Patent Landscape · Construction Materials3D Concrete Printing Materials and Toolpath: Patents Behind Buildability, Interlayer Bonding and Print-Path Control
- Concentrated at the top. The top 5 assignees hold 66.7% of all 18 records in scope, and the top 10 combined reach 94.4% — a small group is doing nearly all the documented filing.
- Filing has gone flat, not steadily up. Activity peaked at 5 records in 2024 after a slow build from zero in 2017, with the midpoint year sitting at just 2 — this is not a runaway growth curve.
- Shaping and additive-manufacturing classes dominate. B28B (shaping clay & cement products) and B33Y (additive manufacturing) each cover more than half of the 18 records, while structural classes like E04B barely register.

Overview
What this landscape covers
This landscape tracks patent filings at the intersection of 3D concrete printing materials and toolpath control — claims touching buildability, open time windows, interlayer bond strength, toolpath optimization, reinforcement integration strategy, surface quality and finishing. The scope spans 18 published records filed between 2015 and the 2026-07-31 data cut-off, drawn from a search string combining title/abstract terms for 3D concrete printing with claim/description terms for the specific technical problems that separate a printable mix and path from a merely extrudable one.
Publication lags filing by roughly 18 months, so the most recent year in the trend understates actual filing activity. Family counts, not raw document counts, are used throughout so continuation and multi-jurisdiction filing do not inflate any single applicant's footprint.

The Data
Filing trend and technology composition
Two views of the same 18 records: how filing activity has moved year over year, and which IPC subclasses carry the claim density.
Filing trend
Filings started from zero in 2017, sat at 2 by the midpoint year 2022, and peaked at 5 in 2024 — a flat-to-declining trend rather than sustained growth. The final year in scope is necessarily partial given publication lag.
Technology composition by IPC subclass
B28B (shaping clay & cement products) appears in 61.1% of the 18 records and B33Y (additive manufacturing) in 55.6%, confirming that most filings sit at the materials-and-process core rather than in adjacent structural or imaging classes. E04G (scaffolding & formwork) reaches 38.9%, while G06T (image processing) and G01D (measuring) each sit at 11.1%, and E04B (building structures) covers just one record — a single class share can exceed the record total because records carry multiple IPC codes.
Shares are the percentage of the 18 records in scope. A patent can carry several IPC classes, so the shares add up to more than 100%.

Citation counts inside this searched corpus favour older records and should be read as a signal of influence within the field, not as a measure of current commercial relevance.
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. Publication numbers are shown where the record carries one (4 of 4 rows); clicking a row searches Eureka by that number.

What the numbers say about this field
Three signals worth pulling apart before deciding where to file or search prior art.
Concentration
66.7% of 18 records
held by the top 5 assignees
A small group holds most of the documented claim space
The top 5 assignees account for 66.7% of all 18 records in scope, and the top 10 combined reach 94.4%. With a leader at 4 records and a long tail dropping to single filings by fifth place, this field has not yet attracted the broad multi-national filer base seen in more mature construction-tech categories.
Based on the assignee ranking of 14 companies, the full set the data endpoint returns.
Filing momentum
Peak year: 2024 (5 records)
midpoint 2022 = 2
Growth is flat, not accelerating
Filing moved from zero in 2017 to a midpoint of 2 records in 2022 before peaking at 5 in 2024. Several recent-year assignee tallies show 0 in the latest year, some with -100% YoY, which reads as episodic filing by individual labs and applicants rather than a sustained industrial ramp.
Publication lag means the final year in the window is understated.
Technology mix
B28B: 61.1% · B33Y: 55.6%
share of 18 records
Claims cluster on material shaping and the print process itself
B28B (shaping clay & cement products) and B33Y (additive manufacturing) each cover more than half of the 18 records, and E04G (scaffolding & formwork) reaches 38.9% — likely reflecting toolpath and support-structure claims. Structural integration (E04B, 5.6%) and sensing/measurement (G01D, 11.1%) are comparatively thin.
Class shares sum to more than 100% because records carry multiple IPC codes.

Players
Who is filing, and where the gate sits
The ranked leaders are a mix of university tech-transfer offices and individual or small-entity applicants rather than large construction or materials corporations, which shapes both the citation pattern and the openings below.
Leader
4 records
top-ranked assignee
A university-driven leader with no runaway lead
The top assignee holds 4 of the 18 records in scope, well ahead of the field but not a dominant blocking position on its own. Several of the ranked leaders are university research offices, consistent with the technology still being in an active-research phase.
Ranking covers 14 assignees, the complete set returned for this scope.
Co-filing
6 co-assignee pairs
across 18 records
Collaboration is limited and mostly bilateral
Only 6 co-assignee pairs appear across the 18 records, each linking exactly two parties. This points to largely independent research programmes rather than joint ventures or cross-licensing consortia forming around the technology.
Strongest pairs each recur once in the dataset.
Receiving offices
WIPO (PCT): 6
of documented filings
PCT and Korea carry the largest share of filings
WIPO (PCT) filings lead at 6, followed by South Korea at 4 and the United States at 3, with single filings each at the UAE, China and the EPO. The PCT weighting suggests applicants are keeping international options open before committing to national phase.
Receiving-office counts reflect where applications entered the system, not where inventors are based.

What's Next
Where to take this next
The dataset points to specific next steps depending on whether the goal is freedom-to-operate, portfolio strategy, or spotting where to file.
Check freedom-to-operate against the most-cited filings
The highest-citation records in this set, including the nanomaterial rheology-modifier and print-quality-monitoring filings, are the ones most likely to surface in an examiner's prior-art search. Map any planned claims against these before drafting.
Run a claim comparison in EurekaTrack the flat filing trend for a re-acceleration signal
With filing peaking at 5 records in 2024 and several leading assignees showing 0 in the latest year, a jump in filing volume would be an early signal that a commercial player is moving from research to product protection.
Set up filing-trend monitoring in EurekaExplore the under-claimed branches before they fill in
Structural integration and in-line sensing classes carry thin coverage today. A first-mover claim in these areas faces less prior art than the crowded B28B and B33Y core.

FAQ
Frequently asked questions
This landscape covers 18 published records filed between 2015 and the 2026-07-31 data cut-off, drawn from a search targeting buildability, interlayer bond strength, toolpath optimization, reinforcement integration, surface quality and finishing claims. That is a small, specific slice of the broader 3D concrete printing field, not a count of every concrete-printing patent filed worldwide. Because publication lags filing by roughly 18 months, the most recent year in the dataset understates true filing activity.
The ranking covers 14 assignees, with the leader holding 4 of the 18 records and the top 5 combined accounting for 66.7% of all records in scope. Most of the ranked leaders are university research or tech-transfer offices rather than large construction materials corporations, suggesting the field is still largely in an academic-research phase. The top 10 assignees together reach 94.4% of all records, leaving very little filing activity outside this group.
The trend is flat rather than steadily rising: filings moved from zero in 2017 to 2 records at the 2022 midpoint before peaking at 5 in 2024. Several of the leading assignees show zero filings in the most recent year, some down 100% year-over-year, which points to episodic project-driven filing rather than sustained industrial investment. Given the roughly 18-month publication lag, the true trajectory of the last one to two years cannot yet be read from this data.
Structural-element-level toolpath claims under E04B cover only one of the 18 records, and measurement or sensing claims under G01D cover just 11.1%, both thin compared with the 61.1% share held by core shaping claims under B28B. Reinforcement integration strategy and open time window control for mix chemistry also show limited dedicated coverage in this dataset. These gaps suggest room for a well-scoped first claim before the space fills in, though thin coverage in a narrow search does not guarantee the area is legally open — a full freedom-to-operate search is still required.
WO2025035063A2, filed by Applied Research Transformation, PLLC and published 2025-02-13, claims a 3D concrete printing quality monitoring and control system built around a camera assembly capturing surface image data and a computing device running image-analysis algorithms to generate control outputs in real time. It is one of the more recently cited filings in this landscape, reflecting active interest in real-time surface-quality feedback during printing. Anyone developing camera-based or image-driven print monitoring for concrete should review its specific claim language before designing a similar system.
