Reverse Water Gas Shift and Syngas Conditioning Patents
Filings peaked in 2023 at 53 and the 2021→2024 complete-year span shows a 9% pullback, not a collapse — publication lag still understates 2025-26. Annual filings rose from 17 in 2017 to a peak of 53 in 2023. The complete-year comparison of 2021 (33) against 2024 (30) shows a 9% decline over that span — a real but modest pullback, not a downward trend, since 2025 and 2026 figures are still being filled in by the roughly 18-month publication lag.

Frequently asked questions
What is reverse water gas shift used for in patent filings?
Reverse water gas shift (RWGS) converts carbon dioxide and hydrogen into carbon monoxide and water, and patent filings in this space typically position it as the upstream step feeding Fischer-Tropsch synthesis or methanol production. Claims tend to focus on catalyst formulations that resist carbon formation, reactor designs that manage the endothermic heat load, and syngas ratio control downstream. This dataset of 496 records spans exactly that range, from catalyst chemistry through to conditioning and recycle steps.
Who are the leading patent filers in RWGS and syngas conditioning?
The ranking covers 100 assignees drawn from the full 496-record dataset, with the leader holding 29 records and a gradual taper down to 17 at tenth place. The top 5 combined account for 26.4% of all records and the top 10 for 43.5%, meaning well over half of the filings in this space come from outside the ranked leaders. The assignee base includes integrated oil and chemicals majors, an engineering licensor, and at least one university, rather than a single dominant player.
Is patent filing activity in this space growing or slowing?
Filings rose from 17 in 2017 to a peak of 53 in 2023, then the complete-year comparison between 2021 (33) and 2024 (30) shows a 9% decline over that span. That is a modest pullback rather than a sustained downturn, and because publication typically lags filing by around 18 months, the lower counts recorded for 2025 and 2026 are still incomplete and should not be read as evidence of a slowing field yet.
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 Reverse Water Gas Shift and Syngas Conditioning 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.
