Gas Liquid Dispersion Patents: Top Companies & Filing Trends 2026
Gas Liquid Dispersion and Mass Transfer Patents
31.0% of the field sits with five companies. 162 of 522 records in scope trace to the top five assignees, with the leader alone holding 42 — filing here is concentrated, not evenly spread. Filings rose from 5 in 2017 to a peak of 44 in 2019, then declined; the 2021-to-2024 window shows a 37% drop (27 to 17), the most recent span that is not distorted by publication lag.

Common questions about this landscape
Who holds the most patents in gas liquid dispersion and mass transfer?
Filing is concentrated at the top: the leading assignee in this dataset holds 42 of the 522 records in scope, and the top five combined hold 162 records, or 31.0% of the field. That concentration is heaviest in bioreactor and fermentation apparatus classes rather than spread evenly across all mixing hardware. A freedom-to-operate review should start by mapping the leading filers’ granted claims before running a broader novelty search.
Is patent filing in this field growing or shrinking?
The last reliable comparison shows a decline: filings dropped from 27 in 2021 to 17 in 2024, a 37% fall over that three-year span, after peaking at 44 in 2019. Figures for 2025 and 2026 are still incomplete because publication lags filing by roughly 18 months, so they should not be read as confirming a further drop. Based on complete-year data through 2024, the trend is a real pullback from the 2019 peak.
What technology areas dominate gas liquid dispersion patents?
Bioreactor and enzyme apparatus claims (IPC class C12M) touch 51.0% of the 522 records in scope, more than double the next largest class, fermentation and enzymatic synthesis (C12P) at 23.6%. Mixing and stirring hardware (B01F) and separation processes (B01D) are comparatively thin at 13.8% and 8.2%. This means claim pressure sits heaviest at the vessel and bioprocess-application level, with more room at the hardware-mechanism level.
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 Gas Liquid Dispersion and Mass Transfer covering 2015–2026, data cut-off 2026-07-31.
