Grain Aeration Patents: Top Companies & Filing Trends 2026
Grain Aeration and Silo Temperature Management Patents
81.4% of all 59 records in scope sit with just five assignees, and 94.9% with ten — this is a field with a settled top tier and almost no room left in the crowded middle. Filings ran at zero in 2017, climbed to a peak of 10 in 2019, and by the last complete three-year window fell from 3 filings in 2021 to 0 in 2024 — a -100% swing. That is a sharp drop from peak activity rather than a steady decline, and it leaves open whether renewed interest since has yet to clear the publication lag.

Common questions about this landscape
Who holds the most patents in grain aeration and silo temperature management?
One assignee leads with 16 of the 59 records in scope, well ahead of the rest of the field — fifth place holds only 3 records and tenth place just 1. The top five assignees combined account for 81.4% of all records, and the top ten for 94.9%, so this is a field with a clear leading tier rather than an even spread. Anyone doing competitive tracking should focus first on that leader’s specific claims rather than assume a fragmented market.
Is patent filing activity in grain aeration growing or slowing?
Filings peaked at 10 in 2019 and then pulled back sharply, falling from 3 in 2021 to 0 in 2024 in the last three-year span treated as complete data — a -100% change. Because publication lags filing by roughly 18 months, the years since 2024 are still filling in and should not yet be read as continued decline. The honest read is that the field cooled significantly from its 2019 high point, with the most recent trajectory still unclear.
What technology areas dominate the patent claims in this field?
Drying-related claims under IPC class F26B appear on 79.7% of the 59 records, making it by far the largest technology category. Business and data-processing claims (G06Q) follow at 47.5% and crop-processing claims (A01F) at 40.7%, reflecting how much of this field now involves monitoring software layered onto physical drying equipment. Ventilation-specific claims (F24F) and specialised storage-structure claims (E04H) are comparatively rare, at 8.5% and 5.1% respectively.
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.
