Overview
What this landscape covers
This landscape tracks patent families filed against powder feedstock formulated specifically for titanium alloy selective laser melting (SLM) — the alloy chemistry, particle-size distribution, and preparation routes that feed metal additive manufacturing systems, rather than SLM machine hardware or generic powder metallurgy. The scope is drawn from 54 published records spanning 2015 through the 2026 data cut-off, classified under powder metallurgy, additive manufacturing, and alloy IPC codes.
Filing activity is still young and concentrated: a handful of Chinese university and aerospace-linked assignees account for the leading positions, while most of the field consists of single-filing entrants testing narrow compositional or process claims. Publication lags filing by roughly 18 months, so the most recent years in the trend understate real activity.

The Data
Filing trends and technology composition
The record set skews recent and concentrates heavily in powder metallurgy and additive manufacturing classifications, with alloy treatment and biomedical-adjacent classes appearing as secondary, thinner branches.
A young field accelerating from a standing start
Published records were effectively zero in 2017 and reached 3 by 2021; from there filings nearly tripled to 9 by 2024, the peak year so far and the last year the trend can be read as complete. 2025 and 2026 figures will keep rising as later filings publish.
Publication lags filing by roughly 18 months, so 2025 onwards are still filling in. Growth rates on this page therefore end at 2024; running them to the last bar would understate the field.
Powder metallurgy and additive manufacturing dominate the classification mix
B22F (powder metallurgy) appears on 53 of 54 records and B33Y (additive manufacturing) on 47, confirming that almost every filing in scope treats the powder itself as the inventive subject rather than a downstream use. C22C (alloys) reaches 57.4% of records, showing alloy composition is a frequent second claim axis, while C22F, A61L, C23C, A61F and B29C form a thinner set of adjacent branches touching heat treatment, sterilisation, coatings and implant-specific claims.
Shares are the percentage of the 54 records in scope. A patent can carry several IPC classes, so the shares add up to more than 100%.

US20240123502A1 — Titanium alloy powder for selective laser melting 3D printing
SHANGHAI JIAO TONG UNIVERSITY
Filed by Shanghai Jiao Tong University, this 2024 filing claims a titanium alloy powder for SLM with a defined weight-percentage window of aluminium and vanadium, balance titanium plus inevitable impurities, produced via a specific vacuum consumable electric arc melting, forging and bar-processing route ahead of powder atomisation.One of the few US-filed records in a field otherwise concentrated in Chinese receiving offices.

Citation counts favour older filings that have had more time to accumulate citations inside this corpus — read them as a signal of influence, not of current commercial 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.

What the numbers mean for a filing strategy
Three patterns matter more than any single ranking: how concentrated ownership actually is, where the classification density sits, and how fast the field is moving.
Concentration
27.8%
of 54 records held by top 5 assignees
Ownership is thinner than the leader suggests
The leading assignee holds 4 records out of 54, and the top 5 combined reach only 27.8% of all records in scope. That leaves the majority of the field to a long tail of single- and double-filing entrants — a sign that no one has yet locked up the core compositional claims.
Top 10 combined reach 46.3% of all 54 records.
Growth
+200%
2021 to 2024 filing growth
Activity is accelerating, not plateauing
Published filings grew from 3 in 2021 to 9 in 2024, the last year the trend can be treated as complete given an 18-month publication lag. That trajectory points to a field still being actively staked out rather than one settling into maturity.
2017 filings were effectively zero; 2024 is the peak year so far.
Classification density
98.1%
of records classified under B22F
Powder metallurgy claims are almost universal
B22F appears on 53 of 54 records and B33Y on 47, meaning nearly every filing treats the powder feedstock itself, not just its downstream printing use, as the inventive core. C22C alloy claims sit on top of that in 57.4% of records, marking composition as the dominant second claim axis.
C22F, A61L, C23C, A61F and B29C together form a much thinner adjacent set.
Geography
46 of 54
records filed via a Chinese receiving office
Filing activity is concentrated in China
China accounts for 46 of the 54 records, with the United States, Russia and the WIPO PCT route making up the remainder in small numbers. Any freedom-to-operate check for this feedstock should start with Chinese-language prior art rather than treating US or PCT filings as representative of the field.
US: 4, Russia: 2, WIPO (PCT): 2.

Where to take this analysis
A landscape snapshot tells you what has already been claimed. Turning that into a filing or freedom-to-operate decision means going deeper on the specific compositional and process claims that sit closest to your own work.

Explore claim charts in EurekaTrack the thinner adjacent branches
C22F, A61L, C23C and A61F each cover under 20% of records — thin enough that a well-drafted claim in heat treatment, sterilisation or coatings could still stake genuinely open ground.

FAQ
Common questions on this landscape
Ownership in this field is dispersed rather than dominated by one or two players. The leading assignee holds 4 of the 54 records in scope, and the top 5 assignees combined account for only 27.8% of all records. The top 10 reach 46.3%, which means more than half the field is held by entities appearing once or twice — mostly Chinese universities and aerospace-linked research institutes. This spread suggests the core compositional claims are not yet locked up by any single filer.
It is growing. Published filings rose from effectively zero in 2017 to 3 in 2021 and reached 9 by 2024, a +200% increase over that three-year span and the field's peak year so far. Figures for 2025 and 2026 will look lower in the raw data, but that reflects the roughly 18-month lag between filing and publication rather than an actual slowdown. Read the 2021-2024 window as the reliable trend.
B22F, powder metallurgy, appears on 98.1% of the 54 records in scope, and B33Y, additive manufacturing, appears on 87.0% — together confirming that the powder feedstock itself, not just its use in a printer, is the inventive subject in almost every filing. C22C, alloys, sits underneath that in 57.4% of records as the dominant secondary claim axis covering composition. Thinner classes such as C22F, A61L, C23C, A61F and B29C mark adjacent, less-crowded territory in heat treatment, sterilisation, coatings and implant-specific claims.
China is by far the dominant receiving office, with 46 of the 54 records in scope filed there, reflecting the concentration of university and state-linked aerospace assignees in the ranking. The United States accounts for 4 records, and Russia and the WIPO PCT route each account for 2. A freedom-to-operate review for this feedstock category should prioritise Chinese-language prior art rather than assuming US or PCT coverage is representative.
US20240123502A1, filed by Shanghai Jiao Tong University and published in 2024, claims a titanium alloy powder for SLM defined by a specific weight-percentage window of aluminium and vanadium with the balance titanium and inevitable impurities, made via a defined vacuum consumable electric arc melting and forging route ahead of powder production. It blocks filings that fall inside that same compositional window and preparation sequence, but it does not foreclose different alloy systems, different weight-percentage ranges, or powder-production routes that skip the arc-melting and forging steps described. Anyone designing around it should look closely at the specific numeric ranges and the melting-and-forging process claims rather than the general concept of titanium SLM powder.

Patent data carries inherent limitations: recent filings (typically the most recent 18–24 months) are under-counted due to standard publication lag; counts may be reported at either a patent-family or a patent-record basis and are not always directly comparable; classification, applicant-name, and citation data may contain errors, duplicates, or omissions; and the underlying search query defines and constrains the scope shown.
