Catalytic Reactor Control Patent Snapshot 2026
The catalytic reactor control patent space is a small, highly concentrated field dominated by Commonwealth Scientific and Industrial Research Organisation (CSIRO), which alone accounts for the largest block of activity among the top ranked filers. Filing activity was sparse through 2019–2021 but rebounded visibly from 2022 onward, with several new entrants entering the ranking in the most recent period.
CSIRO leads a tightly held, specialist field
Commonwealth Scientific and Industrial Research Organisation (CSIRO) sits at the top of the applicant ranking, followed by Uhde GmbH in second place and Lydian Labs Inc and University of Bath tied in third. The top five filers collectively hold 66% of the combined total across the ranked applicants visible in this query, signaling a highly concentrated visible assignee structure.
There is a notable tier gap between the first-ranked applicant and the rest of the field. Below the top two, activity drops to single-digit patent record counts, and most ranked applicants hold only one or two records, indicating that participation is broad but shallow beyond the leading pair.

CSIRO’s sustained lead, anchored in chemical and physical process catalysis as well as mixing and stirring technology, suggests it has built a defensible technical position. Challengers entering in the most recent period — including Lydian Labs Inc and Air Products and Chemicals Inc — are new entrants whose long-term trajectory remains to be established.
The most recent 18–24 months of data are subject to publication lag and should be treated as an undercount of actual filing activity; the 2025–2026 figures in particular do not yet reflect full filing volume. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
Activity rebounded after a dormant period; catalysis processes dominate the technology mix
Two charts tell the story of this field: an uneven filing timeline with a marked gap in the early 2020s followed by a recovery, and a technology distribution firmly anchored in the B01J catalysis and B01F mixing classes.
Annual filing trend
Annual filings were low but nonzero in 2017–2018, then fell to zero for three consecutive years (2019–2021), before recovering to two records per year in 2022 and 2023 and jumping to six in 2024. The 2025 and 2026 figures reflect publication lag and should not be read as a real decline; actual activity in those years is likely undercounted.

B01J (Chemical/physical processes and catalysis) is the visible class by a wide margin, reflecting the core subject matter. B01F (Mixing and stirring) is the second branch, consistent with the prominence of static mixer and continuous-flow reactor designs among top-cited patents. Lower-share branches — including C01B (inorganic compounds), C07C (acyclic compounds), and B05B (spraying and atomising) — point to specific application niches that remain comparatively sparse.

Static mixers for continuous flow catalytic reactors
The present disclosure relates to catalytic static mixers comprising catalytic material. The static mixers can be configured for use with continuous flow chemical reactors, for example tubular continuous flow chemical reactors for heterogeneous catalysis reactions. This disclosure also relates to processes for preparing static mixers. This disclosure also… (excerpt from the patent abstract)

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 leads with 12 patent records and concentrates its portfolio in B01J 19 (chemical and physical processes and catalysis) and B01F 13 and B01F 5 (mixing and stirring), consistent with its known expertise in continuous-flow and static-mixer reactor designs. Its momentum trend is marked as a new entrant in the most recent period, suggesting recent filings represent a renewed or expanded push rather than legacy volume alone.
patent records: 12Lydian Labs Inc
Lydian Labs Inc holds four patent records and is a new entrant, with all four records falling in the most recent filing window. Its technology focus sits in C01B 3 and C01B 32 (non-metallic elements and inorganic compounds) supplemented by B01J 19, distinguishing it from the mixing-and-stirring emphasis of the leader and pointing toward inorganic synthesis control as its primary application domain.
patent records: 4Frequently asked questions
The corpus covers 14 patent families in scope. The applicant ranking is measured at the patent-record level, so individual applicant counts reflect records rather than families.
Commonwealth Scientific and Industrial Research Organisation (CSIRO) is the top-ranked applicant with 12 patent records, placing it significantly ahead of the second-ranked Uhde GmbH at six records.
The United States is the lead filing office with 11 patent records. Australia, Canada, Europe (EPO), and WIPO (PCT) each carry five records, reflecting both CSIRO’s home base and applicants’ use of the PCT route for multi-jurisdiction coverage.
B01J (Chemical/physical processes and catalysis) is the visible class by a wide margin. B01F (Mixing and stirring) is the second-largest class, consistent with the prominence of static mixer and continuous-flow reactor designs among the most-cited patents in the corpus.
Three co-filing pairs are evidenced: Uhde GmbH with Evonik Operations GmbH (two joint records), Uhde GmbH with Degussa AG (two joint records), and Kolaczkowski Stanislaw Tadeusz with University of Bath (two joint records). No co-filings involving the field leader CSIRO are evidenced.
Four applicants are identified as new entrants in the most recent filing window: Commonwealth Scientific and Industrial Research Organisation, Lydian Labs Inc, Air Products and Chemicals Inc, and Shenghwa New Energy Technology (Dongying) Co., Ltd. Their recent record counts are one, four, three, and one respectively.
