Catalyst Deactivation Monitoring Patent Snapshot 2026
The patent corpus for catalyst deactivation monitoring is extremely small, with a single patent family in scope, dominated by academic filers rather than industrial incumbents. Activity is concentrated in Europe and China, with no measurable filing trend across the prior decade.
Academic filers dominate a nascent, thinly populated space
The corpus covers 1 patent family, with Università degli Studi di Salerno ranking first among applicants with 3 patent records, followed by Zhejiang University of Technology and SOL, each with 1 patent record.
The top five filers account for 100% of the ranked applicants visible in this query’ combined total, indicating an exceptionally concentrated and early-stage field with no diversified commercial player base yet established.

The visible position of academic institutions — one Italian university and one Chinese university — suggests the technology remains largely in pre-commercial research, with limited industrial filing activity observed.
The most recent period may be under-counted due to standard patent publication lags of 18–24 months; the apparent absence of recent filings should not be interpreted as confirmed inactivity. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
A single filing event in 2025 against a decade of inactivity
The annual trend and technology composition charts together reveal a field that has generated negligible filing volume over the observed window, with the lone data point appearing in 2025 and catalysis-process classes accounting for the bulk of IPC coverage.
Annual filing trend
Only one filing event is recorded across the entire 2017–2026 window, appearing in 2025. Given the 18–24 month publication lag, the 2025 and 2026 bins should be treated as potentially under-counted rather than representative of the full picture.

The IPC branch B01J (chemical/physical processes and catalysis) is the visible class with 5 patent records, followed by C01B (non-metallic elements and inorganic compounds) with 4 records, and C02F (water and wastewater treatment) with 1 record. The concentration in B01J reflects the core catalytic-process focus of the existing filings.

The present invention relates to the make of a heterogeneous gas-solid catalytic reactor operated in autothermic conditions, characterised by a flat temperature profile. This invention concurrently uses three actions to optimise the operation of the ATR reactor both in terms of energy and of catalytic activity: the adoption of a specifically formulated… (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.
Università degli Studi di Salerno
Salerno holds 3 patent records, all concentrated in B01J IPC classes covering chemical/physical processes and catalysis (sub-classes B01J 19, B01J 23, and B01J 35). As an academic institution, its filing strategy appears oriented toward protecting process-level innovations rather than commercial deployment. Applicant momentum data is not available in the current evidence set.
families: 3 recordsZhejiang University of Technology
Zhejiang University of Technology holds 1 patent record, with technology focus spanning B01J 23, B01J 35, and C02F 1 — the last sub-class extending into water and wastewater treatment, distinguishing its profile from Salerno’s purely catalytic focus. Applicant momentum data is not available in the current evidence set.
families: 1 recordFrequently asked questions
The current corpus contains 1 patent family in scope. This is a very small corpus, and the field as a distinct patenting category appears to be in an embryonic stage.
Università degli Studi di Salerno is the leading filer with 3 patent records, all concentrated in B01J IPC classes covering chemical and physical processes related to catalysis.
Europe (EPO) leads with 2 patent records, followed by China, Germany, and Denmark each with 1 patent record. No US filings are recorded in the current corpus.
B01J (chemical/physical processes and catalysis) is the visible IPC class with 5 patent records, reflecting the core process-chemistry focus of the existing filings.
No co-applicant pairs are identified in the current evidence. The absence of collaboration data may reflect the very small corpus size rather than a structural barrier to partnership in the field.
Not necessarily. Standard patent publication lags of 18–24 months mean that recent filings may not yet appear in the corpus, and the very thin density across all years may also reflect the narrow query scope rather than a complete absence of relevant research activity.

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.
