Pultrusion Patents: Who Leads, Where the Gaps Are 2026
Pultrusion and Continuous Profile Production Patents
Filing activity has cooled from its 2017 peak of 62 records, and the 2021→2024 span shows a -45% drop (22 to 12), a real decline once the 18-month publication lag is accounted for. Filings peaked at 62 in 2017. The comparable, publication-lag-adjusted window shows 22 records in 2021 falling to 12 in 2024 — a 45% decline over that three-year span. Years after 2024 will keep rising in the chart as publications catch up, so treat the tail as incomplete rather than as a continuation of the drop.

Common questions about pultrusion patents
Who are the leading patent holders in pultrusion technology?
The dataset’s assignee ranking covers 100 companies, with the leader holding 51 of the 1,043 records in scope. Ownership is fragmented rather than concentrated: the top 5 assignees combined account for only 19.7% of all records, and the top 10 for 32.5%. This means no single company controls the core claim space, and a competitive review needs to look well beyond the top few names to get a full picture.
Is pultrusion patent filing activity growing or slowing down?
Filing peaked in 2017 at 62 records and has since declined; the comparable 2021-to-2024 window shows a drop from 22 to 12 filings, a -45% change. Because patent publication lags filing by roughly 18 months, the most recent one to two years in any chart will look artificially low and should not be read as confirming the decline further. Based on the complete years available, the trend is a genuine cooling rather than a data artefact.
What technical areas dominate pultrusion patent claims?
Shaping-of-plastics claims under IPC class B29C appear in 52.4% of the 1,043 records, making it by far the most heavily claimed area, followed by polymer processing (C08J, 26.9%) and plastics preparation (B29B, 17.6%). Compositional classes covering additives, condensation polymers and polymer compositions each sit below 13% of records. This indicates that die design, pull mechanics and processing steps are more densely claimed than resin formulation or additive chemistry.
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 Pultrusion and Continuous Profile Production 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.
