Homogenizer Patents: Who Leads, Where the Gaps Are 2026
- Filings have plateaued, not grown. The peak year so far is 2022 at 4 records, and the trend from 2017 to 2026 shows no sustained climb — this is a flat or declining filing pattern, not an emerging one.
- No single company dominates. The leader holds just 3 records out of 42, and the top 5 combined account for only 26.2% of all records in scope — concentration is shallow across a long tail of single- and double-filing entrants.
- Filings cluster in food and dairy classes, not core mixing engineering. A23L (foods) appears on 57.1% of records and A23C (dairy) on 26.2%, while B01F (mixing & stirring), the equipment-design class, sits at 23.8% — most activity is application-side, not mechanism-side.
A shallow, application-led field
The dataset covers 42 published records filed against homogenizer, high-pressure homogenization and emulsification equipment search terms, cross-referenced against droplet size reduction, valve wear, energy consumption, aseptic design and microfluidization within IPC classes A23C3, B01F25 and A23L3. Filing activity runs from 2015 through the 2026 cut-off, with China accounting for 27 of the receiving-office filings — by far the largest single jurisdiction, ahead of the United States, United Kingdom and PCT routes combined.
Publication typically lags filing by around 18 months, so the most recent year in any trend understates real activity. Read the tail of the chart as incomplete rather than as a genuine drop-off.
Filing trend and technology composition
Two views of the same 42 records: how filing activity has moved year over year, and which IPC subclasses the records sit in.
Flat since the 2022 peak
Filings rose from 1 in 2017 to a peak of 4 in 2022, the midpoint of the window, and have not exceeded that level since. That pattern reads as flat-to-declining rather than an accelerating field, though the final year or two is understated due to publication lag.
Food and dairy classes dominate over core mixing engineering
A23L (foods & non-alcoholic beverages) touches 57.1% of the 42 records and A23C (dairy products) 26.2%, well ahead of B01F (mixing & stirring) at 23.8% — the class that covers homogenizer mechanism design itself. A61K (medicinal preparations) at 16.7% and A23K (animal feed) at 11.9% show meaningful spillover into pharma-adjacent and feed-processing uses. Records can carry more than one class, so these shares add to more than 100% of the record total.
Shares are the percentage of the 42 records in scope. A patent can carry several IPC classes, so the shares add up to more than 100%.

High-Pressure Homogenizer and Method for Manufacturing Graphene Using the Same
A high-pressure homogenizer built around a channel module with a microchannel split into first and second flow channels arranged in sequence. The first flow channel carries a set of baffles partitioning the microchannel into multiple spaces, and the second flow channel carries a second set of baffles doing the same — with baffles from the two sets interleaved so that at least one first baffle sits between two adjacent second baffles.Filed by LG Chem, published 2022-05-12 — notable for applying homogenizer architecture outside food/dairy processing, to graphene manufacturing.

Citation counts favour older records simply because they have had more time to be cited; treat them as a signal of influence within this corpus, not a ranking of current importance.
Patent titles are shown in the language they were filed in, not translated, so that each record stays verifiable against the original filing — a translated title will not match in Eureka or in any national register. Each row carries its publication number; clicking a row searches Eureka by that number.

Three read-outs from the ranking, the citation table and the jurisdiction split that matter for a freedom-to-operate or whitespace assessment.
Leadership is shallow
The single largest assignee holds 3 records; by the tenth-ranked assignee that figure is down to 1. With the top 5 combined covering only 26.2% of all 42 records and the top 10 reaching 47.6%, no single company has locked up the claim space — the field is fragmented across 35 ranked assignees.
Filing activity is concentrated in China
China accounts for 27 of the tracked filings, versus 6 in the United States and 3 each in the United Kingdom and via WIPO/PCT. That skew suggests domestic Chinese food-processing and dairy manufacturers are the more active filers in this space relative to Western equipment makers.
Older filings still anchor the field
The most-cited record in the set, on microfibrillated cellulose suspension production, carries 29 citations; a 1989 anaerobic pasteurizing patent still draws 15. Heavy citation to decades-old prior art is typical in a mechanically mature category — it signals influence, not that the underlying technology is current.
Eureka can read the same corpus for gaps instead of for coverage: under-claimed branches adjacent to homogenizers and emulsification equipment, with the prior art for and against each one.
A fragmented field with no dominant filer
35 assignees are ranked in this dataset, and momentum data shows the recent-year filing count sitting at zero for several of the more active historical names — consistent with the flat trend since the 2022 peak.
Top spot is a narrow lead
The leading assignee holds 3 of the 42 records in scope, only marginally ahead of the field. That gap is too narrow to describe as dominance — it is a lead within a long tail.
Drop-off starts early
By fifth place, filing counts have already fallen to 2 records, and by tenth place to 1. Most of the ranked list sits at single-digit, largely single-record, filing activity.
No assignee is currently accelerating
Recent-year momentum data shows multiple previously active assignees, including dairy and biological-science filers, at zero filings in the latest tracked year. That is consistent with the overall flat-to-declining trend rather than a sign any one of them has exited the space.

Where to take this analysis
The dataset points to a fragmented, application-led field with room to check specific mechanism-level claims before committing to a filing strategy.
Map the B01F class in detail
Only 23.8% of records sit in the mixing & stirring class that covers homogenizer mechanism design directly — worth a closer read given most activity is food/dairy application claims layered on top.

The assignee ranking is fragmented: the top-ranked company holds only 3 of the 42 records in scope, and by fifth place the count is already down to 2. The top 5 assignees combined account for 26.2% of all 42 records, and the top 10 for 47.6% — so no single company controls a dominant share of the claim space. This is a field with 35 ranked assignees rather than a handful of gatekeepers, which matters for freedom-to-operate work because blocking risk is spread thin rather than concentrated in one portfolio.
Based on the tracked filing trend from 2017 to 2026, activity peaked in 2022 at 4 records and has not exceeded that level since, which reads as flat or declining rather than growing. Publication lag of roughly 18 months means the last year or two of data understates true filing activity, so the most recent apparent drop should not be read as a hard stop. Overall, this looks like a mature filing pattern rather than an accelerating one.
China is by far the largest receiving office in this dataset, with 27 of the 42 tracked filings, followed by the United States at 6 and the United Kingdom and WIPO/PCT routes at 3 each. That concentration suggests domestic Chinese food-processing, dairy and biotech manufacturers are filing more actively in this specific technical intersection than equipment makers elsewhere. Anyone assessing regional competitive risk should weight Chinese filings heavily in this category.
IPC data shows A23L (foods and non-alcoholic beverages) on 57.1% of the 42 records and A23C (dairy products) on 26.2%, both ahead of B01F (mixing and stirring), the class most associated with homogenizer mechanism design, at 23.8%. There is also meaningful overlap into A61K (medicinal preparations, 16.7%) and A23K (animal feed, 11.9%). Because a single record can carry multiple IPC classes, these figures add up to more than 100% of the record total, reflecting genuine cross-application filing rather than double-counting error.
US20220144643A1 claims a high-pressure homogenizer with a channel module built from two sequential flow channels, each fitted with its own set of baffles that partition the microchannel into multiple spaces, with baffles from the two sets interleaved. It was filed by LG Chem and published in 2022, and it is notable for applying homogenizer architecture to graphene manufacturing rather than a food or dairy application. Anyone designing a multi-stage baffled microchannel homogenizer for particle or material processing should review this claim structure specifically, since it sits outside the dominant food/dairy cluster where most other filings concentrate.
