing Trends 2026
Irrigation Water Filtration Patents: Who Holds the Claims and Where They Cluster
Concentrated at the top. The leading assignee alone accounts for 8 of the 33 records in scope, and the top 5 combined hold 57.6% of all records. Filings run from 2 in 2017 to a peak of 4 in 2023, with 1 recorded so far in 2026. With fewer than four complete years available once publication lag is factored in, a growth rate cannot be responsibly computed from this trend.

Common questions on irrigation water filtration patents
Who are the leading patent holders in irrigation water filtration?
The ranked dataset covers 19 companies across 33 records in scope. One assignee leads with 8 records, well ahead of the field, and the top 5 combined hold 57.6% of all records. Below the top 10 — which together hold 81.8% of records — the ranking thins into single-filing entrants, so the field has a concentrated leadership group sitting above a long tail rather than dozens of comparably sized competitors.
What patent classes cover irrigation filtration technology?
The two dominant IPC subclasses are B01D (separation processes, including filtration) and C02F (water and wastewater treatment), each present in 57.6% of the 33 records, indicating most filings combine mechanical filtration with a water-treatment framing. Supporting classes include A01G (horticulture and forestry, 15.2%), F04B (pumps, 12.1%) and G05D (control systems, 6.1%), with A01C, C05F and E03B each appearing in a single record.
Is patent filing activity in irrigation filtration growing?
The trend runs from 2 filings in 2017 to a peak of 4 in 2023, with 1 recorded so far in 2026. Because publication lags filing by roughly 18 months, the last one to two years in any dataset understate true activity, and there are fewer than four complete years of data available once that lag is accounted for — so a reliable growth rate cannot be stated from this evidence.
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.
