High Voltage Systems for Off Highway Patents: Leaders & Trends 2026
High voltage systems patents for off-highway electrification
60.0% concentration. The top 5 of 23 ranked assignees account for 39 of the 65 records in scope — filing is concentrated at the top with a long tail below. Filings climbed from 4 in 2021 to a peak of 9 in 2024 (+125% over that span). 2017 opened at zero recorded filings; treat 2025 and 2026 as undercounted given publication lag.

Common questions about this landscape
Who holds the most patents on high voltage interlock and harness systems for off-highway vehicles?
Filing in this dataset is concentrated: the leading assignee holds 20 of the 65 records in scope, and the top 5 of 23 ranked assignees together hold 39 records, or 60.0% of the field. That leaves a long tail below tenth place made up of assignees with only a handful of filings each. Anyone assessing freedom to operate should treat the leader’s portfolio as the first stop, then check the long tail for narrower but still-relevant claims.
Is patent filing in this area growing or slowing down?
Recorded filings grew from 4 in 2021 to a peak of 9 in 2024, a +125% increase over that span, which points to genuine growth through the last complete filing year. The 2025 and 2026 figures look lower, but publication typically lags filing by around 18 months, so those recent years are still filling in rather than showing an actual decline. Judge momentum against 2024, not against the most recent data point.
Which technology areas carry the densest patent coverage in high voltage vehicle systems?
B60L, covering electric vehicle propulsion, appears in 49.2% of the 65 records in scope, making it the single most-claimed area. B60K vehicle propulsion and drive, and H01M batteries and cells, each sit at 30.8%, indicating dense coverage across the drivetrain and battery interface. Connector and accessory classes such as H01R and B60R sit lower at 23.1% each, which is a useful signal for where claim space is comparatively less occupied.
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 High Voltage Systems for Off Highway 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.
