Photopolymer Resin Formulation Patents: Leaders & Trends 2026
Photopolymer resin formulation patents: mapping who holds the vat photopolymerization chemistry
A three-way field. the assignee ranking returns just three companies against 13 published records — a small, tightly held corpus rather than a crowded one. Filings were absent in 2017, built toward a peak of 10 records in 2022, and taper toward the 2026 cut-off. Because publication typically lags filing by around 18 months, the most recent years in this trend are understated rather than a genuine drop-off in activity.

Common questions about photopolymer resin formulation patents
How many companies actually hold patents in photopolymer resin formulation?
The assignee ranking for this dataset returns three companies across 13 published records. This is the complete ranking the data endpoint returns, not a top-50 or top-100 cut, so it reflects a genuinely narrow field rather than a large industry where only the leaders were counted. One assignee holds the majority of the ranked records, with the remaining two holding smaller shares including a co-filed pair.
What is the most cited patent in this field and why does that matter?
The most-cited record describes dispersions of discrete carbon nanotubes for additive manufacturing, filed as a family spanning WIPO, Canadian and US applications. High citation counts inside a searched corpus tend to favour older filings that have simply had more time to accumulate citations, so this should be read as a signal of influence within the dataset rather than proof that the technology is still the most commercially relevant one today.
Why does the filing trend show a drop after 2022?
Filings peaked at 10 records in 2022 within this dataset and appear to decline afterward, but patent applications typically take around 18 months to publish after filing. That means the years closest to the 2026 data cut-off are systematically undercounted, and the apparent drop-off is more likely an artefact of publication timing than a real reduction in R&D activity.
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 Photopolymer Resin Formulation 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.
