Slurry & Chemical Blending Patents: Top Companies & Trends 2026
Slurry and Chemical Blending Distribution Patents
Concentrated at the top. Five assignees hold 78.8% of the 292 records in scope, and ten hold 91.1% — a field with a dominant core and almost no long tail beyond it. Filings climbed from 7 in 2017 to a peak of 80 in 2022, then dropped fast — the 2021-to-2024 change is -98%. Because publication lag means 2025 and 2026 are undercounted by design, this reads as a genuine post-2022 pullback in new filing activity through the last complete year, not as a technology in decline.

Common questions about this landscape
Who are the leading patent holders in slurry distribution and chemical blending systems?
The assignee ranking in this dataset covers 45 companies by patent family, and it is heavily front-loaded: the top five combined hold 78.8% of all 292 records in scope, with the leading assignee alone accounting for 152. The drop-off after the leader is steep — fifth place holds only 13 records — so this is a field led by a small, entrenched core rather than a broad competitive set. Anyone assessing freedom to operate should start with that leader’s portfolio before looking further down the ranking.
Is the number of new patent filings in this space still growing?
Filing activity rose from 7 records in 2017 to a peak of 80 in 2022, then fell sharply — the change from 2021 to 2024 is -98%. However, publication typically lags filing by around 18 months, so 2025 and 2026 figures in any dataset will look artificially low regardless of actual filing activity. Treat 2024 as the last complete year and read the recent pullback as real through that point, without assuming the technology has stopped attracting filings entirely.
What does US5924794A actually cover, and does it block new designs?
US5924794A describes a chemical blending system built around a mix tank, a recirculation line with a pump, separate diluent and concentrated-chemical supply lines feeding into that recirculation line, and a conductivity-type sensor providing continuous concentration measurement. It is the most-cited record in this landscape at 98 citations, which signals strong influence on later filings in the field rather than automatic blocking power over every blending design. Whether it constrains a specific new system depends on whether that system uses the same recirculation-line sensing and dual-inlet architecture the claims describe, which requires a claim-by-claim comparison rather than a keyword match.
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 Slurry and Chemical Blending Distribution 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.
