Mobile Crane Patents: Top Companies & Filing Trends 2026
Mobile crane structure and stability patents: who leads, and where the claim space is still open
Concentrated at the top. The five most active filers account for 61.2% of all 250 records in scope, and the top ten reach 76.0% — a small group has staked out most of the core claim space. Filings peaked at 41 in 2018, the busiest year in the window. The 2021-to-2024 span — the most recent stretch that can be treated as complete — shows filings rising from 6 to 8, a 33% increase; the tapering shown for 2025 and 2026 reflects publication lag rather than a real drop in filing.

Common questions about this landscape
Who holds the most mobile crane stability patents?
The dataset shows a concentrated leader board: the top-ranked assignee holds 61 records against 15 for fifth place, and the five most active filers together hold 61.2% of all 250 records in scope. This points to a small group of established crane manufacturers who have filed sustained programmes around boom, outrigger and load-moment control art rather than one-off filings. Anyone assessing freedom to operate should treat that top group as the baseline prior art to clear first.
Is the mobile crane patent field still growing?
Yes, based on the most recent years that can be treated as complete: filings rose from 6 in 2021 to 8 in 2024, a 33% increase. The peak year on record so far is 2018 at 41 filings, so activity has been uneven rather than steadily climbing. Figures for 2025 and 2026 look lower only because publication typically lags filing by about 18 months, not because filing has slowed.
What technology areas overlap most with mobile crane stability claims?
Beyond the core B66C crane and hoist class, which covers 75.2% of the 250 records, the next largest overlaps are B25J manipulators and robotics at 24.4% and G05B control and regulating systems at 15.6%. G01S positioning and radar/sonar classes appear in 12.0% of records. This shows that modern stability claims frequently combine mechanical crane structure with sensing and control logic rather than sitting in a purely mechanical category.
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 Mobile Crane Structure and Stability 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.
