Adaptive Radiotherapy Patents: Who Leads, Where the Gaps Are 2026
Adaptive Radiotherapy Workflow Patents: who holds the claim space
58.9% of all 151 records sit with just five assignees, while the ranked leader alone holds 34 — filing is concentrated, not fragmented. Filings peaked in 2019 at 33 records, then cooled before rising again: 2021 to 2024 grew from 5 to 11 records, a 120% increase over that three-year span. 2025 and 2026 figures are still incomplete because publication typically lags filing by around 18 months, so the most recent two years should not be read as a slowdown.

Common questions about this patent landscape
Who holds the most adaptive radiotherapy workflow patents?
Filing in this dataset is concentrated at the top: the five leading assignees together account for 58.9% of all 151 records in scope, and the ten leading assignees account for 82.1%. The single leader holds 34 records, well ahead of the fifth-place assignee at 8 and tenth place at 6. That pattern means a small group of medical-device and imaging companies, alongside a few university research groups, set most of the claim language other filers have to work around.
What does ‘adaptive radiotherapy’ cover in patent search terms?
In this dataset the search terms combine core adaptive-therapy concepts — online adaptation, adaptive replanning — with the technical mechanisms that make adaptation possible: contour propagation, dose accumulation, plan approval time, anatomy change detection, automation level and staffing model. That combination is why the technology composition leans heavily on A61N (electrotherapy and radiation therapy, 64.2% of records) and G06T (image processing, 47.7%), since most adaptive workflows are built around re-imaging plus dose recalculation.
Is the adaptive radiotherapy patent field still growing?
The filing trend shows a peak of 33 records in 2019, a subsequent cooling, then renewed growth from 2021 to 2024 — 5 records up to 11, a 120% increase over that span. Figures for 2025 and 2026 are still filling in because publication lags filing by roughly 18 months, so those most recent years understate actual filing activity rather than indicating a decline. Treat the 2021-2024 window as the most reliable recent signal.
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 Adaptive Radiotherapy Workflows 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.
