MOF CO2 Adsorption Patents: Top Companies & Filing Trends 2026
MOF Carbon-Dioxide Adsorption Patents: Who Is Filing and Where the Field Is Still Open
Filing is still climbing. 2021→2024 filings rose 16% (1,967 to 2,287), with 2023 the peak year so far at 2,362 — the field has not plateaued. Annual filings grew from 941 in 2017 to a peak of 2,362 in 2023, and the most recent complete three-year span (2021-2024) shows +16% growth from 1,967 to 2,287 filings. Years after 2024 are shown but understated because of publication lag, and should not be read as a slowdown.

Common questions about this landscape
Who are the leading companies filing MOF carbon-dioxide adsorption patents?
The ranking covers 100 companies, and no single one dominates: the leading assignee holds 496 records against a total of 24,103, and the top 5 combined reach only 6.9% of all records in scope. Names appearing near the top include BASF, University of California, ExxonMobil’s technology and engineering arm, CNRS and King Abdullah University of Science and Technology, spanning both chemical majors and research universities. This spread means competitive positioning depends more on which specific sub-application a filer targets than on out-filing a dominant incumbent.
Is the MOF CO2 adsorption patent field growing or slowing down?
It is growing. Complete-year data shows filings rising from 1,967 in 2021 to 2,287 in 2024, a 16% increase, with 2023 the peak year recorded so far at 2,362. Figures for 2025 and 2026 appear lower in raw counts, but that reflects the roughly 18-month lag between filing and publication rather than an actual drop in activity, so those years should not yet be read as a slowdown.
Which patent classes cover the most MOF CO2 adsorption claims?
B01J, covering chemical and physical processes including catalysis, accounts for 28.8% of the 24,103 records, and B01D, covering separation processes such as filtration, accounts for 22.4%. C08G (condensation polymers) follows at 14.1%, with organo-metallic compounds (C07F), inorganic compounds (C01B) and battery-related H01M each in the 6-8% range. Because records can carry multiple classes, these figures describe coverage rather than a strict partition of the corpus.
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.
