Grain Quality Sensing Patents: Leaders, Trends & White Space 2026
Grain Quality Sensing and Grading Patents: Who Holds the Claims
Three named assignees cover the entire ranked field, with the leader alone holding 26 of the tracked families. Filings opened at 4 in 2017, rose to a peak of 7 in 2018, and have since declined toward 0 in 2026 — though the most recent one to two years are understated because publication typically lags filing by around 18 months. Treat the tail as provisional rather than as a genuine drop-off in R&D activity.

Common questions on this landscape
Who are the leading patent holders in grain quality sensing and grading?
The assignee ranking for this scope returns just three named companies, and one of them holds 26 of the 41 records tracked. That degree of concentration in a small ranking means the field is easier to map for freedom-to-operate purposes than most sensing categories, but it also means a single dominant holder’s claims are worth reviewing closely before filing. All three assignees also co-appear on filings together, suggesting close commercial or corporate ties rather than fully independent development.
Is patent filing in grain quality sensing still growing?
Filing peaked at 7 records in 2018 and has declined toward 0 by 2026, but that decline should not be read at face value. Publication typically lags filing by around 18 months, so the last one to two years in any patent trend are understated by definition. There is not enough complete post-2018 data to state a reliable growth or decline rate, and none is claimed here.
What sensing technologies dominate the patent claims in this field?
Pictorial communication (H04N) and harvesting/mowing equipment (A01D) each appear in a majority of the 41 records in scope — 65.9% and 63.4% respectively — reflecting how much of the claimed technology is camera-based sensing mounted directly on combines and harvesters. Positioning and radar-style sensing (G01S) and image/data recognition (G06K, G06T) form the supporting machine-vision layer. Material analysis, weighing and conveying integration carry noticeably lighter coverage.
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 Grain Quality Sensing and Grading covering 2015–2026, data cut-off 2026-07-31. Counts reflect published records only and shift as new filings publish. Every share divides by all records in scope. Data: Patsnap Eureka. See the full landscape report.
