UV Curable Ink Patents: Who Leads, Where the Gaps Are 2026
UV Curable Ink Formulation Patents
One assignee dominates the ranked field. the leader holds 35 records against a fifth-place assignee at 1, with no second cluster visible in this dataset. Filings rose to a peak of 9 in 2018, then the tracked 2021-to-2024 window shows a full -100% decline to zero. Treat 2025 and 2026 as undercounted rather than as evidence of a stalled field, since publication lag has not yet caught up with those filing years.

Common questions about UV curable ink patents
Who holds the most patents in UV curable ink formulation?
In this dataset, one assignee leads with 35 of the records captured in the ranking, well ahead of the next four ranked companies, one of which holds only 1 record. That gap suggests the field is shaped more by a single incumbent’s claim footprint than by a competitive cluster of similarly sized filers. Anyone assessing freedom to operate should start by reviewing that leader’s granted claims before looking at the smaller filers.
Is UV curable ink patent activity still growing?
Filing activity peaked at 9 records in 2018 and the tracked 2021-to-2024 window shows a complete -100% drop to zero filings. Because publication lags actual filing by roughly 18 months, the 2025 and 2026 figures in any dataset are undercounted and should not be read as proof the field has stopped. A fair read is that filing has contracted sharply through the last complete tracking window, with the most recent trend still uncertain.
Which technical claims dominate UV curable ink patents?
Coatings, paints and inks (IPC class C09D) appear in 87.0% of the 46 records in this landscape, far ahead of any other class. Addition-polymer chemistry (C08F) and polymer processing (C08J) trail at 17.4% and 13.0% respectively, and print-head-specific claims (B41J) and condensation-polymer chemistry (C08G) sit near 10-11%. This indicates most protected inventive activity is at the ink-formulation level rather than in adjacent monomer synthesis or printer hardware.
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 UV Curable Ink 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.
