Permeable Pavement Systems Patents: Leaders & White Space 2026
Permeable pavement systems patents: who is filing, and where the claim space is still open
One clear leader, then a long tail. The top assignee holds 44 filings against a fifth-place count of 5 and a tenth-place count of 2, across 48 ranked companies. Filings peaked at 30 in 2017 and the tracked complete-year window shows 8 filings in 2021 falling to 5 in 2024, a -38% move. 2025 and 2026 figures are still incomplete due to publication lag and are not evidence of a further decline.

Common questions on permeable pavement patents
Who holds the most patents on permeable pavement systems?
In this 99-record dataset, one assignee leads clearly with 44 filings, well ahead of the fifth-ranked filer at 5 and tenth-ranked at 2, across a ranking of 48 companies. That leader’s representative filing applies cured carbon fiber composite material within a layered permeable pavement structure, an aerospace-materials approach rather than a traditional paving-industry one. Below the leader, filing counts drop quickly, meaning most other assignees in the ranking hold only a handful of records each.
Is filing activity in permeable pavement patents increasing or declining?
Filing peaked in 2017 at 30 records, and the last complete comparison window, 2021 to 2024, shows a decline from 8 to 5 filings, a -38% move. Counts for 2025 and 2026 appear lower still, but publication typically lags filing by around 18 months, so those most recent years are undercounted rather than genuinely quiet. The reliable read is the 2021-2024 decline, not the raw tail of the chart.
What technology areas do permeable pavement patents actually cover?
Roads-and-pavements structural claims (IPC class E01C) appear in 53.5% of the 99 records, making it the dominant category by a wide margin. Cement and ceramics materials claims (C04B) follow at 29.3%, with chemical/physical process claims (B01J) at 21.2% and water treatment (C02F) at 16.2%. Filtration, polymer processing and sewerage classes each sit at 14.1% or below, indicating that structural and materials claims are far more heavily filed than water-science or maintenance-technology claims.
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 Permeable Pavement Systems 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.
