Giga Casting Patents: Who Leads, Where the Gaps Are 2026
- Alloys dominate the claim space. C22C alloy compositions appear in 63.2% of the 19 records in scope, far ahead of any structural or process class.
- One leader, a thin field behind it. The assignee ranking lists five companies; the leader holds 12 records against a fifth-place count of 1.
- Filing peaked in 2024, not yet in 2026. Activity rose from zero in 2017 to a peak of 12 records in 2024; the most recent year is still incomplete because of publication lag.
What this dataset covers
Giga casting replaces dozens of stamped and welded body panels with a single large aluminum structure, produced on high-tonnage die-casting machines in one shot. The patent activity tracked here spans alloy formulation, structural design, fastening and dimensional-control claims tied to that single-shot process, rather than casting machinery in general. Most records sit at the intersection of metallurgy and vehicle-body engineering, which is why alloy composition claims (C22C) outnumber every other class by a wide margin.
Nineteen published records is a small corpus. It is large enough to show where filing has concentrated and where it has not, but too small to support growth-rate claims or a precise concentration percentage across the field.
Filing trend and technology composition
Two views of the same 19 records: how filings moved year over year, and which IPC subclasses carry the claims.
Filing trend
Filings were flat at zero through 2017 and built up to a peak of 12 records in 2024. Because publication typically lags filing by around 18 months, the 2026 figure understates actual filing activity and should not be read as a decline.
IPC composition
C22C (alloys) covers 63.2% of the 19 records, with B62D (motor vehicles & steering), F16B (fasteners) and G05D (control of non-electric variables) each present in roughly 15-21% of records. Because a single record can carry several IPC classes, these shares add up to more than 100% of the record total — that overlap itself is informative: it shows how tightly alloy claims are bundled with structural and fastening claims in the same filings.
Shares are the percentage of the 19 records in scope. A patent can carry several IPC classes, so the shares add up to more than 100%.

Post-processing device of cast product
A post-processing device of a cast product is configured to post-process the cast product in which a plurality of components is integrated. In particular, the post-processing device may include i) a first press mold configured to trim cast scraps of the cast product and process at least one hole into the cast product, and ii) a second press mold configured to calibrate dimensions of the plurality of components and fasten hardware to the at least one hole.Filed by Hyundai Motor Company, published 2025-06-12. The claims sit downstream of the casting shot itself, covering trimming and dimensional calibration of an already-integrated multi-component casting.

Three findings that shape where a new filing would land relative to existing claims.
One company holds most of the ranked activity
The assignee ranking lists five companies; the leader's record count is twelve times the count held by the fifth-ranked company. That gap says more about who has been filing consistently than about the field being closed off, given the small size of the overall corpus.
Alloy claims are the densest single class
Nearly two-thirds of records in scope touch alloy composition (C22C), typically aluminum formulations tuned for large single-shot castings. Structural (B62D) and fastening (F16B) claims are each present in a much smaller share, suggesting alloy chemistry is where prior art is thickest.
Activity is recent and still building
Filings were at zero as recently as 2017 and rose to a peak of 12 records in 2024. With publication lagging filing by roughly 18 months, the 2026 count is not yet a reliable read on whether that peak has passed.
Eureka can read the same corpus for gaps instead of for coverage: under-claimed branches adjacent to giga casting for vehicle body structures, with the prior art for and against each one.
Who is filing
The ranking returned by this search covers five companies — it is the complete list the dataset produces, not a top-50 or top-100 cut.
The clear front-runner in this corpus
One assignee accounts for the largest share of records in the ranking, with filings spanning alloy and structural claims tied to large single-shot castings.
A single cross-filed pair
The dataset shows one co-assignee pairing between two Korean automakers, the only recorded instance of shared filing in this corpus.
Recent-year counts are flat across the board
Every ranked assignee shows zero recorded filings in the latest year, consistent with publication lag rather than an actual stop in filing activity.
| Assignee | Recent year | YoY |
|---|---|---|
| Uddeholms AB | 0 | -100% |
| Tesla, Inc. | 0 | — |
| Toyota Motor Corporation | 0 | — |
| Kia Corporation | 0 | — |
| Hyundai Motor Company | 0 | — |

Set a filing alert in EurekaCommon questions
Giga casting is a manufacturing process that produces a large single-piece aluminum structure, such as a vehicle underbody or front/rear structure, in one high-tonnage die-casting shot instead of assembling many stamped panels. It matters for patents because the process touches several distinct claim areas at once: the alloy formulation that has to flow and solidify without defects at that scale, the die and machine tonnage needed to cast it, and the structural design of the part itself. This dataset shows alloy composition claims are currently the densest of these areas, at 63.2% of the 19 records in scope.
The assignee ranking returned by this search lists five companies, with the leading assignee holding twelve records against a fifth-place count of one. That is a steep gap within a small ranked set, not a statement about the whole field, since the ranking only covers five companies and 19 records total. A freedom-to-operate review should still look at the leader's claims first given that gap.
Filings rose from zero in 2017 to a peak of 12 records in 2024, showing the technology only became a filing priority relatively recently. The dataset does not support a growth-rate figure because fewer than four complete years remain once publication lag is accounted for. The 2026 figure in particular should be read as incomplete rather than as a drop-off.
Relative to the dense alloy composition claims, branches like in-die dimensional correction, shot-weight process control and post-cast trim tooling carry far fewer records in this dataset. The representative Hyundai record on post-processing of cast products is one of the few filings addressing what happens to the part after the casting shot itself. A first claim in these areas would likely center on a specific control method or tooling step rather than on alloy chemistry, where prior art is thicker.
US20250187069A1, assigned to Hyundai Motor Company and published 2025-06-12, covers a post-processing device with a first press mold for trimming cast scraps and forming holes, and a second press mold for calibrating dimensions and fastening hardware. It blocks that specific two-stage trim-and-calibrate tooling sequence applied to an already-integrated multi-component casting, not the casting process itself or alloy formulations used in it. Someone designing a different post-processing sequence, or working upstream at the casting stage, would not necessarily be blocked by this claim, but a direct freedom-to-operate check against its exact claim language is still advisable before building similar trim tooling.

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.
