Solids and Silo Level Measurement Patents: Leader, Then a Long Tail 2026
Solids and Silo Level Measurement Patents: Who Holds the Ground
One assignee accounts for 17 of 26 records in scope, with the top five combined reaching 96.2% of all filings — this field is not a contest among many players. Filings peaked at 6 in 2017 and have not returned to that level. With fewer than four complete years once the roughly 18-month publication lag is accounted for, no growth rate can be stated reliably from this trend alone; treat the latest years as undercounted rather than declining.

Common questions on this landscape
Who holds the most patents in solids and silo level measurement?
One assignee leads with 17 of the 26 records in scope, and the top five assignees together account for 96.2% of all records. That means the field is dominated by a single active filer in storage and blending systems, with the remaining assignees each holding a small number of records. Anyone entering this space should study the leader’s claim scope closely before drafting, since almost all prior art of consequence traces back to that one filer.
Is silo level measurement patent activity growing or slowing down?
The filing trend peaked in 2017 at 6 records and has not matched that level in any year since, through the 2026 data cut-off. Because publication typically lags actual filing by around 18 months, the most recent years in any dataset understate real activity, so a firm growth or decline rate cannot be stated from this trend alone. What can be said is that no second wave of filing has appeared since the 2017 peak.
What technology areas dominate solids and silo level measurement patents?
Mixing and stirring (B01F) and containers and packaging (B65D) each appear in 57.7% of the 26 records in scope, making them the two largest IPC subclasses. Earth and rock drilling (E21B) and conveying/material handling (B65G) follow at 38.5% and 34.6% respectively. Dedicated flow, level and volume measurement claims (G01F) appear in only 30.8% of records, indicating that most patents treat level sensing as one function inside a larger storage or handling system rather than as a standalone measurement invention.
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.
