Amine Post Combustion Capture Patents: Leaders & Trends 2026
Amine-Based Post Combustion Capture Patents: Who Leads and What They Hold
Concentrated but not locked up. the top 5 assignees hold 25.5% of all 734 records in scope, and the top 10 hold 40.6% — a meaningful lead position with a long tail behind it. Filings rose from 23 in 2017 to a peak of 61 in 2024, including a +56% climb from 39 in 2021 to that 2024 peak. 2025 and 2026 figures (down to 6 by 2026) reflect publication lag rather than a real drop in filing activity.

Common questions about this landscape
Who holds the most patents in amine-based post combustion capture?
The leading assignee in this dataset holds 65 of the 734 records in scope, well ahead of the fifth-place assignee at 26 and tenth place at 20. The gap between first and fifth place is steep, but the drop from fifth to tenth is comparatively shallow, meaning the mid-tier of active filers is fairly tightly packed. Overall, the top 10 assignees combined account for 40.6% of all records, leaving the majority spread across a long tail of smaller filers.
Is patent filing in amine post combustion capture still growing?
Filing volume grew from 39 records in 2021 to a peak of 61 in 2024, a +56% increase over that span, which is the most reliable growth read available. Figures for 2025 and 2026 appear lower, but that reflects publication lag of roughly 18 months rather than an actual decline in filing activity, since recently filed applications have not all published yet. Anyone assessing momentum should treat 2024 as the latest complete year and be cautious about reading the two years after it as a downturn.
What technology areas dominate the patent claims in this field?
IPC subclass B01D, covering separation processes, appears in 77.9% of the 734 records, making the core absorption and stripping unit operation the most heavily claimed area by far. Supporting chemistry classes such as C01B (15.4%), C07C (9.0%) and C10L (8.3%) cover the gas stream and solvent composition side of the technology. Because a single record can carry multiple IPC codes, these shares add up to more than 100% and should be read as overlap, not a strict partition of the field.
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 Amine Based Post Combustion Capture covering 2015–2026, data cut-off 2026-07-31.
