Online Water Analyzer Patents: One Leader, Thin Field 2026
- One company holds the entire ranking. SmartWash Solutions accounts for all 21 records in scope — 100% of the field, with no second filer yet visible in this dataset.
- Filing peaked in 2020, then pulled back. Thirteen of the 21 records cluster around the 2020 peak year, with momentum down sharply since — publication lag means the most recent years are still filling in.
- Sensor fouling and wash validation carry the citations. The two most-cited records concern sensor fouling mitigation and wash-process validation, pointing to where examiners and competitors are already looking.
A narrow, recently-active corner of process analytics
Online water and effluent analyzers sit at the intersection of process water monitoring and food and beverage processing hygiene. The 21 records in scope span 2015 through the 2026 cut-off, with filing concentrated around reagent consumption, cleaning-cycle validation and sludge interference — problems that arise when a plant tries to automate compliance reporting instead of relying on manual sampling. The dataset is small enough that a single assignee’s filing behaviour effectively defines the visible technology.
Because publication lags filing by roughly 18 months, the apparent drop-off after 2020 understates real activity in the most recent years; treat the tail of the trend as provisional rather than a confirmed slowdown.
Let an AI agent run this analysis on your own technology
Pick a task. Every answer cites the patents behind it.
Filing trend and technology composition
Two views of the same 21-record set: when the filings happened, and which IPC subclasses they touch.
Filing trend
Filings were flat through 2019, rose to a peak of 13 in 2020, and have since declined; 2026 is a partial year because of the data cut-off, and 2025-2026 counts will revise upward as later publications land.
IPC subclass composition
A23N (food preparation machines) covers 85.7% of the 21 records, ahead of A47J (52.4%), G01N material analysis and testing (47.6%) and C02F water and wastewater treatment (38.1%). Records commonly carry more than one class, so these shares sum above 100%.
Shares are the percentage of the 21 records in scope. A patent can carry several IPC classes, so the shares add up to more than 100%.

Methods and systems for sensor fouling mitigation
Methods and apparatus for monitoring process water within a food processing system are provided. One example water control system generally includes a temperature adjustment element with an inlet and outlet and a sensor coupled to the outlet, configured to receive a portion of process water at a first temperature and cause it to reach a second temperature at the outlet before measurement.Filed by SmartWash Solutions, LLC; published 2021-02-25.

Citation counts here are small in absolute terms and favour older filings within the searched corpus; read them as an influence signal within this dataset, not as a market-wide measure.

Three findings that shape where to look next, drawn directly from the 21-record set.
One assignee, no visible competitor
SmartWash Solutions holds all 21 records in the ranking. That is unusual even for a niche field, and it means freedom-to-operate analysis here is really a single-party analysis rather than a landscape of competing claims.
Filing pace has dropped from its 2020 peak
Activity peaked at 13 records in 2020 and has fallen off since, with the leading assignee showing a -100% year-over-year change into the latest tracked year. Given publication lag, this is a trend to monitor rather than a confirmed retreat.
Water treatment classes are a minority share
Only 38.1% of the 21 records fall in C02F (water and wastewater treatment), while food preparation machinery classes dominate. That split suggests most claims are framed around plant hygiene and process control rather than treatment chemistry itself.
Eureka can read the same corpus for gaps instead of for coverage: under-claimed branches adjacent to online water and effluent analyzers, with the prior art for and against each one.
A field defined by one applicant
The assignee ranking returns a single company across all 21 records, so the usual leader-versus-long-tail framing does not apply here — the useful question is what that company has not yet claimed.
SmartWash Solutions
Every record in the ranked set traces to SmartWash Solutions, spanning sensor fouling mitigation, wash-process validation and process water temperature control. Its filings sit mainly in food-processing hygiene rather than municipal effluent treatment.
Filing offices lean North American
Receiving offices show the United States with 6 filings and Canada with 5, followed by smaller counts in Australia, Mexico, New Zealand and two PCT filings — a filing footprint aimed at North American and Commonwealth food-processing markets rather than global coverage.
Sensor fouling draws the most attention
US20210053842A1, on sensor fouling mitigation, carries the highest citation count in the set at 2, ahead of a wash-process validation filing at 1. Both are modest counts in absolute terms but are the clearest influence signals available here.

Where to take this analysis
This landscape flags concentration and a filing peak; the next step is testing specific claim language against the sole assignee's granted claims.
Run a freedom-to-operate check
With one assignee holding the entire ranked set, a targeted claim chart against its granted patents — particularly the sensor fouling and wash validation filings — is more useful than a broad landscape scan.

In this 21-record dataset, SmartWash Solutions, LLC is the only assignee that appears in the ranking, accounting for all 21 records. That means there is no competing filer visible in the current search scope, though the field is narrow enough that a new entrant could change this quickly. Anyone assessing freedom to operate here should treat this as a single-party landscape rather than a multi-competitor one.
Filing activity in this dataset peaked in 2020 with 13 records, after several years of near-zero activity. Counts have declined since, but because publication typically lags filing by around 18 months, the drop in the most recent years is likely overstated and will revise upward as later applications publish. Treat the 2024-2026 window as provisional.
The IPC composition skews toward food preparation machinery (A23N, 85.7% of the 21 records) and kitchen/cooking utensils (A47J, 52.4%), with material analysis and testing (G01N, 47.6%) and water/wastewater treatment (C02F, 38.1%) also represented. Because a single record can carry multiple IPC classes, these percentages sum above 100% and should not be read as a strict breakdown of the field.
US20210053842A1, filed by SmartWash Solutions and published 2021-02-25, covers methods and apparatus for monitoring process water in a food processing system, including a temperature adjustment element and a sensor positioned at its outlet to measure process water after a controlled temperature change. It is the most-cited record in this dataset at 2 citations. Anyone building a competing sensor-fouling mitigation approach should check this filing's specific temperature-control mechanism before assuming a clear path around it.
Yes — the current 21-record set shows dense claiming around sensor fouling and wash-process validation but comparatively little direct claim activity on sludge interference compensation, reagent consumption optimisation, and automated regulatory reporting formats. These adjacent branches show up in the search terms but not heavily in the granted claim language reviewed here, making them worth a closer novelty search before committing to a filing strategy.

Patent data carries inherent limitations: recent filings (typically the most recent 18–24 months) are under-counted due to standard publication lag; counts may be reported at either a patent-family or a patent-record basis and are not always directly comparable; classification, applicant-name, and citation data may contain errors, duplicates, or omissions; and the underlying search query defines and constrains the scope shown.
