Data to 2026-07-31

Enzyme Production Fermentation Oxygen Transfer Patents

Filing is concentrated at the top. the five most active assignees hold 32.5% of all 366 records in scope, and the top ten hold 47.0%. Filings rose to a peak of 12 in 2021, the highest year in the series. From 2021 to 2024 — the most recent year that can be treated as complete — filings fell from 12 to 8, a -33% change. Years after 2024 are still filling in as publications catch up with filing dates, so they should not be read as continued decline.

Frequently Asked

Questions practitioners ask about this field

Who are the leading patent filers in enzyme production fermentation oxygen transfer?+

Filing in this field is concentrated at the top: the five most active assignees together account for 32.5% of the 366 records in scope, and the ten most active account for 47.0%. That leaves a long tail of single- or few-filing entrants outside the ranked leaders. Anyone entering this space should expect to run freedom-to-operate checks primarily against a small number of established filers, since they hold a disproportionate share of the filed art relative to their number.

Is patent filing in this field growing or slowing down?+

Filings peaked in 2021 at 12 for the year and fell to 8 by 2024, a -33% change over that three-year span — the most recent period that can be treated as complete. Data for 2025 and 2026 is still incomplete because publication typically lags filing by around 18 months, so those later years understate true filing activity and should not be read as a continued decline. A fair reading is that filing has eased off its 2021 peak but has not necessarily stopped.

Which patent classes matter most for enzyme fermentation and oxygen transfer claims?+

C12N (microorganisms and genetic engineering) and C12P (fermentation and enzymatic synthesis) are the two dominant classes, appearing on 64.5% and 62.8% of the 366 records in scope respectively — meaning most filings claim either the host organism or the production process itself. C12M, covering bioreactors and enzyme apparatus, appears on 27.3% of records, showing that hardware and vessel-level claims are a secondary but still substantial layer. Because a single record can carry multiple IPC codes, these shares add up to more than 100% and should not be read as mutually exclusive categories.

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 Enzyme Production 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.
