Chemical & Process Engineering · Patent LandscapeMicroreactor Process Intensification Patents: Who Holds the Core Claims
- Filing is accelerating, not steady: annual filings dropped to just 1 in 2022 before climbing to a peak of 4 in 2026, a pattern easy to miss without the year-by-year trend.
- One classification dominates almost completely: B01J (catalytic and physical processes) appears in 134 of 144 records, while separation (B01D) and heterocyclic chemistry (C07D) each cover just 10.
- Influence concentrates in one inventor-assignee pairing: the strongest co-filing relationship in the dataset links a single named inventor to one assignee across 11 shared records, more than any other pair.

Overview
What this patent landscape covers
This landscape covers 144 patent families published between 2015 and mid-2026 that combine microreactor or microchannel reactor technology with explicit process-intensification language: enhanced mass transfer, enhanced heat transfer, or intensified reaction. The search is anchored on IPC classes B01J19/24, B01J19/00 and B01F, covering chemical and physical process apparatus and mixing equipment.
Filing activity has been uneven rather than steadily rising, falling to a single filing at the 2022 midpoint before climbing back to a peak of 4 in the most recent tracked year. Because publication lags filing by roughly 18 months, the most recent year's count is understated and should be read as a floor, not a ceiling.

Filing Data
Filing trends and technology composition
The filing curve and IPC spread below show where microreactor process-intensification claims concentrate and how filing activity has moved since 2017.
Filing activity is still accelerating
Annual filings moved from 2 in 2017 to a peak of 4 in 2026, with a midpoint of just 1 filing in 2022. Because publication typically lags filing by around 18 months, the true 2025-2026 filing level is almost certainly higher than currently published records show.
B01J dominates, with hydrocarbon and organic chemistry close behind
B01J (chemical and physical processes, catalysis) appears in 134 of 144 records, making it the near-universal core classification. C10G (hydrocarbon refining) and C07C (acyclic and carbocyclic compounds) each cover roughly a third of the corpus, while B01D (separation) and C07D (heterocyclic compounds) are the thinnest branches at 10 records each.
Shares are the percentage of the 144 records in scope. A patent can carry several IPC classes, so the shares add up to more than 100%.

Apparatus and Methods For Nanoparticle Generation and Process Intensification of Transport and Reaction Systems
IDEX MPT INC.
Apparatus, systems and methods are provided that utilize microreactor technology to achieve desired mixing and interaction at a micro and/or molecular level between and among feed stream constituents. Feed streams are fed to an intensifier pump at individually controlled rates, e.g., based on operation of individually controlled feed pumps. The time during which first and second feed streams are combined/mixed prior to introduction to the microreactor is generally minimized, thereby avoiding potential reactions and other constituent interactions prior to micro- and/or nano-scale interactions within the microreactor. Various microreactor designs and geometries may be employed, including staged feed-introduction configurations.Filed by IDEX MPT INC., published 2009-10-29; cited 76 times within this corpus.

What the filing and citation data signals
These patterns come directly from the assignee, citation and co-filing data in this corpus and point to where claim scope is concentrated versus where it remains open.
Citation concentration
144 citations
top-cited record
One record anchors the whole citation network
The most-cited record in this corpus, covering hydrocarbon-to-oxygenate conversion, has been cited 144 times, nearly 50% more than the next most-cited record. This level of concentration means later filers in adjacent hydrocarbon-conversion routes are very likely to have cited or been examined against this document.
Citation counts favor older records; treat this as historical influence, not current relevance.
Co-filing pattern
11 shared records
strongest pair
A small group of named inventors and one assignee dominate joint filings
Only 10 co-assignee pairs exist across the corpus, and the strongest pairing links one assignee with a single named inventor across 11 records, with a second pairing between two named inventors reaching 9. This is a tight, identifiable filing network rather than a broad field of independent collaborators.
Co-filing concentration can indicate a defensible core patent family controlled by a small group.
Technology concentration
134 of 144
records in B01J
Catalytic process claims are nearly universal
B01J appears in 134 of 144 records, meaning almost every filing in this corpus touches catalytic or physical-process claim language. Downstream classifications like C10G and C07C each cover under a third of the corpus, showing that most differentiation happens within the catalytic core rather than in separate technology branches.
High density in B01J means claim space there is occupied, not that further catalytic filings are pointless.
Jurisdictional spread
41 US filings
leading office
US filings lead but PCT coverage is substantial
The United States receives the most filings at 41, but Europe and WIPO/PCT each account for 21 filings, roughly half the US volume, indicating many applicants are pursuing international protection alongside a US-first strategy rather than filing only domestically.
China and India each show 12 filings, a smaller but non-trivial share of this corpus.

Assignee
11 shared records
strongest co-filing pair
Velocys-linked assignee and Tonkovich Anna Lee
This pairing is the strongest co-filing relationship in the corpus, appearing together on 11 records, consistent with a jointly developed and jointly held Fischer-Tropsch microchannel reactor patent family.
Latest-year momentum for this assignee is 0, consistent with the corpus-wide publication lag.
Assignee
9 shared records
second co-filing pair
Tonkovich Anna Lee and Daly Francis P
A second strong inventor pairing appears on 9 shared records, overlapping with the first pair and suggesting a small, stable inventing team behind much of the earlier Fischer-Tropsch microchannel filing activity.
No filings recorded for this pairing in the latest tracked year.

B01D and C07D each cover only 10 of 144 records here; a targeted search of adjacent non-microreactor separation patents would confirm whether this gap is genuinely open.
Search adjacent classifications in EurekaTrack assignee momentum going forward
Recent-year filings across the named assignees in this corpus currently show zero momentum, which may reflect publication lag rather than a real slowdown; monitoring the next 12-18 months of publications will clarify this.

FAQ
Common questions about microreactor process-intensification patents
Process intensification refers to design approaches that dramatically increase mass and heat transfer rates within a reaction system, usually by shrinking reactor channel dimensions to the micro or sub-millimeter scale. In this patent corpus, the concept is most often claimed alongside catalytic processes (IPC class B01J, present in 134 of 144 records) and mixing apparatus (B01F, 32 records). The practical effect is that reactions which would otherwise require large vessels and long residence times can run faster and with tighter control, which is why refining and organic chemistry filings dominate this space.
Citation data in this corpus points to a cluster of Fischer-Tropsch microchannel reactor patents as the most influential prior art, with the single most-cited record reaching 144 citations. The strongest co-filing relationship is between the Velocys-linked assignee and named inventor Tonkovich Anna Lee, appearing together on 11 records, with a second strong pairing between Tonkovich Anna Lee and Daly Francis P on 9 records. These figures reflect citation influence within the searched corpus and should be read as a signal of past prominence rather than current filing activity, since citation counts favor older records.
Yes, based on the tracked filing trend, annual filings grew from 2 in 2017 to a peak of 4 in 2026, after dipping to 1 filing at the 2022 midpoint. This pattern indicates renewed and accelerating interest rather than steady growth throughout the period. Readers should treat the most recent one to two years of any filing trend cautiously, since patent publication lags the actual filing date by roughly 18 months, meaning true recent activity is likely understated in the published record.
The United States leads with 41 receiving-office filings in this corpus, followed by Europe (EPO) and WIPO/PCT filings tied at 21 each, then Canada at 17, and China and India each at 12. This distribution suggests the US remains the primary jurisdiction of first filing or strategic protection for this technology, with PCT filings indicating applicants are also pursuing broad international coverage rather than relying on national filings alone.
Separation processes (IPC class B01D) and heterocyclic compound synthesis (C07D) are the thinnest branches in this dataset, each appearing in only 10 of 144 records compared to 134 for the core catalytic classification B01J. This gap suggests that integrated reaction-and-separation microreactor designs, and microreactor routes to heterocyclic or fine-chemical intermediates specifically, have not been claimed as densely as bulk catalytic and hydrocarbon-processing routes. That said, thin filing density in a patent search is not proof of open technical ground, and a dedicated freedom-to-operate search is still needed before relying on it.
