Tank Gauging Patents: Who Leads, Where the Gaps Are 2026
Tank Gauging and Inventory Management Patents
74.6% concentration. The top five assignees hold 53 of the 71 records in scope, leaving a thin tail of single- and double-filing entrants. Filings peaked at 15 in 2019, the highest single year in the dataset, before settling into a lower but recovering pattern — 1 filing in 2021 rising to 2 in 2024, a +100% increase over that span. 2025 and 2026 figures are still filling in under the publication lag and should not be read as a slowdown.

Frequently asked questions
Who are the leading patent holders in tank gauging and inventory management?
The dataset ranks 19 assignees across 71 records, with a single leader holding 20 records — well ahead of fifth place at 5 and tenth place at 2. The top five assignees combined hold 53 records, or 74.6% of all records in scope, and the top ten extend that to 95.8%. This means the field is concentrated at the top, with a long tail of assignees holding only one or two records each, rather than an evenly distributed field.
Is patent filing activity in tank gauging increasing or decreasing?
Filing peaked at 15 records in 2019, the highest single year in the dataset, then fell to a low point before recovering. Using the most recent years that can be treated as complete, filings rose from 1 in 2021 to 2 in 2024, a 100% increase over that span. Figures for 2025 and 2026 are still incomplete because publication typically lags filing by around eighteen months, so recent-year counts should not be read as a decline.
What technologies dominate tank gauging patent claims?
Flow, level and volume measuring (IPC class G01F) covers 40.8% of the 71 records, making it the largest single category, followed by dispensing liquids (B67D) at 33.8%. Radar, sonar and positioning (G01S) accounts for 14.1%, reflecting the role of radar-based level sensing in the field. Business-data processing (G06Q) and digital transmission (H04L) each sit at only 8.5%, indicating the data-integration side of tank gauging carries comparatively fewer claims than the core measurement hardware.
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 Tank Gauging and Inventory Management 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.
