Catalytic Process Safety Patent Snapshot 2026
The catalytic process safety patent space is highly concentrated, with CSIRO (Commonwealth Scientific and Industrial Research Organisation) and Air Products & Chemicals jointly leading the field and together accounting for the bulk of the top filers’ activity. Filing activity has been sparse across the observed window, with a modest cluster appearing in 2024, though recent periods remain subject to publication lag.
A highly concentrated field co-led by CSIRO and Air Products & Chemicals
The top two applicants — CSIRO and Air Products & Chemicals — are tied at the head of the ranking, each with 14 patent records, followed by General Motors LLC at 7 patent records. These three organizations form a clear first tier with no close challengers.
The top five filers account for 93% of the combined total among the ranked applicants visible in this query, indicating extreme concentration. Beyond the top three, the remaining ranked applicants each hold a single patent record, confirming a steep drop-off into a long tail of one-off participants.

The dominance of CSIRO and Air Products & Chemicals signals that catalytic reactor design and chemical process safety innovation is being driven primarily by an industrial research organization and a major industrial gas company, both with deep technical infrastructure in continuous-flow and heterogeneous catalysis.
Filings from approximately the last 18 to 24 months are likely under-counted due to standard patent publication lag and should not be interpreted as reflecting the true current pace of activity. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
Sparse activity through most of the decade, with a notable 2024 cluster across a broad IPC mix
The annual filing trend and technology composition charts together reveal an intermittent filing pattern dominated by a handful of IPC branches, with reactor catalysis and mixing technologies accounting for the majority of patent records.
Annual filing trend
Filing activity was effectively absent from 2017 through 2023, with a single record appearing in 2018 and no further activity until a cluster of four records emerged in 2024. The 2025 figure carries one record, but given publication lag, the actual pace of current activity cannot be confirmed from these counts alone.

B01J (chemical and physical processes and catalysis) is the visible branch, followed by B01F (mixing and stirring) and C07C (acyclic and carbocyclic compounds). Combustion-related branches — F23C, F23D, F23K — and pressure vessel technology (F17C) each hold smaller but equal shares, pointing to secondary threads around safe handling of reactive gases and combustion management.

Ranked by total forward citations. Citation counts favour older and broadly cited patent families, and broad or adjacent patents may appear when they match the search scope.

What the competitive structure implies for R&D investment decisions
Three structural features stand out for R&D planning: the extreme concentration among top filers, the sparse but suddenly active 2024 cohort, and the presence of adjacent combustion and pressure-vessel branches that remain thinly covered.
Life-cycle stage: evidence pending
The evidence base does not supply a computed life-cycle stage for this topic. What is observable is a very low cumulative volume of 6 patent families spread across a decade, with near-zero activity for six consecutive years before a 2024 uptick. This pattern is consistent with either an early-stage or niche-specialist field rather than a mature, high-volume one, but a definitive stage classification requires a larger corpus.
Early / Niche signalTwo co-leaders hold the field; no mid-tier challenger yet visible
CSIRO and Air Products & Chemicals are tied at the top with 14 patent records each, and General Motors LLC follows at 7. All remaining ranked applicants hold a single record. The top five filers’ 93% share of the ranked applicants visible in this query’ combined total leaves little room for an unrecognized incumbent — any entrant without a focused filing program will face an immediate visibility gap against these two leaders.
High concentrationLimited co-filing observed, centered on Toxfree Systems and Sustaine Energy
Three co-applicant pairs are recorded in the evidence: Toxfree Systems Inc. with Sustaine Energy Pty Ltd, and Struan Glen Robertson with each of those two entities, all at a co-filing count of one. This suggests collaboration in this space is nascent and project-specific rather than systematic. Neither of the two visible applicants appears in any recorded co-filing pair, indicating the leaders operate independently.
Low collaborationUnited States is the primary protection jurisdiction, with EPO and Australia as secondary markets
The United States leads with 12 patent records, followed by Europe via the EPO with 9 and Australia with 5. WIPO PCT filings number 4, with Canada, India, Austria, China, Germany, Japan, and Singapore each holding 1 to 2 records. The prominence of Australia aligns with CSIRO’s national mandate. The relatively thin PCT and non-US filing count suggests that many applicants are not yet pursuing broad global protection in this niche.

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.
Commonwealth Scientific and Industrial Research Organisation
CSIRO holds 14 patent records and is characterized by a trifecta of focus areas: chemical and physical processes and catalysis (B01J 19), and two mixing and stirring sub-classes (B01F 13 and B01F 5), reflecting a strong interest in continuous-flow reactor safety and catalyst-agitation integration. Its momentum is flagged as a new entrant in the most recent period, with 4 recent filings, suggesting an active and accelerating program from a previously low base.
patent records: 14Air Products and Chemicals, Inc.
Air Products & Chemicals also holds 14 patent records and concentrates on catalysis process design (B01J 19 and B01J 8) alongside general organic chemistry methods (C07B 61), pointing to process chemistry safety for industrial gas and chemical synthesis applications. No momentum trend is separately recorded for this applicant in the evidence, but its tied rank with CSIRO and its strong focus on reactor bed and organic chemistry safety positions it as a co-leader with a distinct industrial chemistry orientation.
patent records: 14Frequently asked questions
The evidence covers 6 patent families in scope. This is a small corpus, consistent with a niche or early-stage field rather than a high-volume technology area.
CSIRO (Commonwealth Scientific and Industrial Research Organisation) and Air Products and Chemicals, Inc. are co-leaders, each with 14 patent records. General Motors LLC follows with 7 patent records. All remaining ranked applicants hold a single record each.
The United States leads with 12 patent records, followed by Europe via the EPO with 9 records and Australia with 5 records. Australia’s prominence reflects CSIRO’s national base of operations.
B01J (chemical and physical processes and catalysis) is the visible branch, followed by B01F (mixing and stirring) and C07C (acyclic and carbocyclic compounds). Combustion-related classes and pressure vessel technology form a secondary cluster.
Collaboration is limited. Three co-filing pairs are recorded, all involving Toxfree Systems Inc., Sustaine Energy Pty Ltd, and Struan Glen Robertson, each at a co-filing count of one. The two visible applicants — CSIRO and Air Products & Chemicals — do not appear in any recorded co-filing arrangement.
Pressure vessel and gas storage technology (F17C), combustion apparatus (F23C), burners (F23D), and fuel feeding to furnaces (F23K) each hold only 7 patent records and a 5% share of the corpus, making them the most sparsely covered branches adjacent to the core catalysis cluster. Non-metallic elements and inorganic compounds (C01B) is similarly thin at 5 records.

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.
