- Filing growth has flattened. activity climbed from 2 filings in 2017 to a peak of 29 in 2025, but the 2022 midpoint of 19 shows the curve is no longer accelerating.
- China dominates the filing base. 105 of the tracked records were filed at the Chinese receiving office against 11 in the US and 8 at the EPO, concentrating prior art and examiner precedent in one jurisdiction.
- Momentum is cooling even among top filers. several of the most active assignees, including Shanghai Jiao Tong University and North University of China, show 0 filings in the latest year and year-on-year drops of 80-100%.

Filing growth compares 2021 (16 records) with 2024 (26) — a three-year span. 2024 is the most recent year we treat as complete: publication lags filing by roughly 18 months, so 2025 onwards are still filling in and any growth rate that ends there would understate the field. Top-5 share is the combined record count of the five largest assignees divided by all 136 records in scope (CR5), not by the ranked leaders only.

Overview
What this landscape covers
This landscape tracks patent families at the intersection of magnesium alloy composition and additive manufacturing processes: laser powder bed fusion, wire-arc AM, and 3D-printed magnesium parts claimed alongside alloy or wrought-magnesium subject matter. The dataset spans 136 published patent families filed between 2015 and mid-2026, indexed against IPC classes covering additive manufacturing hardware, alloy composition and non-ferrous metal treatment.
Because publication typically lags filing by around 18 months, the 2025-2026 figures in this dataset are almost certainly undercounts of actual filing activity; treat the most recent year as a floor, not a ceiling.

The data
Filing trend and technology composition
Two views of the same 136 families: how filing volume has moved year over year, and which IPC subclasses carry the claim density.
A decade of uneven growth
Filings rose from 2 in 2017 to a peak of 29 in 2025. The 2022 midpoint of 19 sits well below a straight-line trajectory to the peak, which points to a burst of filing activity concentrated in the last few years rather than steady compounding growth. The partial 2026 count of 4 should be read as an artefact of publication lag, not a real slowdown yet.
Additive manufacturing and alloy claims dominate
B33Y (additive manufacturing processes, 115 records) and C22C (alloys, 98 records) are the two largest subclasses, confirming that most filings pair a specific AM process with alloy composition claims rather than treating either in isolation. B22F (powder metallurgy, 89) and C22F (non-ferrous treatment, 48) form a secondary cluster around powder feedstock and post-process heat treatment. Smaller counts in A61L (sterilising, 25), B23K (welding, 22), B21C (extrusion, 12) and C23C (coating, 10) mark biomedical and finishing applications as adjacent, lower-density areas.
Shares are the percentage of the 136 records in scope. A patent can carry several IPC classes, so the shares add up to more than 100%.

Citation counts favour older records simply because they have had more time to be cited; read them as a signal of influence within this corpus, not as a ranking 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 decision
Three findings that shape where a new filing would sit relative to existing claims.
Filing pace
19 → 29
2022 to 2025 filings
Growth has slowed since the 2025 peak
The jump from a 2022 midpoint of 19 filings to a 2025 peak of 29 looks like acceleration, but the partial 2026 count of 4 combined with publication lag means the true 2025-2026 trajectory is still forming. Read the peak as the latest confirmed data point, not proof of continued growth.
Filing trend, 2017-2026
Jurisdiction concentration
105 of 136
records filed in China
Prior art is concentrated in one office
105 of the 136 tracked records were filed at the Chinese receiving office, versus 11 in the US and 8 at the EPO. A freedom-to-operate review that skips Chinese-language prior art will miss most of the relevant claim history in this field.
Receiving office split
Claim clustering
115 & 98
B33Y and C22C record counts
AM process and alloy composition claims are paired, not separate
B33Y (additive manufacturing) appears in 115 records and C22C (alloys) in 98, the two largest subclasses in the dataset. Most filers are claiming a specific process step together with an alloy composition, so a new filing that only addresses one side of that pair is filing into a gap rather than a novel combination.
IPC composition
Assignee momentum
-80% to -100%
YoY change, top assignees
Even leading filers have gone quiet
Jilin University dropped 80% year-on-year to 1 filing in the latest year, while North University of China and Shanghai Jiao Tong University each fell to 0, a 100% decline. That does not necessarily mean disengagement — it may reflect publication lag on 2025-2026 applications — but it does mean the visible leaderboard understates who is actually active right now.

Players
Who is filing, and where the field is thinning
The assignee base is led by Chinese universities and research institutes, with co-filing pairs suggesting joint industry-academia projects rather than a single dominant corporate filer.
Filer type
7 pairs
co-assignee collaborations
Collaboration is limited and university-led
Only 7 co-assignee pairs appear across 136 families. The strongest, Shanghai Jiao Tong University with Shanghai Institute of Precision Mechanics, Chinese Academy of Sciences, has just 2 joint filings, which indicates most work here is filed by a single institution rather than through sustained joint ventures.
Co-assignee pairs
Momentum
0 in latest year
for several top-cited filers
Recent-year output has dropped across former leaders
Chongqing University, Nanjing University of Aeronautics and Astronautics and BIORETEC all show 0 filings in the latest tracked year. Combined with publication lag, this makes it hard to tell whether these filers have stopped work or simply have applications still in the pipeline.

Geography
105 CN filings

The competitive base is not evenly distributed
A company benchmarking freedom-to-operate in the US or Europe is working against a much thinner set of granted claims than a company operating in China, where the bulk of the prior art sits.

What's next
Where to take this analysis
The dataset points to open questions that a static report cannot answer on its own.
Model the 2025-2026 filing lag
Publication lag means the last 12-18 months of filings are still arriving. Re-running the trend query periodically will reveal whether the 2025 peak holds or whether it was a temporary spike.

FAQ
Common questions about this landscape
The assignee base is led by Chinese research universities and institutes rather than a single dominant corporation. Filers such as Shanghai Jiao Tong University, Jilin University and North University of China appear repeatedly across the 136 tracked families, but recent-year momentum has slowed sharply for several of them, with year-on-year drops of 80-100% in the latest tracked year. This suggests a fragmented, academically-driven filing base rather than a concentrated corporate lead.
Of the 136 records in this dataset, 105 were filed at the Chinese receiving office, compared with 11 in the US and 8 at the EPO. This reflects both the concentration of magnesium alloy AM research at Chinese universities and China's broader pattern of high domestic filing volume in advanced manufacturing fields. Anyone assessing freedom to operate globally should treat Chinese-language prior art as the primary body of claims to clear, not a secondary check.
Filings rose from 2 in 2017 to a peak of 29 in 2025, but the 2022 midpoint of 19 shows growth was uneven rather than steadily compounding. The partial 2026 figure of 4 filings looks like a decline, but publication typically lags filing by around 18 months, so recent-year counts are likely undercounted. The honest read is that the field grew through the early 2020s and its current trajectory is not yet clear from the data.
LPBF and other additive manufacturing processes fall under IPC class B33Y, which covers 115 of the 136 records in this dataset, making it the single largest technology cluster. Most of these filings pair a specific AM process step with an alloy composition claim, as seen in the representative filing US20260042148A1, which claims a scan-strategy method for smooth-surface magnesium scaffolds. This means process claims are rarely filed in isolation from composition claims in this space.
Filing density is comparatively low in coating and surface deposition (C23C, 10 records), metal extrusion and drawing (B21C, 12 records), and welding or brazing of AM parts (B23K, 22 records), compared with the dense core of B33Y and C22C claims. These lower counts do not guarantee open claim space, since they may reflect narrower search scope rather than genuine absence of prior art, but they are reasonable areas to investigate further before filing in the crowded core.
Citation counts in this corpus, such as the 25 citations on CN110983135A or 21 on CN112404453A, reflect how long a record has been available to be cited more than how commercially important it is today. Older filings accumulate citations simply by being in the corpus longer, so a highly-cited 2020 filing is not necessarily more relevant than a lightly-cited 2025 filing. Use citation rank as a signal of historical influence within this search, not as a current importance score.
