Precision Fermentation Oxygen Transfer Patents: Leaders & Trends 2026
Precision Fermentation Oxygen Transfer: Patents Behind Mass-Transfer Engineering
33.5% concentration. The top 5 assignees hold 301 of 898 records in scope — a field with a clear leader and a long tail of single- or few-filing entrants. Filings ran from 57 in 2017 to a peak of 62 in 2019, then continued through complete-year growth of 29 (2021) to 39 (2024), a 34% rise over that span. 2025 and 2026 figures are still incomplete due to publication lag and understate true filing activity.

Common questions on this landscape
Who holds the most patents in precision fermentation oxygen transfer?
One assignee leads clearly with 98 of the 898 records in scope, built around gas-fermentation bioreactor design and control. The top 5 assignees combined hold 301 records, or 33.5% of the field, after which filing volume drops off quickly into a long tail of companies with only a handful of filings each. This pattern points to a field with a dominant early mover but plenty of room for new entrants to stake claims outside its core hardware.
Is patent filing in this space growing or slowing down?
Complete-year data shows growth: filings rose from 29 in 2021 to 39 in 2024, a 34% increase over that span, after an earlier peak of 62 in 2019. The apparent decline in 2025 and 2026 is a publication-lag artefact — patents typically publish about 18 months after filing, so the most recent one to two years always look understated. Treat 2024 as the last reliable complete year for trend reading.
What technology areas get the most patent claims in this field?
Bioreactor and apparatus design (IPC class C12M) covers 72.9% of the 898 records, the largest share by a wide margin, followed by fermentation and enzymatic synthesis process claims (C12P) at 58.7% and microorganism/genetic engineering claims (C12N) at 39.9%. Smaller but present branches include food applications, peptide/protein claims, separation processes, and medicinal preparation uses — each in the 6-8% range. This tells you claim activity is weighted toward the physical reactor and gas-delivery hardware more than the downstream biological process.
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 Precision Fermentation Oxygen Transfer 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.
