CO2 Utilization in Materials Patents: Top Companies & Trends 2026
Carbon Dioxide Utilization in Materials: Patents, Leaders and Filing Trends
Filings surged 132% from 2021 to 2024, climbing from 37 to 86 records in the peak year, before the newest years understate activity due to publication lag. Annual filings rose from 3 records in 2017 to a peak of 86 in 2024, a +132% increase from 2021's 37 filings to that 2024 peak. 2025 and 2026 figures (15 in 2026) are still filling in as publications catch up with filing dates.

Common questions about this landscape
Who holds the most patents in carbon dioxide utilization for materials?
The leading assignee in this dataset holds 30 of the 380 records in scope, ahead of a fifth-place holder at 20 records. The top 5 assignees combined account for 31.3% of all records, and the top 10 extend that to 46.8%, with the remainder spread across a ranking of 100 companies. That pattern points to a concentrated top tier followed by a long tail of smaller filers, rather than a single dominant monopoly.
Is patent filing in this field growing or slowing down?
Filing volume grew sharply, rising +132% from 37 records in 2021 to a peak of 86 in 2024. Years after 2024 show lower counts, but that reflects publication lag — patent applications typically publish around 18 months after filing, so 2025 and 2026 figures are still incomplete rather than evidence of a real slowdown. The 2024 peak is the most reliable recent-year figure available.
Which patent classes dominate carbon dioxide utilization in materials?
C04B, covering ceramics, cement and refractories, is the largest class at 27.6% of the 380 records, reflecting the weight of carbonation curing of concrete in this field. B01D separation processes and C01F alkaline-earth compounds follow closely at 18.4% and 18.2% respectively. Because a single record can carry several IPC classes, these shares add up to more than 100% and should be read as overlap indicators, not a strict breakdown.
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.
