Gas Fermentation & C1 Feedstock Patents: Leaders & Trends 2026
Gas Fermentation and C1 Feedstock Patents
41.4% concentration. The top five assignees hold 218 of the 527 records in scope — a field where a handful of players occupy most of the claim space. Filings rose from 32 in 2017 to a peak of 46 in 2022, then settled back — 2021 and 2024 both sit at 27, a 0% change across that span. Treat the final one to two years as undercounted given publication lag rather than as a genuine drop.

Common questions on gas fermentation patents
Who holds the most patents in gas fermentation and C1 feedstock conversion?
The leading assignee in this dataset holds 51 of the 527 records in scope, with the top five combined accounting for 218 records, 41.4% of the field. That concentration steepens further at the top ten, which reach 64.5% of all records. Names associated with syngas fermentation commercialization, including LanzaTech-affiliated entities and Ineos Bio, appear repeatedly across the ranked list, alongside academic and newer entrant filers with smaller counts.
Is gas fermentation patent filing still growing?
Filing volume peaked at 46 in 2022 and has since settled, with 2021 and 2024 both recording 27 filings — a 0% change across that span. The 2025 and 2026 figures in the raw trend appear lower still, but that reflects the roughly 18-month lag between filing and publication rather than an actual drop in activity. The fair read is a plateau after a growth phase, not a decline.
What technology areas dominate gas fermentation patents?
Fermentation and enzymatic synthesis claims, IPC class C12P, appear on 69.1% of the 527 records, making it the dominant technology area by a wide margin. Microorganism and genetic engineering claims (C12N) and bioreactor apparatus claims (C12M) each sit above a quarter of records, showing that organism engineering and reactor hardware are filed about as heavily as each other. Electrolytic production claims (C25B) at 19.0% point to a meaningful electro-fermentation overlap with the core biological process claims.
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 Fermentation and C1 Feedstocks 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.
