Catalysis Techno-Economic Patent Snapshot 2026
The catalysis techno-economic patent space is a concentrated, emerging field where a small number of applicants — led by Thrunnel Ltd Oy — account for the majority of documented activity. The field is still expanding on a multi-year basis, though annual volume has eased from its 2018 peak and recent years remain undercounted due to publication lag.
A highly concentrated field dominated by two anchor filers
Thrunnel Ltd Oy leads the applicant ranking with 9 patent records, followed by the Council of Scientific and Industrial Research with 6. The top five filers collectively account for 59% of the ranked applicants visible in this query’ combined total, signaling a tightly held competitive position.
The gap between the first-ranked applicant and the rest of the field is substantial. Individual inventors and small research institutions occupy the mid-tier, with no second corporate entity yet approaching the leader’s scale.

Thrunnel Ltd Oy’s lead — built primarily on electrolytic production of compounds (C25B) and core catalysis classes (B01J) — suggests a deliberate technology strategy rather than opportunistic filing. This concentration leaves meaningful space for challengers who can differentiate on process chemistry or application domain.
The most recent 18–24 months of data should be treated as preliminary; publication lag means actual recent filing volume is likely higher than the trend currently shows. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
A 2018 surge defines the baseline; B01J and C25B dominate the technology mix
The filing trend reveals a pronounced burst of activity in 2018, followed by a return to low single-digit annual volumes. The technology composition shows that chemical and physical processes in catalysis (B01J) and electrolytic production of compounds (C25B) together anchor the field.
Annual filing trend
The 2018 spike — 20 patent records in a single year — dwarfs every other year in the dataset and establishes the historical high-water mark. Annual volume since 2019 has remained low, though the most recent years (2024–2026) are understated by publication lag and should not be read as a sustained plateau.

B01J (chemical/physical processes and catalysis) and C25B (electrolytic production of compounds) together represent the visible technical branches. C07C (acyclic and carbocyclic compounds) is a significant secondary branch, while C10L, C07B, C07F, C11C, and H01G each appear at much lower frequency, marking the adjacent territory with the least incumbent coverage.

The process of preparing a chromium-free heterogeneous catalyst based on iron, enhanced with K2O for the high-temperature water-gas shift reaction with the ability to suppress methane formation, aims to replace the commercial catalyst (Fe-Cr) used in the high-temperature water-gas shift reaction. The commercial catalyst contains Cr6+ which is carcinogenic… (excerpt from the patent abstract)

Some patent titles may be shown in their original, non-English language where an accurate translation could not be guaranteed.
Assignee snapshot from the current evidence set
The applicants below are visible in this query result. Because the evidence set is relatively small, read this section as a directional snapshot rather than a full competitive ranking.
Thrunnel Ltd Oy
Thrunnel Ltd Oy holds 9 patent records and concentrates its portfolio on C25B 3 (electrolytic production of compounds), B01J 29, and B01J 35 (chemical/physical processes and catalysis). The applicant also has a documented co-filing relationship with ABO-Hashema Khaled A H (3 joint records), suggesting a partnership-augmented strategy. No momentum data beyond its current rank is available in evidence.
patent records: 9Council of Scientific and Industrial Research
The Council of Scientific and Industrial Research holds 6 patent records and focuses on C07D 301 (heterocyclic compounds) and C12N 9 (microorganisms and genetic engineering), distinguishing it from the leader’s electrolytic focus. As a major Indian public research body, its trajectory reflects institutional research priorities rather than commercial product cycles.
patent records: 6Frequently asked questions
The dataset covers 31 patent families in scope. This is a small, specialized corpus, which means individual filers and single patents carry outsized weight in any competitive analysis.
Thrunnel Ltd Oy leads with 9 patent records, concentrating on electrolytic production of compounds (C25B 3) and chemical/physical catalysis processes (B01J 29 and B01J 35).
The field is classified as Growth: recent three-year filing volume sits above the prior three-year window. However, annual volume has eased from its 2018 peak, so growth is multi-year in aggregate rather than accelerating annually.
India leads with 11 patent records, followed by the United States with 6 and Israel with 4. The distribution reflects the institutional base of the major applicants, several of whom are Indian research organizations or India-linked inventors.
One co-filing relationship is documented: ABO-Hashema Khaled A H and Thrunnel Ltd Oy have 3 joint records. No other co-filing pairs appear in the evidence, suggesting the broader ecosystem has not yet formed a collaborative network.
C10L (fuels and firelighters), C07B (general organic chemistry methods), C07F (organo-metallic compounds), C11C (fatty acids and candles), and H01G (capacitors) each appear in 3 or fewer patent records, making them the sparsest classified branches adjacent to the visible B01J and C25B core.

Patent data carries inherent limitations: recent filings (typically the most recent 18–24 months) are under-counted due to standard publication lag; counts may be reported at either a patent-family or a patent-record basis and are not always directly comparable; classification, applicant-name, and citation data may contain errors, duplicates, or omissions; and the underlying search query defines and constrains the scope shown. As a result, the analysis may be incomplete or inaccurate and may not reflect the full technology landscape.
