Casting Solidification Simulation Patents: Leaders & Trends 2026
Casting solidification simulation and defect patents: who holds the ground and where it opens up
One filer leads at 24 records, and the top 5 alone account for 53.0% of all 83 records in scope — a heavily concentrated field for a niche of this size. Filings ran from 6 in 2017 to a peak of 7 in 2020, then eased to 4 by 2021 and 3 by 2024 — a 25% decline over that complete-year span. 2025 and 2026 figures are still filling in under publication lag and should not be read as continued decline.

Common questions on this landscape
Who are the leading patent holders in casting solidification simulation?
The ranking covers 55 assignees across 83 records in this corpus, with one company holding 24 records well ahead of the rest of the field. The top 5 assignees combined account for 53.0% of all 83 records, so the field is concentrated at the top even though it includes over fifty named filers. Beyond the top five, the count drops sharply, with fifth place holding only 3 records and tenth place 2, leaving a long tail of single- or double-filing entrants.
Is patent filing in casting simulation growing or slowing down?
Filing peaked at 7 records in 2020 and has eased since, with the last complete comparison period, 2021 to 2024, down 25%. Because publication typically lags filing by around 18 months, the 2025 and 2026 counts in any trend chart are still incomplete and should not be read as evidence of continued decline. The honest read is a cooling trend through 2024, with the most recent two years not yet settled.
What does US7024342B1 cover and why does it matter here?
US7024342B1, titled ‘Thermal flow simulation for casting/molding processes’, is the most-cited record in this corpus at 161 citations, making it the single most influential prior-art reference for anyone filing on thermal-flow or shrinkage-porosity simulation methods. A closely related filing, WO2002003309A1, shares the same title and underlying approach and was filed by AEMP Corporation. New filings in this space are commonly examined against this pair, regardless of when they are actually drafted.
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.
