RO Plant Automation Patent Snapshot 2026
The RO plant automation patent corpus is small and highly concentrated, with Fluence Water Israel Ltd holding the largest share of the top-ranked filers and the United States as the dominant filing jurisdiction. Annual volume peaked in 2017 and has since eased, signalling a maturing rather than expanding competitive front.
Fluence Water Israel leads a tightly held corpus
Fluence Water Israel Ltd sits at the top of the applicant ranking, followed by Water Solutionz Int and Gambro Lundia AB. The top five filers together account for 75% of the combined total across the ranked applicants visible in this query, indicating a highly concentrated visible assignee structure for this niche.
The tier gap between the leader and the rest is pronounced: Fluence Water Israel Ltd holds 8 patent records, while the next-ranked applicant holds 5. Below the top two, volumes drop quickly, and several entrants — including academic institutions from India — hold only a single record each, suggesting limited depth beyond the front tier.

The leaders’ positions imply that proprietary process-control and filtration-monitoring IP is largely locked up by a small number of commercial water-technology firms, leaving limited room for incremental improvement patents without differentiated technical angles.
Filing counts for the most recent 18–24 months should be treated as preliminary given standard patent-publication lag; the 2025 uptick in particular may grow as pending applications publish. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
Activity peaked in 2017; filtration and water-treatment IPC classes dominate
The annual filing trend reveals a burst of activity in 2017 followed by prolonged quiet, while the technology composition shows overwhelming concentration in two IPC branches. Together these charts frame a field that is technically narrow and past its primary filing cycle.
Annual filing trend
Filings spiked to six records in 2017, then fell to near-zero for several years, with a modest 2025 uptick that should be read cautiously given publication lag. The overall pattern confirms the lifecycle evidence that annual volume has eased from its 2017 peak.

C02F (water and wastewater treatment) and B01D (separation and filtration processes) collectively account for the vast majority of IPC classifications, confirming that automation IP here is rooted in membrane process control rather than broader digital or AI frameworks. The remaining branches — A61M, C12Q, and G06N — each hold only a single record.

Containerized desalination system
A water desalination system includes a first set of ultrafiltration membranes, a second set of ultrafiltration membranes, a first backwashing system configured to treat at least one of the first set of ultrafiltration membranes or the second set of ultrafiltration membranes with brine generated by a reverse osmosis process, and a second backwashing system… (excerpt from the patent abstract)

Ranked by total forward citations. Citation counts favour older and broadly cited patent families, and broad or adjacent patents may appear when they match the search scope.

Some patent titles may be shown in their original, non-English language where an accurate translation could not be guaranteed.
Assignee snapshot from the current evidence set
The applicants below are visible in this query result. Because the evidence set is relatively small, read this section as a directional snapshot rather than a full competitive ranking.
Fluence Water Israel Ltd
Fluence Water Israel Ltd holds 8 patent records, the largest share in this corpus. Its technology focus clusters tightly around B01D 29 (filtration), B01D 61 (membrane separation), and B01D 65 (membrane maintenance) — all core to automated RO process control. No applicant momentum data is available to characterize recent trajectory.
patent records: 8Water Solutionz Int
Water Solutionz Int holds 5 patent records and covers a similar IPC spread — B01D 61, B01D 65, and C02F 1 — indicating it competes on overlapping technical ground with the leader. The gap of 3 records between leader and challenger is meaningful given the small corpus size. No applicant momentum data is available.
patent records: 5Frequently asked questions
The corpus covers 14 patent families in scope. This is a niche area with limited filing volume compared with broader water-treatment or membrane-technology domains.
Fluence Water Israel Ltd leads the applicant ranking with 8 patent records, well ahead of the next-ranked filer, Water Solutionz Int, which holds 5 patent records.
The United States is the leading jurisdiction with 8 patent records. WIPO PCT filings number 5, Israel holds 4, and India holds 4. Europe (EPO), Australia, Canada, Mexico, and Malaysia each have 1–2 records.
The field is assessed as being in Decline. Annual filings peaked in 2017 at 6 records and have eased significantly since, with a recent-window growth rate of -50%. A small 2025 uptick is subject to publication lag and should not yet be read as a reversal.
C02F (water and wastewater treatment) and B01D (separation and filtration processes) are the visible classes, with 26 and 25 patent-record-level classifications respectively. AI/computing (G06N), biomedical devices (A61M), and enzymatic testing (C12Q) each appear only once.
No co-applicant filings are recorded in this corpus. All identified filers appear to have filed independently, which includes commercial firms, individual inventors, and academic institutions in India.
