Fluorine-Free Firefighting Foam Patents: Who Leads the Field 2026
- Four assignees account for all 17 records in scope, with a single leader holding 8 — this is a concentrated field, not a fragmented one.
- Filing peaked in 2022 at 11 records and has since cooled, though the most recent years are understated by publication lag.
- Fire-fighting (A62C) and chemical protection (A62D) classes cover most of the corpus, while polymer chemistry and detergent formulation classes each touch only a single record.
What the fluorine-free foam patent record shows
Fluorine-free firefighting foam formulation covers concentrates and foam-forming compositions built around hydrocarbon and siloxane surfactants, designed to replace fluorosurfactant-based AFFF while still meeting expansion ratio, drainage time and burnback resistance benchmarks. The dataset in scope spans 2015 to 2026 and contains 17 published records, a small but tightly clustered corpus rather than a sprawling one.
Filing is concentrated among a handful of assignees rather than spread across a long tail of entrants, and the technology classification skews heavily toward fire-fighting apparatus and chemical protection rather than base polymer chemistry — suggesting most claimed innovation sits in formulation and application rather than novel chemical backbones.
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
Publication dates lag filing by roughly 18 months, so figures for the most recent years understate actual filing activity.
Filing activity peaked in 2022
Records climbed from zero in 2017 to a peak of 11 in 2022, then declined — consistent with an initial wave of formulation patents followed by consolidation among fewer filers. The 2026 figure is partial because the data cut-off is mid-year.
Fire-fighting and chemical protection dominate the classification
A62C (fire-fighting) appears on 76.5% of the 17 records and A62D (chemical protection & detox) on 47.1%, while C08G (condensation polymers) and C11D (detergents & cleaning compositions) each appear on just one record. Because records can carry multiple IPC classes, these shares add up to more than 100% of the record total.
Shares are the percentage of the 17 records in scope. A patent can carry several IPC classes, so the shares add up to more than 100%.

With all 17 records attributable to four assignees, this field rewards watching a small set of competitors closely rather than scanning for a long tail of new entrants.
The whole field sits with four filers
The assignee ranking returns only four companies, and together they account for every one of the 17 records in scope. There is no unranked long tail here — competitive tracking in this niche means tracking these few filers directly, not scanning for new entrants.
Activity has cooled since 2022
Filing rose from zero in 2017 to a peak of 11 records in 2022, then eased off. Because publication lags filing by around 18 months, the apparent decline in the most recent years overstates any real slowdown.
Claims concentrate on apparatus and chemical safety, not base chemistry
Most records classify under fire-fighting apparatus or chemical protection rather than under polymer or detergent chemistry classes, which each touch only a single record. That imbalance points to formulation and delivery-system claims as the crowded ground, with base chemical innovation comparatively open.
Eureka can read the same corpus for gaps instead of for coverage: under-claimed branches adjacent to fluorine-free firefighting foam formulation, with the prior art for and against each one.
Who holds the claim space
A single leader holds 8 of the 17 records, with the remaining three ranked assignees splitting the rest — a structure closer to an oligopoly than an open field.
One assignee holds nearly half the corpus
The leading filer accounts for 8 of the 17 records in scope, roughly half the entire dataset. Any freedom-to-operate review in this space should start with that portfolio.
Filing is anchored in the United States
The United States receives the largest share of filings, with Europe and the PCT route each drawing four. This suggests the US is the primary commercial battleground for fluorine-free foam formulations.
No ranked assignee shows fresh activity
All tracked assignees, including the leader, show zero filings in the latest year, with one recording a -100% year-on-year change. Given publication lag, this likely reflects reporting delay rather than a genuine halt in R&D.

Where to take this next
The dataset points to a concentrated but formulation-heavy field with open ground in base chemistry.
Map the leader's full portfolio
With one assignee holding 8 of 17 records, a claim-by-claim review of that portfolio is the fastest way to identify where new formulation work would infringe versus where it is clear.

The assignee ranking for this dataset returns four companies covering all 17 records in scope, with one filer holding 8 of them. This is a concentrated field rather than one with many small filers, so competitive monitoring is practical: tracking four portfolios covers the entire documented landscape. Any new entrant would be filing into a space where nearly half the existing claims sit with a single company.
Most records classify under fire-fighting apparatus (A62C, 76.5% of the 17 records) or chemical protection and detoxification (A62D, 47.1%), rather than under base polymer or detergent chemistry, which each appear on only one record. This suggests the bulk of patented innovation addresses formulation performance and delivery systems — expansion ratio, drainage time, burnback resistance — rather than novel surfactant backbones. A filer aiming at core chemistry rather than application engineering may find more open ground.
Filing activity rose from zero records in 2017 to a peak of 11 in 2022, then declined in subsequent years. However, publication typically lags actual filing by around 18 months, so the apparent recent slowdown, including zero recent-year activity across all tracked assignees, likely overstates any real pullback in R&D. Readers should treat the last one to two years of any filing trend as provisional rather than final.
WO2025207910A1, filed by Perimeter Solutions LP and published in October 2025, claims fluorine-free firefighting foam compositions with improved low-temperature stability, covering concentrates, foam-forming compositions and solutions suitable for Class A foams, high-expansion foams and vehicle systems. Anyone developing cold-climate or vehicle-mounted foam systems should review its specific claim scope directly, since low-temperature stability is a fairly narrow performance axis that this filing appears to target deliberately. It does not, on its own, cover the whole fluorine-free foam field.
The thinnest coverage in this corpus sits in condensation polymer chemistry (C08G) and detergent/cleaning composition classes (C11D), each appearing on only a single one of the 17 records, compared with the much denser fire-fighting apparatus and chemical protection classes. That gap points to base surfactant chemistry and cross-compatibility with cleaning formulations as under-claimed relative to application and delivery engineering. A first claim there would need to differentiate on the underlying chemical composition rather than on nozzle, system or expansion-ratio parameters, which are already densely claimed.
