Fischer Tropsch Efuels Patents: Top Companies & Filing Trends 2026
Fischer Tropsch synthesis patents for efuels: who leads and where claim space is still open
37.8% of the field sits with five assignees. 544 of 1,439 records in scope belong to the top five filers, with a longer tail of single- and low-count entrants behind them. Filings rose to a peak of 51 records in 2021, then declined to 30 by 2024 — a documented -41% over that three-year span. 2025 and 2026 figures (down to 3 by 2026) are not a real drop-off; publication lags filing by roughly 18 months, so the most recent two years are still filling in.

Common questions on Fischer Tropsch efuels patents
Who holds the most Fischer Tropsch synthesis patents for efuels?
The assignee ranking in this dataset covers 100 companies drawn from 1,439 records, and it is led by a single assignee holding 169 records. The top five combined hold 544 records, or 37.8% of the field, while the tenth-ranked assignee holds only 25 — showing a clear leader followed by a steep drop into a long tail of smaller filers. This concentration pattern is typical of a mature refining-adjacent technology where a handful of oil majors and specialist reactor developers built out core claims early.
Is Fischer Tropsch efuels patent activity growing or slowing down?
Filing activity rose to a peak of 51 records in 2021 and had fallen to 30 by 2024, a documented -41% decline over that three-year span. Numbers for 2025 and 2026 appear lower still, but that reflects the roughly 18-month lag between filing and publication rather than an actual continued slide — those years are still filling in. The fair read is a real cooling from the 2021 peak, not a field in freefall.
What technology areas dominate Fischer Tropsch efuels patents?
Hydrocarbon oil processing and refining (IPC class C10G) appears in 53.8% of the 1,439 records, making it the single most common classification. Acyclic and carbocyclic organic chemistry (C07C, 33.4%) and catalysis-related chemical processes (B01J, 31.1%) follow. Gasification and fuel gas purification classes each appear in roughly one in ten records, marking comparatively lighter claim density in those parts of the syngas-to-fuel chain.
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 Fischer Tropsch Synthesis for Efuels 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.
