Zeolite Catalyst Advanced Materials Patent Landscape 2026
Filing activity has cooled since its 2018 peak of 47. the midpoint year of 2022 sat at 28, and the trend has not recovered since — this is a mature claim space, not a growing one. Filings rose from 9 in 2017 to a peak of 47 in 2018, then settled to 28 by the 2022 midpoint. There is no second wave visible in the data through the (partial) most recent year — treat any apparent tail-off in the last one to two years as publication lag rather than a real drop.

Common questions on this landscape
What counts as a hierarchical zeolite in patent claims?
In this corpus, hierarchical zeolite claims describe frameworks engineered to have more than one pore-size regime — typically combining the standard microporous zeolite structure with introduced mesopores or macropores to improve diffusion and reduce coking. Claims usually specify either a synthesis route (templated growth, post-synthetic treatment) or a resulting pore-size distribution as the point of novelty. Because this is the dominant claim style in the dataset, a new filing needs to distinguish itself on the specific pore-generation method, not just the presence of hierarchy.
Why did zeolite catalyst filings peak in 2018 and decline afterward?
The trend data shows filings rising from 9 in 2017 to 47 in 2018, then falling to 28 by 2022 with no recovery visible since. This pattern is consistent with an early land-grab on core composite and framework-modification claims, followed by later filers finding less open claim space. Recent-year figures are also understated by roughly 18 months of publication lag, so some of the apparent decline in the last year or two will correct upward as pending applications publish.
Who are the leading assignees in metal-zeolite composite patents?
Co-assignee data points to a Saudi-anchored cluster: Saudi Arabian Oil Company (Saudi Aramco) pairs separately with JGC Catalysts and Chemicals Ltd., King Abdullah University of Science and Technology (KAUST) and a Japan-based petroleum research cooperative, and those three relationships are the strongest co-filing pairs in the dataset. Saudi Aramco Services Company and PTT Global Chemical Public Company Limited also appear among the tracked assignees. Nearly all of the leading names show zero filings and -100% year-on-year momentum in the latest tracked year, though this is partly a publication-lag effect.
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.
