Upper Limb Exoskeleton Patents: Who Leads, Where the Gaps Are 2026
Upper Limb Rehabilitation Exoskeleton Patents: Filing Trends and Leaders
71.2% of all 59 records sit with just five assignees — this is a field with a narrow leadership group, not a fragmented one. Filings peaked at seven records in 2018, dipped, then rose again, with 2021 to 2024 showing a documented +200% increase (1 to 3 records). Treat 2025 and 2026 as undercounts: publication typically lags filing by around 18 months, so recent years will keep filling in.

Common questions about upper limb exoskeleton patents
Who holds the most patents in upper limb rehabilitation exoskeletons?
The dataset’s leading assignee holds 12 of the 59 records in scope, noticeably ahead of the fifth-ranked assignee at 5 records. The top five assignees together account for 71.2% of all records, and the top ten reach 98.3%, meaning the field’s claim territory is dominated by a small group rather than spread evenly across the 30 ranked assignees. Anyone entering this space should map their planned claims against that top group first, since they cover nearly the entire published record set.
Is the upper limb exoskeleton patent field growing or slowing down?
Filings grew from 1 to 3 records between 2021 and 2024, a documented +200% increase over that span, which is the most recent period the data treats as complete. Figures for 2025 and 2026 appear lower, but that reflects the roughly 18-month lag between filing and publication rather than an actual slowdown. The honest read is renewed growth through 2024, with the most recent two years still filling in.
Which patent classes cover upper limb exoskeleton technology?
A61H, physical therapy and massage apparatus, appears in 74.6% of the 59 records and is the dominant class. B25J, manipulators and robots, follows at 44.1%, and A61F, implants and prostheses, at 39.0%. Because a single record can carry several IPC codes, these percentages add up to more than 100% — the useful reading is relative weight, not a partition of the dataset.
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 Upper Limb Rehabilitation Exoskeletons 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.
