Patent Landscape · SuperalloysNickel Superalloy Powder for Additive Manufacturing: Patents, Leading Filers and Where Claims Are Thin
- 56.0% of all 1,186 records sit with just five assignees, so most freedom-to-operate questions in this field resolve to a small set of portfolios.
- Filings peaked in 2017 at 52 and the tracked 2021→2024 span shows a 38% pullback — read the final years as incomplete rather than declining, since publication lags filing by about 18 months.
- Powder metallurgy (B22F) and alloys (C22C) each cover over 42% of records, while casting (B22D) sits under 9% — a gap that points to underused claim space around post-atomization processing.

Leading Jurisdiction
Filing growth compares 2021 (13 records) with 2024 (8) — 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 1,186 records in scope (CR5), not by the ranked leaders only.

Overview
What this landscape covers
Nickel superalloy powder for additive manufacturing sits at the intersection of alloy chemistry and powder-bed processing: how a gas-atomized nickel-base powder behaves during laser or electron-beam melting, how satellite particles and oxygen pickup are controlled, and how a build survives hot cracking and repeated powder reuse. The search set pulls 1,186 published records filed or published between 2015 and mid-2026 that combine superalloy powder language with process-specific terms like hot isostatic pressing and build parameter window.
The scope favours documents that tie alloy composition claims to a specific manufacturing step, rather than general superalloy chemistry or general additive manufacturing. That combination is what separates this set from a broader powder-metallurgy or general superalloy search, and it is why the assignee list is dominated by aerospace-engine and specialty-metals firms rather than generic AM machine builders.

The Data
Filing trend and technology composition
Two views of the same 1,186-record set: how filing activity has moved year over year, and how records distribute across IPC subclasses. Because a single record can carry several IPC codes, the class shares below sum to more than 100% of the record total.
Filing activity, 2015-2026
Filings rose to a peak of 52 in 2017, then eased. The tracked 2021-to-2024 span (13 down to 8) works out to a -38% move — treat 2025 and 2026 as still filling in given the usual 18-month lag between filing and publication, not as evidence of a continued slide.
IPC subclass distribution
C22C (alloys) and B22F (powder metallurgy) each anchor over 42% of the 1,186 records, confirming this is fundamentally an alloy-composition-meets-powder-process field. F01D (turbines) at 22.3% shows how much of the filing is end-use-specific to turbine hardware rather than powder production in the abstract, while B22D (casting) at 8.9% and B23P (metal working) at 11.6% mark thinner, more open ground.
Shares are the percentage of the 1,186 records in scope. A patent can carry several IPC classes, so the shares add up to more than 100%.

Representative Filing
US20130142686A1 — Endplate for hot isostatic pressing canister, hot isostatic pressing canister, and hot isostatic pressing method
ATI PROPERTIES, INC.
An endplate for a hot isostatic pressing canister comprises a central region, and a main region extending radially from the central region and terminating in a corner about a periphery of the endplate. The thickness of the endplate increases along the main region, from the central region to the corner, defining a taper angle. The corner includes an inner surface comprising a radiused portion by which the main region smoothly transitions into the lip. A hot isostatic pressing canister including at least one of the endplates also is disclosed, along with a method of hot isostatic pressing a metallurgical powder using the hot isostatic canister.Filed by ATI Properties, Inc. This is a mechanical-hardware claim on canister geometry rather than on alloy chemistry or powder process parameters — worth checking separately from composition-based filings.

What the numbers mean for filing strategy
The concentration and composition figures point to a field where the top of the ranking is settled but several process-adjacent branches remain lightly claimed.
Concentration
56.0% of 1,186 records
held by the top five assignees
The top of the field is settled
More than half of all records in scope belong to five assignees, and the top ten extend that to 72.6%. A new entrant filing composition or process claims here is filing into occupied ground and should expect to design around, not around, the leaders' existing claim sets.
Top 10 combined: 861 records
Filing momentum
52 filings in 2017
the peak year on record
Activity has cooled from its 2017 high
The tracked 2021-to-2024 window shows filings moving from 13 to 8, a 38% pullback. Because publication trails filing by roughly 18 months, the last one to two years in the chart will fill in further and should not be read as the field going quiet.
2021: 13 → 2024: 8
Technology mix

C22C alloys vs B22D casting share
Alloy and powder classes dominate; casting lags
C22C and B22F each sit above 42% of the 1,186 records, confirming the field's centre of gravity is alloy chemistry paired with powder handling. B22D (casting) at 8.9% and B23P (metal working) at 11.6% are comparatively open, suggesting less-crowded claim space around post-build finishing and hybrid casting-plus-AM routes.

What's Next
Where to take this analysis
The dataset points to a field with a settled leadership tier and several specific process branches that remain lightly claimed. The next step is turning that into a filing or freedom-to-operate decision.
Map claims against the leader's portfolio
With one assignee holding 192 of 1,186 records, any new filing in alloy composition or atomization process should be checked against that portfolio first, not the field average.

FAQ
Common questions about this landscape
One assignee leads with 192 of the 1,186 records in scope, well ahead of the fifth-place holder at 81. The top five assignees together account for 56.0% of all records, and the top ten reach 72.6%, so the field is concentrated among a small number of aerospace-engine and specialty-metals firms. A new entrant should treat that leader's portfolio, not the field average, as the first freedom-to-operate check.
Filings peaked in 2017 at 52 and have eased since, with the tracked 2021-to-2024 window showing a move from 13 to 8, a 38% pullback. However, publication lags filing by roughly 18 months, so the most recent one to two years in any count will keep rising as more records publish. Treat any apparent recent decline with that lag in mind rather than as confirmed cooling.
Alloy composition (IPC class C22C) and powder metallurgy (B22F) each cover more than 42% of the 1,186 records, making them the field's core. Turbine and engine end-use claims (F01D) appear in 22.3% of records, reflecting how much of this filing is tied to specific engine hardware rather than powder production alone. Casting-related claims (B22D) sit under 9%, marking comparatively open ground.
US20130142686A1, assigned to ATI Properties, claims a specific endplate geometry for a hot isostatic pressing canister — a tapered, radiused design rather than an alloy composition or a powder process parameter. It also covers the canister itself and a HIP method using it. Anyone designing HIP tooling for superalloy powder consolidation should review this claim's geometric limitations specifically, since it does not block composition or atomization-parameter work.
Relative to the dominant alloy (C22C) and powder-metallurgy (B22F) classes above 42% each, casting (B22D, 8.9%) and general metal working (B23P, 11.6%) carry noticeably lower filing density. Specific process sub-areas such as powder reuse degradation limits, satellite particle mitigation and build parameter window transfer across machine platforms also show thinner coverage than core composition claims. These are reasonable starting points for a claim-drafting review before assuming the space is fully occupied.
