Zeolite Catalyst Carbon Capture Patent Landscape 2026
Zeolite Catalyst Carbon Capture Patent Landscape 2026
Filing has already peaked. 2022 (42 families) is the high point in the series; the run rate has since eased back toward levels last seen before 2020. Filings rose from 15 in 2017 to a peak of 42 in 2022, then eased down to 7 by 2026 — a partial year. Reading the midpoint against the peak, growth in this field is flat to declining rather than accelerating, which argues against treating zeolite CO2 sorbent chemistry as an emerging space.

Common questions about this landscape
Are zeolite catalysts still being actively patented for carbon capture?
Filing volume peaked at 42 families in 2022 and has declined since, reaching 7 by 2026, though that final year is still partial because publication lags filing by around 18 months. Read together, the trend is flat-to-declining rather than growing, so new activity is real but no longer accelerating. Anyone entering the space should expect to be filing into a mature, well-mapped claim base rather than a fresh one.
Which patent classes matter most for zeolite CO2 capture filings?
B01D (separation processes, 350 of 398 records) and B01J (catalytic and adsorption processes, 311 records) carry almost all of the claim density, with C01B (inorganic compounds, 159 records) close behind. C10L, C07C, C10G, F25J and G01N appear only in single or low double digits, marking them as thin rather than crowded. A filing strategy built around B01D/B01J alone will be competing in the most contested part of the landscape.
Who are the leading assignees in zeolite carbon capture patents, and are they still active?
The named leading assignees — including ExxonMobil Research and Engineering Company, Asahi Kasei Corporation, ExxonMobil Upstream Research Company, Chevron U.S.A. Inc., Georgia Tech Research Corporation and Ceca S.A. — each recorded zero filings in the most recent tracked year. Their position in the ranking reflects historical volume built over the 2015–2022 window rather than current filing behaviour. That gap is worth watching, since renewed activity from any of them would be a strong signal that the plateau is ending.
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 Zeolite Catalyst Carbon Capture 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.
