Electrochemical Ammonia Synthesis Patents: Leaders & Trends 2026
Electrochemical Ammonia Synthesis Patents: Who Leads and Where the Field Is Still Open
41.6% concentration at the top. The five leading assignees account for 128 of the 308 records in scope, but the tenth-ranked filer holds only 9 — a steep drop-off into a long tail. Filings rose from 13 in 2017 to a peak of 52 in 2023. The 2021-to-2024 comparison shows a 10% decline, but 2025 and 2026 figures are still filling in under normal publication lag, so treat the most recent two years as incomplete rather than as evidence of a downturn.

Common questions about electrochemical ammonia synthesis patents
Who holds the most patents in electrochemical ammonia synthesis?
The ranking in this dataset covers 93 assignees, and the leading one holds 40 of the 308 records in scope, well ahead of the fifth-ranked assignee at 14. The top five combined account for 41.6% of all records, but the gradient below that is steep: the tenth-ranked assignee holds only 9. That means the field has a genuine leader plus several active followers rather than a single dominant monopoly position, and most of the remaining assignees file only once or twice.
Is electrochemical ammonia synthesis patent activity growing or slowing down?
Filings rose fairly steadily from 13 in 2017 to a peak of 52 in 2023. Comparing 2021 to 2024 shows a 10% decline, which looks like a cooling trend on the surface. However, patent publication typically lags actual filing by around 18 months, so the 2025 and 2026 counts in any dataset are still incomplete and should not be read as proof the technology is losing momentum.
Which patent classes matter most for electrochemical ammonia synthesis?
C25B, covering electrolytic production of compounds, appears in 80.2% of the 308 records in scope and is by far the dominant class. B01J (catalysis, 21.4%) and C01C (ammonia and nitrogen compounds, 20.5%) follow at a distance, with H01M (batteries and cells, 16.2%) also present given the overlap with electrochemical cell hardware. Separation (B01D) and water treatment (C02F) classes are present but comparatively lightly claimed, at 8.1% and 5.8% respectively.
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 Electrochemical Ammonia Synthesis 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.
