Catalyst Batch / Activity QC Patent Snapshot 2026
The catalyst batch and activity QC patent space is a small, highly concentrated field anchored by a single dominant filer, General Electric Co, with filings clustered primarily in Europe via the EPO. Activity is sparse and episodic, signalling an early-stage niche with substantial room for new entrants to establish IP positions.
General Electric Co leads a heavily concentrated field
General Electric Co holds the top position with 7 patent records, placing it well ahead of all other filers. The National University of Singapore ranks second with 3 patent records, and all remaining applicants each hold a single patent record.
The top five filers together account for 87% of the combined total across the ranked applicants visible in this query, indicating an unusually narrow competitive base. The gap between the leader and the second-tier filers is significant, with no credible challenger cluster formed to date.

General Electric Co’s lead, concentrated in chemical/physical processes and catalysis (B01J) alongside coating and surface deposition (C23C), reflects a deliberate focus on coated-article and hydrocarbon-fluid applications rather than broad QC instrumentation. This focus leaves adjacent analytical and process-monitoring routes largely open.
Patent records published in roughly the last 18–24 months are subject to publication lag and likely undercount true recent activity; the 2025 and 2026 figures should be treated as provisional. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
Episodic filing bursts and a catalysis-dominated technology mix
Annual filing activity is sparse and irregular, with a notable burst in 2022 followed by renewed activity signalled in 2025, though that recent figure is subject to publication lag. The technology composition is dominated by B01J (chemical/physical processes and catalysis) but spans a wide secondary mix including coatings, gas turbines, and heat exchangers.
Annual filing trend
A single filing appeared in 2017, a cluster of four arrived in 2022, and two provisional records are visible in 2025; intervening years show no activity. Given publication lag, the 2025 figure is likely undercounted and should not be interpreted as a plateau.

B01J (chemical/physical processes and catalysis) is the visible branch by a wide margin, reflecting the core QC subject matter. Secondary clusters in C23C (coatings), F02C (gas-turbine plants), and F28F (heat-exchanger details) point to application domains — turbine and combustion systems — rather than standalone analytical methods.

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. Treat this section as citation context, not as a curated list of the most topic-specific patents. 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.
General Electric Co
General Electric Co holds 7 patent records, making it the sole visible filer in this space. Its technology emphasis spans B01J 19 and B01J 37 (chemical and physical process methods) and C23C 16 (chemical vapour deposition and coating), consistent with its portfolio of coated-article patents for hot hydrocarbon fluid applications. The most-cited patent in the corpus — cited 57 times — is a coated-article patent attributable to this lineage. No momentum trend data is available for General Electric Co, indicating it is an established rather than newly active filer.
patent records: 7National University of Singapore
The National University of Singapore holds 3 patent records and is classified as a new entrant, with all of its activity appearing in the recent window. Its technology focus centres on B01J 35 (catalyst form and structure), B01J 19, and B01J 32 (regeneration of catalysts), indicating an interest in fundamental catalyst characterisation and activity restoration rather than applied coating systems. As an academic institution, it is likely to be a source of licensing opportunities rather than a direct commercial competitor.
patent records: 3Frequently asked questions
The corpus analysed contains 7 patent families in scope. This is a small and specialised field, and the low total underscores that systematic IP coverage of catalyst batch and activity QC as a distinct subject area is still nascent.
General Electric Co leads with 7 patent records, well ahead of the National University of Singapore in second place with 3 patent records. All other applicants hold a single patent record each.
Europe via the EPO is the primary filing destination with 6 patent records, followed by WIPO (PCT) at 4, Canada and China each at 3, and the United States at 2. India and Malaysia each have 1 patent record. The relatively low US count compared to EPO is notable.
B01J (chemical and physical processes and catalysis) is the visible branch by a wide margin. Secondary branches include C23C (coating and surface deposition), F02C (gas-turbine plants), and F28F (heat-exchanger details), reflecting turbine and combustion-system application contexts.
Co-filing is limited to a cluster of three Chinese organisations — Hunan Xisi Ecology Technology, Hunan Landscape Construction, and Hunan Engineering Polytechnic — which have filed jointly with each other. No international or cross-sector co-filing is evident in the evidence.
C10G (hydrocarbon oils and refining) and G01N (material analysis and testing) stand out as under-served relative to the subject matter implied by catalyst activity QC. G01N in particular — the natural home for analytical and testing methods — appears only once, suggesting that analytical-method claim framing is largely unexplored in this corpus.

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.
