Patent Landscape · Advanced Materials & MetallurgyMagnesium Alloy Powder Metallurgy Patents: Filing Trends and Who Holds the Ground
- Filing has cooled since 2020. The peak year was 2020 at 16 filings, and the count at the 2022 midpoint had already dropped to 4 — this is a maturing, not an accelerating, field.
- No assignee shows momentum in the latest tracked year. Every one of the leading assignees, including Korea Institute of Industrial Technology (KITECH) and Netherlands Organisation for Applied Scientific Research (TNO), recorded zero filings in the most recent year — leadership here is inherited, not being actively defended.
- Alloys and powder metallurgy dominate, biomedical and casting sit downstream. C22C (204 records) and B22F (129) anchor the field, while A61L biomedical filings (12) and C21D heat treatment (9) mark thinner, more open branches.

Leading Jurisdiction
Filing growth compares 2021 (7 records) with 2024 (13) — 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 228 records in scope (CR5), not by the ranked leaders only.

Overview
What this landscape covers
This landscape tracks 228 patent families at the intersection of magnesium and Mg alloy compositions with powder metallurgy processing — spray deposition, powder compaction, and spark plasma sintering — filed between 2015 and mid-2026. The search combines alloy-family text terms with process-specific keywords and IPC classes spanning B22F (powder metallurgy), C22C (alloys) and B22F1 (special metal powder treatments), so it captures composition claims and processing claims together rather than either in isolation.
Filing activity peaked in 2020 and has since declined, with the most recent full year showing a fraction of peak-year volume. Because publication typically lags filing by around 18 months, the last one to two years in any trend line will understate true filing activity — treat the tail as a floor, not a ceiling.

The Numbers
Filing trend and technology composition
Two views of the same 228 families: how filing volume has moved year over year, and which IPC subclasses carry the claim density.
A field past its filing peak
Filings ran from 15 in 2017 to a peak of 16 in 2020, then fell to 4 by the 2022 midpoint and to 2 in the most recent (partial) year. That trajectory reads as flat-to-declining rather than an emerging technology gathering pace — new entrants are filing into a claim space that earlier work has already staked out.
Alloys and powder metallurgy anchor the field
C22C (alloys, 204 records) and B22F (powder metallurgy, 129) between them cover nearly the whole corpus, with C22F (non-ferrous treatment, 59) and B22D (casting, 48) as secondary processing routes. A61L (sterilising/biomedical, 12), C21D (heat treatment, 9) and C22B (extraction/refining, 9) are thin by comparison — these are the branches with room left to claim.
Shares are the percentage of the 228 records in scope. A patent can carry several IPC classes, so the shares add up to more than 100%.

Representative Filing
US11131007B1 — Boron nitride nanotube-magnesium alloy composites
THE FLORIDA INTERNATIONAL UNIVERSITY BOARD OF TRUSTEES
Boron nitride nanotube (BNNT)-magnesium (Mg) alloy composites and methods of fabricating the same are provided. The BNNT-Mg alloy composites can have a sandwich structure and can be fabricated by high-pressure spark plasma sintering. A mat of BNNTs can be sputter-coated with Mg, and then sandwiched between Mg alloy particles, followed by a sintering step. The BNNTs can include a hexagonal boron nitride phase.Filed by The Florida International University Board of Trustees, granted 2021-09-28. It illustrates how reinforcement-phase claims (BNNT mats, sputter coating, sandwich architecture) sit alongside the more conventional composition and sintering-parameter claims that dominate the older, most-cited art.

Citation counts are pulled from within this searched corpus and skew toward older filings simply because they have had longer to accumulate citations — read them as a signal of influence on later work, not of present-day 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 data means for a filing decision
Four read-outs from the corpus that matter more than the raw counts on their own.
Filing momentum
16 → 2
peak (2020) to latest year
The rush has already happened
Filing volume peaked in 2020 and has fallen every measured period since, down to 2 in the most recent partial year. New composition and sintering-parameter claims are landing on top of a decade of prior art rather than opening fresh ground.
Interpret the final one to two years as understated due to publication lag.
Geographic concentration
66 / 53 / 34
China / US / EPO filings
Three offices carry most of the activity
China (66), the United States (53) and the EPO (34) account for the bulk of receiving-office filings, with Japan (27), WIPO (13) and Canada (9) trailing. Freedom-to-operate work should prioritise these three jurisdictions first.
WIPO PCT filings (13) suggest limited multi-jurisdiction strategy relative to direct national filing.
Technology concentration
204 & 129
C22C and B22F record counts
Composition claims outnumber process claims
C22C (alloy composition) records outnumber B22F (powder metallurgy process) records by a wide margin, meaning composition space is more heavily claimed than the processing routes used to realise it — process innovation may be the more open lane.
C21D heat treatment (9) and C22B extraction (9) remain comparatively thin.
Assignee activity
0 in latest year
across every leading assignee
No incumbent is currently pressing the advantage
Every leading assignee tracked here, including Korea Institute of Industrial Technology (KITECH) and Netherlands Organisation for Applied Scientific Research (TNO), shows zero filings in the latest year. Leadership positions were built earlier and are not being actively reinforced at present.
A new, active filer could contest category leadership without displacing a currently-filing incumbent.

Players
Who holds the ground, and where it's thin
Assignee activity is concentrated among a handful of research institutes and industrial labs, several of which have paired filings with named co-inventors or partner organisations — but none of them is filing in the most recent tracked year.
Research institute cluster
4 co-filings
strongest co-assignee pair
Institute-led filing with named co-inventors
Korea Institute of Industrial Technology (KITECH) (Korea Institute of Industrial Technology) and EMK GmbH form the strongest co-assignee pair in the dataset at 4 shared filings, a pattern of institute-plus-partner filing repeated with Netherlands Organisation for Applied Scientific Research (TNO) and its named co-inventors.
10 co-assignee pairs total across the corpus.
Dormant leadership
0 in latest year
for every top assignee
Rankings reflect history, not current pace
None of the assignees appearing at the top of the ranking — including Tervis Co., Ltd., Lankheenden Technology Co. and Baker Hughes Holdings LLC — filed in the most recent year, so the current ranking is a record of past investment rather than active competitive pressure.
Check filing recency, not just cumulative count, before treating a name as a live competitor.
Biomedical niche
12 records
A61L subclass
A small, distinct biomedical thread
A61L (sterilising/biomedical) filings, exemplified by porous magnesium implant claims, form a small but distinct thread separate from the structural-alloy mainstream — a niche worth tracking separately from bulk-alloy competitors.
Only 12 records, versus 204 in the core C22C alloy class.

What's Next
Where to take this
The dataset points to specific next steps depending on whether the goal is freedom-to-operate, competitive tracking, or new filing strategy.
Run a freedom-to-operate check on process claims
Composition claims (C22C) are far denser than process claims (B22F), so a new sintering-parameter or reinforcement-phase approach is more likely to clear than a new alloy composition.

Check assignee activity in EurekaWatch the thin branches
A61L biomedical and C21D heat-treatment records are a fraction of the C22C core — these branches carry less prior art per claim and are worth a closer read before committing to a filing strategy.

FAQ
Common questions about this landscape
This landscape tracks 228 patent families filed between 2015 and mid-2026, drawn from a search combining magnesium/Mg-alloy composition terms with powder metallurgy process terms across IPC classes B22F, C22C and B22F1. Families, rather than raw document counts, are used because they neutralise duplicate filings across jurisdictions and continuation applications from the same underlying invention. The true figure for the most recent one to two years is understated because of the roughly 18-month lag between filing and publication.
No — filing peaked in 2020 at 16 records and has declined since, dropping to 4 by the 2022 midpoint and to 2 in the latest partial year. That pattern indicates a field where the core claim space has largely been staked out rather than one in an active growth phase. New entrants should expect to file into dense prior art on alloy composition in particular, since C22C accounts for the largest single share of records.
Leadership in this corpus is held by a mix of research institutes and industrial labs, including Korea Institute of Industrial Technology (KITECH) (Korea Institute of Industrial Technology) and Netherlands Organisation for Applied Scientific Research (TNO), both of which also show co-assignee filing patterns with partner organisations. However, none of the top-ranked assignees filed in the most recent tracked year, so the ranking reflects historical investment rather than current competitive activity. Anyone tracking this space competitively should check filing recency alongside cumulative rank.
The thinner IPC branches — A61L (sterilising/biomedical, 12 records), C21D (heat treatment, 9) and C22B (extraction/refining, 9) — carry far less claim density than the core C22C alloy composition class (204 records) or B22F powder metallurgy processing (129). Process-side innovations such as spark plasma sintering parameter control, reinforcement-phase sintering with materials like boron nitride nanotubes, and post-sintering heat treatment combinations are comparatively under-claimed relative to bulk alloy composition claims.
US11131007B1, assigned to The Florida International University Board of Trustees and granted in 2021, covers boron nitride nanotube (BNNT)-magnesium alloy composites with a sandwich structure, fabricated by sputter-coating a BNNT mat with magnesium, sandwiching it between magnesium alloy particles, and consolidating via high-pressure spark plasma sintering. It is a specific reinforcement-phase and process combination rather than a broad composition or generic sintering claim. Work using different reinforcement phases, different sandwich architectures, or different consolidation methods would need a separate infringement analysis rather than being automatically blocked by it.
