Porous Materials & MOFs Patents: Leaders, Trends & White Space 2026
- Filing is not concentrated at the top. the ranked leader holds 131 records and the top 5 combined account for just 9.1% of all 6,371 records in scope — this is a fragmented field, not a two-player race.
- Implants and batteries share the claim space with separation and sterilisation. A61F implants sit at 12.3% of records almost level with B01J catalysis at 12.5%, while H01M batteries and B01D separation each clear 9-10%, showing porous-material claims spread across at least four distinct application industries.
- Filing activity has pulled back from its 2021 peak. the peak year was 2021 at 348 records, falling 24% to 266 by 2024 — the last year the dataset treats as complete before the usual 18-month publication lag understates 2025-2026.
Filing growth compares 2021 (348 records) with 2024 (266) — a three-year span. 2024 is the most recent year we treat as complete: publication lags filing by roughly 18 months, so 2025 onwards are still filling in and any growth rate that ends there would understate the field. Top-5 share is the combined record count of the five largest assignees divided by all 6,371 records in scope (CR5), not by the ranked leaders only.
What the porous materials and MOF patent record shows
Metal-organic frameworks and other engineered porous materials sit at the intersection of chemistry and manufacturing, which is why the patent record for this search spans 6,371 records across implants, batteries, filtration, catalysis and sterilisation rather than a single industry vertical. The IPC composition confirms this: B01J (catalysis and physical processes) and A61F (implants and prostheses) each cover roughly an eighth of all records, with battery-related H01M and separation-related B01D close behind. No single application has captured the technology.
Filing rose steadily from 2017 through a peak in 2021, then eased back — a pattern consistent with an early wave of foundational MOF-synthesis and characterisation claims giving way to more selective, application-specific filing as commercial routes narrowed. Because publication lags filing by roughly 18 months, the most recent one to two years in any chart will always look lighter than they eventually turn out to be.

Filing trends and technology composition
Two views of the same 6,371-record dataset: how filing volume has moved year on year, and how records distribute across IPC subclasses. Both use all records in scope as the denominator, and a single record can carry more than one IPC class.
A 2021 peak followed by a pullback
Filing climbed from 216 records in 2017 to a peak of 348 in 2021, then declined 24% to 266 by 2024 — the last year this dataset treats as complete. Readings for 2025 and 2026 are still filling in under the usual publication lag and should not be read as a continued decline.
Claims spread across four application clusters
B01J (catalysis) and A61F (implants) each account for roughly one in eight records, with B01D (separation), A61L (sterilising), H01M (batteries) and C01B (inorganic compounds) all clearing 6% or more — evidence that porous-material claims are being filed against multiple end uses rather than one dominant application.
Shares are the percentage of the 6,371 records in scope. A patent can carry several IPC classes, so the shares add up to more than 100%.

System and method for selecting bi-metallic metal organic framework based on predicted properties
Filed by Accenture Global Solutions in March 2026, this application describes generating candidate bi-metallic MOF structures from desired metal types and linker functionality, extracting atomic features in machine-readable form, and predicting material properties for those candidates before synthesis.The filing date sits at the very edge of the dataset's coverage window, so its citation record is not yet established.

Four read-outs from the dataset that matter more for strategy than the raw counts alone.
No single assignee controls the field
The ranked leader holds 131 records against a total of 6,371, and the top 5 combined reach only 9.1% of all records in scope. That is a long tail of single- and few-filing entrants rather than a market gated by two or three incumbents.
Past the initial filing wave
Filing peaked in 2021 at 348 records and had fallen to 266 by 2024, the last complete year in scope. That reads as consolidation around narrower, more commercially targeted claims rather than an expanding land grab.
Catalysis and implants run neck and neck
B01J (catalysis and physical processes) and A61F (implants and prostheses) are almost tied at the top of the IPC composition, with battery and separation classes not far behind. Filing strategy in this field has to account for at least four application communities, not one.
US anchors filing, PCT keeps options open
The United States receives the largest single share of filings, with the EPO second and WIPO's PCT route third ahead of Canada, Australia and India. A sizeable PCT volume signals that many applicants are still deciding where to pursue national protection.
Eureka can read the same corpus for gaps instead of for coverage: under-claimed branches adjacent to porous materials & mofs patent landscape, with the prior art for and against each one.
Who is filing, and where the gaps sit
The ranking covers 100 companies returned by the data endpoint — a long tail, not a shortlist of dominant incumbents. Momentum in the most recent year is thin across almost every name at the top, which is expected given publication lag rather than a sign that filing has stopped.
A fragmented leaderboard
The leader's 131 records and fifth place's 104 sit well below what would be needed to dominate a 6,371-record field. Tenth place, at 77, is still filing at meaningful volume, which means competitive monitoring has to extend beyond the first five names.
A small number of tight partnerships
Only ten co-assignee pairs appear in the dataset, but the strongest ones are dense: one industrial-research pairing and two building-materials pairings each recur dozens of times, suggesting long-running joint development programmes rather than one-off co-filings.
Recent-year counts are thin across the board
Even assignees with substantial historical portfolios show only zero or one record in the most recent year. That is consistent with an 18-month publication lag pulling down every recent-year count, not with the leaders having stepped back from the technology.
| Assignee | Recent year | YoY |
|---|---|---|
| Procter & Gamble | 1 | — |
| Aspen Aerogels, Inc. | 1 | -67% |
| The Regents of the University of California | 0 | — |
| Saudi Arabian Oil Co. (Saudi Aramco) | 0 | — |

Where to take this next
The dataset points to specific follow-up questions rather than a single conclusion.
Track the application-specific split
Because B01J, A61F, H01M and B01D each carry meaningful share, a useful next step is separating implant-focused filings from battery- and separation-focused ones to see whether the same assignees cross application boundaries or stay specialised.

The apparent pullback from the 2021 peak needs re-checking once 2025 and 2026 filings finish publishing; treat any current read on those years as provisional.

The recurring co-assignee pairs suggest established joint-development relationships; checking whether these extend to licensing or supply agreements would sharpen freedom-to-operate analysis.

Within this dataset the ranked leader holds 131 records out of 6,371 total, with the top 5 assignees combined accounting for only 9.1% of all records. That means no single company controls the field; the ranking runs to 100 companies and includes a substantial long tail of firms with just a handful of filings each. Practical competitive monitoring in this space should track at least the top ten, not just the top one or two names.
Filing rose from 216 records in 2017 to a peak of 348 in 2021, then fell 24% to 266 by 2024, the last year in the dataset treated as complete. That is a genuine pullback from the peak, not a data artefact. Figures for 2025 and 2026 will look lower still, but that reflects the roughly 18-month lag between filing and publication rather than a real drop in activity.
The IPC composition shows filings concentrated in catalysis and physical processes (B01J, 12.5% of records), implants and prostheses (A61F, 12.3%), separation processes such as filtration (B01D, 10.8%), sterilising and disinfecting (A61L, 9.6%) and batteries and fuel cells (H01M, 9.5%). Because a single patent can carry multiple IPC classes, these shares overlap rather than sum to 100%. This spread indicates the underlying materials science is being commercialised across several distinct industries at once, not funnelled into one dominant use.
Lower-density branches inside this dataset include property-prediction workflows for candidate MOF structures, bi-metallic linker functionalisation, and characterisation-data pipelines that connect synthesis conditions to measured material properties. These sit adjacent to the heavily filed implant, battery and separation classes but carry less claim density themselves. A first claim there should tie a specific synthesis or selection method to a measurable property outcome rather than claiming a material composition broadly.
The United States receives the largest share of filings at 2,352, followed by the European Patent Office at 1,113 and the WIPO PCT route at 824, with Canada, Australia and India each in the low hundreds. The sizeable PCT volume suggests many applicants file internationally before committing to specific national phases. Firms assessing freedom to operate should treat the US and EPO as the two jurisdictions with the deepest prior art to search first.
