Electron Beam Curing Patents: Who Leads, Where the Gaps Are 2026
Electron Beam Curing Patents: Filing Trends, Leading Assignees and Open Claim Space
43.9% concentration. The top 5 of 48 ranked assignees hold 50 of the 114 records in scope — a leader at 19 filings followed by a fast-thinning field. Filings ran at 13 in 2017, the peak year so far, and the last fully comparable window — 2021 to 2024 — shows a 33% decline (3 to 2). Treat 2025 and 2026 figures as still filling in rather than as confirmed decline.

Questions practitioners ask about this field
Who holds the most electron beam curing patents?
One assignee leads the ranked field with 19 of the 114 records in scope, well ahead of the fifth-ranked assignee at 5 and the tenth-ranked at 4. The top 5 of 48 ranked assignees together account for 43.9% of all 114 records, and the top 10 account for 64.0%. Beyond that point the field thins into a long tail of companies holding only one or two families each, so most participants are not repeat filers.
Is electron beam curing patent activity growing or shrinking?
Filing peaked in 2017 at 13 published records and has cooled since; the most recent complete comparison, 2021 to 2024, shows a 33% decline from 3 to 2 records. Figures for 2025 and 2026 should not be read as confirming further decline, because publication typically lags actual filing by around 18 months and those years are still filling in. On the evidence available, the trend through 2024 points down rather than up.
What technology areas do electron beam curing patents cover?
Records are classified across several IPC subclasses because a single patent can carry more than one class. Polymer compositions (C08L) and coatings, paints and inks (C09D) are each present in 28.1% of the 114 records, with polymer processing (C08J) at 21.9% and layered products and laminates (B32B) at 21.1%. Coating processes (B05D), plastics shaping (B29C), adhesives (C09J) and polymer additives (C08K) each appear in a smaller but still notable share, showing the field’s claims concentrate in formulation and application rather than in the beam source itself.
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 Electron Beam Curing covering 2015–2026, data cut-off 2026-07-31.
