Wrought Superalloy Forging Patents: Who Leads, Where Filing Fell 2026
Wrought superalloy forging and disc manufacturing patents
41.4% concentration. The five leading filers account for 134 of 324 records in scope, with a long tail of single- and low-filing entrants behind them. Filings peaked at 34 in 2017 and have declined since; the 2021-to-2024 span shows a -75% drop (4 to 1 filings). Because publication typically lags filing by around 18 months, the final one or two years in this trend will fill in as more records publish and should not yet be read as a further decline.

Common questions on this landscape
Who are the leading patent holders in superalloy forging and disc manufacturing?
The ranked assignee list covers 70 companies, with the leader holding 44 of the 324 records in scope and the fifth-place company holding 13. This is a steep drop-off rather than a tightly bunched field, and the top 5 combined account for 41.4% of all records. The names sitting at the top are established aerospace engine and materials manufacturers with multi-decade filing histories in this space, rather than recent entrants.
Is patent filing activity in this field growing or shrinking?
Filing peaked in 2017 at 34 records and has declined since, with the 2021-to-2024 span showing a -75% drop from 4 filings to 1. That said, publication lags filing by roughly 18 months, so the most recent one or two years in any trend chart are always undercounted and should not be read as proof of an accelerating decline. The safest read is that activity has cooled substantially from its 2017 peak, with the very latest years still filling in.
Which technology areas are most heavily patented within this field?
Alloy composition (C22C, 46.6% of the 324 records), forging and hammering process (B21J, 42.0%) and non-ferrous metal treatment (C22F, 40.1%) are the three most heavily claimed IPC subclasses. Powder metallurgy, heat treatment, welding/brazing, turbine structures and forged metal products classes each sit well below 20% of records. Because a single record can carry several IPC codes, these percentages add up to more than 100% of the record total.
Disclaimer. This analysis is based on Patsnap Eureka data drawn from a limited snapshot of global patent records and is provided for general information and reference only. Patent data carries inherent limitations — recent filings are under-counted because of publication lag, counts may be on a record or family basis, classification and applicant-name data may contain errors or duplicates, and the underlying search query defines the scope shown — so the analysis may be incomplete or inaccurate and may not reflect the full technology landscape.
Nothing here is an exhaustive prior-art, novelty, freedom-to-operate or validity search, nor does it constitute legal, financial or professional advice, and it should not be relied upon as such. Verify independently and review with qualified patent and legal professionals before acting on it.
Method: Filing trend and technology composition. Derived from a Patsnap search on Wrought Superalloy Forging and Disc Manufacturing covering 2015–2026, data cut-off 2026-07-31.
