Epoxy Resin Additive Manufacturing Patent Landscape 2026
Only 16 families total. this is a narrow, low-density claim space, not a crowded one — filing here still means occupying open ground. Activity was flat at zero through 2017, built to a peak of four families in 2021, and the 2022 midpoint of three families indicates the growth phase has already passed rather than being mid-climb. The most recent year, 2026, is partial and should not be read as a drop-off.

Common questions about this landscape
How many patents exist for epoxy resin additive manufacturing?
The tracked dataset contains 16 published patent families filed between 2015 and the 2026 cut-off, covering IPC classifications for additive manufacturing (B33Y70, B29C64) and epoxy condensation chemistry (C08G59). That is a small field by patent-landscape standards, meaning claim space is not heavily occupied. Because publication lags filing by roughly 18 months, the true count for 2025-2026 filings is understated in any dataset pulled today.
Who holds the most influential patents in epoxy 3D printing?
Lawrence Livermore National Security, LLC holds the two most-cited records in this dataset: US20180243988A1 (cited 22 times) and US9944016B2 (cited 19 times), both covering rapid thermal/UV curing epoxy resin for carbon-fibre-reinforced additive manufacturing. A third Livermore-linked family, US9862140B2, on short and mixed fibre-reinforced polymer printing, is also among the most-cited. No other assignee in the set approaches that citation density, though citation counts favour older filings and should be read as a signal of early influence rather than current market weight.
Is the epoxy resin additive manufacturing patent space crowded?
No — with only 16 total families across more than a decade, this is a comparatively open field. Filing activity peaked in 2021 at four families in a single year, and the 2022 midpoint of three suggests the pace has since leveled rather than accelerated. The technology composition is also spread across eight IPC subclasses rather than concentrated in one, which points to a field still being defined rather than one with settled, dominant claim positions.
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 Epoxy Resin Additive Manufacturing 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.
