Multi-Jet Fusion Scale-Up Patents: Leaders & White Space 2026
- Filing peaked in 2019 at 23 records and has since flattened, with the 2022 midpoint at 9 — this branch is not accelerating.
- Powder metallurgy and 3D printing IPC codes co-occur in most filings B22F, B33Y and C22C between them cover the bulk of the 49 families, showing scale-up claims are being built at the powder-and-alloy layer, not just the printer layer.
- The United States leads receiving offices with 12 filings ahead of the EPO at 10 and WIPO/PCT at 7 — filing strategy here is still largely national rather than globally pooled.
What this landscape covers
Multi-Jet Fusion scale-up and mass production patenting sits at the intersection of powder-bed additive manufacturing and traditional metallurgy. The dataset behind this page tracks 49 patent families published between 2015 and mid-2026 that combine Multi-Jet Fusion (or MJF) terminology with claims to high-volume production, serial production, or production scale-up. That framing matters: this is not a landscape of MJF printing in general, it is specifically the subset of filings that stake a claim on making the process work at production volume rather than prototype volume.
Filing activity is concentrated in a narrow band of years rather than building steadily. Because publication typically lags filing by around eighteen months, the most recent year in the trend line is understated and should be read as a floor, not a ceiling.

Filing trend and technology composition
The two views below show when scale-up claims were filed and where they sit in the classification system. Together they indicate a field that surged once and has not repeated that surge.
A single peak year, not a sustained climb
Filings ran from 2 in 2017 to a peak of 23 in 2019, then eased back toward a midpoint of 9 in 2022. That shape — a spike followed by a plateau — is more consistent with a wave of filings tied to specific product launches or process patents than with a technology still in an early growth phase. A reader evaluating freshness of claim space should weight pre-2019 and 2019-era filings heavily, since that is where the density actually is.
Powder and alloy classes dominate over pure printing controls
B22F (powder metallurgy), B33Y (additive manufacturing) and C22C (alloys) each appear in well over half of the 49 families, while G05B (control and regulating systems) and B21D (sheet-metal working) sit at only 5 records apiece. This tells a specific story: the patented ground in MJF scale-up is mostly about powder formulation, particle handling and alloy chemistry suited to high-volume runs, not about the control software or line-integration engineering that a production floor also needs. A61F (implants and prostheses) appears only 3 times, suggesting medical end-use is a minor rather than dominant application here.
Shares are the percentage of the 49 records in scope. A patent can carry several IPC classes, so the shares add up to more than 100%.

Method for the obtaining of cost effective geometrically complex pieces
A method for the production of complex geometry, and even large, highly performant metal-comprising components in a cost effective way. The method is also indicated for the construction of components with internal features and voids. The method is also beneficial for light construction. The method allows the reproduction of bio-mimetic structures and other advanced structures for topological performance optimization.Filed as a continuation of the same family's earlier WO publication, this record is one of the most-cited in the dataset and illustrates the core claim pattern: cost-effective production of geometrically complex, internally featured metal parts at scale.

Citation counts inside a bounded corpus like this one skew toward older filings, since they have had more time to accumulate citations. Treat the ranking as a signal of influence on subsequent filers, not as a ranking of current commercial importance.
Publication numbers are shown where the record carries one (8 of 8 rows); clicking a row searches Eureka by that number.

Three patterns stand out once the trend and classification data are read together: a filing wave that has already crested, a claim base weighted toward materials rather than controls, and a jurisdiction pattern still centred on the US and Europe.
The surge already happened
Filings peaked at 23 in 2019 and have not returned to that level since, with the 2022 midpoint at only 9. New entrants should treat pre-2020 filings as the densest prior art rather than assuming the newest publications carry the most weight.
Powder and alloy claims outweigh control claims
B22F, B33Y and C22C each cover the majority of records, while G05B control-system claims sit at only 5. Scale-up patenting here has concentrated on what goes into the machine, not how the machine is orchestrated on a production line.
Filing strategy is still regional
The United States leads, with the EPO close behind and WIPO/PCT filings trailing both. That gap suggests many applicants are not yet pursuing broad multi-territory protection for scale-up claims specifically, leaving room for global filing strategies that current players have not fully executed.
Eureka can read the same corpus for gaps instead of for coverage: under-claimed branches adjacent to multi-jet fusion scale-up and mass production, with the prior art for and against each one.
Who is filing, and where the field is thin
Assignee activity in this dataset is modest in absolute terms — 49 families total — and recent-year momentum is largely flat or negative across the named organisations, with only one showing a filing in the latest year.
Only one assignee filed in the most recent year
Wavs Custom Inc is the sole organisation in the recent-momentum data with a filing in the latest tracked year; every other listed assignee shows zero, including one recording a -100% year-over-year drop. This is a field where recent activity is thin enough that a single new filer can visibly change the picture.
Legacy powder-metallurgy names have gone quiet recently
Hoeganaes Corp, a name closely tied to powder metallurgy generally, shows no filings in the latest year within this dataset, consistent with the broader flattening seen since the 2019 peak.
Prosthetics filers are a small but distinct group
Alt Bionics Inc appears among the tracked assignees and the A61F implants/prostheses classification covers only 3 of the 49 records, marking medical end-use as a narrow specialism rather than a mainstream application of MJF scale-up claims.

Where to take this analysis
The trend and classification data point to specific next steps depending on whether the goal is freedom-to-operate, white-space filing, or competitor tracking.
Check freedom-to-operate against the powder-and-alloy cluster
With B22F, B33Y and C22C covering the bulk of filings, any new scale-up process touching powder formulation or alloy selection should be checked against this cluster first, weighted toward the 2019-era peak filings.
Run a freedom-to-operate search in EurekaExplore the control-systems gap
G05B control and regulating claims sit at only 5 of 49 records, well below the materials side. A production-line integration or scheduling claim may face a thinner prior-art field here than in powder chemistry.

With only Wavs Custom Inc showing activity in the latest tracked year, monitoring that filer's family closely may reveal where the next wave of scale-up claims is headed.
Set up assignee monitoring in EurekaCommon questions about Multi-Jet Fusion scale-up patents
This landscape specifically tracks filings that combine Multi-Jet Fusion terminology with language about high-volume production, serial production, or production scale-up, rather than every patent that mentions MJF printing. That distinction matters because general MJF printing patents may cover prototyping or single-part production, while scale-up patents specifically claim methods, powders, or systems aimed at repeatable high-volume manufacturing. The dataset behind this page contains 49 patent families meeting that narrower definition, filed between 2015 and mid-2026.
Filing activity in this dataset is spread across a number of assignees with no single dominant filer showing sustained recent momentum; most named organisations, including Hoeganaes Corp, show zero filings in the latest tracked year. Wavs Custom Inc is the one assignee with a recorded filing in the most recent year. Given the overall filing count of 49 families, this remains a field with room for new entrants rather than one locked up by a handful of large players.
The data shows filings rising to a peak of 23 in 2019 before easing to a midpoint of 9 by 2022, with 2026 figures still partial due to publication lag. This pattern is more typical of a concentrated wave of filings around specific process or product launches than of a technology still in an expansion phase. Because publication lags filing by roughly eighteen months, the most recent years understate true filing activity, so the decline should not be read as definitive without waiting for later data to catch up.
The IPC composition shows heavy concentration in powder metallurgy (B22F), additive manufacturing (B33Y), and alloys (C22C), each present in over half of the 49 families, while control and regulating systems (G05B) and sheet-metal working (B21D) each account for only 5 records. That gap suggests line-integration software, production scheduling, and hybrid sheet-metal/MJF workflows carry comparatively thin patent coverage relative to their practical importance in a production environment, making them worth a closer freedom-to-operate and white-space review.
The United States leads receiving offices with 12 filings in this dataset, followed by the European Patent Office at 10 and WIPO/PCT filings at 7, with India, Canada, and Germany trailing further behind. The relatively low PCT count compared to national filings suggests many applicants have pursued regional rather than global protection for scale-up-specific claims, which may leave gaps in territories outside the US and Europe for parties considering a broader international filing strategy.
