Image-Guided Radiotherapy Patents: Top Companies & Trends 2026
Image-Guided Radiotherapy Patents: Who Leads and Where Filing Is Headed
Concentration at the top. The five leading assignees together hold 417 records — 28.6% of the 1,456 families in scope — while the ranked field runs 100 companies deep with a long tail below tenth place. Filings peaked at 148 records in 2017. On the last window that can be treated as complete, volume fell from 79 records in 2021 to 52 in 2024 — a 34% decline. Read 2025 and 2026 as still filling in rather than as confirmation of a continued fall.

Common questions about the image-guided radiotherapy patent landscape
Who are the leading patent holders in image-guided radiotherapy?
The dataset ranks 100 companies by filing volume, with the leading assignee holding 111 records against 1,456 total families in scope. The top five assignees combined account for 417 records, or 28.6% of the corpus, and the top ten reach 42.7%. Below tenth place, holdings drop off quickly into a long tail of companies with far fewer filings each, so the field is concentrated at the top but not dominated by a single player.
Is patent filing in image-guided radiotherapy growing or slowing?
Filing peaked at 148 records in 2017 and has declined since, falling from 79 records in 2021 to 52 in 2024 — a 34% drop over that three-year span. Figures for 2025 and 2026 look lower still, but publication typically lags actual filing by around 18 months, so those recent years are undercounted rather than necessarily reflecting a real stop in activity. The safest read is a cooling trend through 2024, with the most recent two years still incomplete.
What technology areas do most image-guided radiotherapy patents cover?
A61B (diagnosis and surgery) appears on 69.4% of the 1,456 records and A61N (electrotherapy and radiation therapy) on 43.0%, together anchoring most of the filing activity around patient positioning and radiation delivery hardware. Image data processing (G06T) covers 9.7% of records, and particle/radiation handling, dosimetry and implant-related classes each sit at single-digit shares. Because a single record can carry multiple IPC codes, these percentages add up to more than 100% and should be read as overlapping coverage, not a strict breakdown.
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.
