Self-Healing Concrete Foundation Patent Snapshot
Self-healing concrete foundation patenting is a nascent field with only 6 patent families in scope, dominated by academic and individual filers with no single organization holding more than 2 families. Activity is highly concentrated in India and China, with the field showing early signs of emergence rather than maturity.
Academic filers lead a fragmented, early-stage field
Wuhan University leads the ranking with 2 patent records, making it the sole applicant with more than one filing; all other ranked applicants hold a single record each.
The top five filers account for 35% of the combined total across the ranked applicants visible in this query, indicating a moderately fragmented top tier with no visible commercial owner. The roster is composed almost entirely of universities and individual researchers rather than construction or materials corporations.

The academic composition of the leader board suggests the technology is still in a research phase, with limited evidence of industrial players moving to secure broad portfolio positions. This creates both an openness for new entrants and uncertainty about which technical approaches will achieve commercial scale.
Filings from 2024 onward are subject to standard publication lag and likely under-represent actual recent activity; the apparent uptick in 2024–2025 should be read cautiously. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
Activity concentrated in cement chemistry and foundation engineering
The filing trend reveals a field that was essentially dormant before 2022 and has seen modest but notable activity from 2024 onward. The technology composition is anchored in cement and ceramics chemistry alongside foundation engineering, with several adjacent branches holding only a single record each.
Annual filing trend
No filings were recorded before 2022 in the evidence window; a single record appeared in 2022, followed by a cluster of three in 2024 and two in 2025. The 2024–2025 data should be treated as a floor rather than a ceiling given publication lag. The overall pattern suggests an emerging field, not an established one.

C04B (Ceramics, cement and refractories) is the visible IPC branch with 6 patent records, followed by E02D (Foundations and earth drilling) with 4 and G01N (Material analysis and testing) with 2. All other branches — including additive manufacturing, polymer additives, and roads — each carry a single record, indicating the core technical work is tightly focused on mix design and pile/foundation mechanics.

Ranked by total forward citations. Citation counts favour older and broadly cited patent families, and broad or adjacent patents may appear when they match the search scope. Treat this section as citation context, not as a curated list of the most topic-specific patents. Some patent titles may be shown in their original, non-English language where an accurate translation could not be guaranteed.
Assignee snapshot from the current evidence set
The applicants below are visible in this query result. Because the evidence set is relatively small, read this section as a directional snapshot rather than a full competitive ranking.
Wuhan University
Wuhan University holds 2 patent records — the largest share of any single applicant — with technical emphasis squarely on E02D subclasses covering pile foundations, retaining structures, and soil interaction. This structural-engineering focus differentiates it from the chemistry-oriented Indian filers. No momentum trend is available for Wuhan University in the recent-window data.
families: 2Fuzhou University
Fuzhou University enters the evidence window as a new entrant with 1 patent record, focusing on B28B (shaping of cement products) and C04B (cement formulation). As a new entrant, its trajectory is not yet established, but its manufacturing-process orientation complements rather than overlaps with Wuhan University’s structural approach, suggesting differentiated rather than competing positions.
families: 1Frequently asked questions
The evidence covers 6 patent families in scope. This is a very small corpus, consistent with a nascent field that has seen meaningful filing activity only since 2022.
Wuhan University leads with 2 patent records, focused on foundation and pile engineering subclasses under E02D. All other applicants in the ranked list hold a single record each.
India accounts for 4 patent records and China for 3, with a single WIPO (PCT) filing representing international coverage. No European or North American office filings appear in the evidence.
The current ranked applicants are almost entirely universities, engineering colleges, and individual inventors. One Chinese construction company appears in the list. No major construction materials corporation or infrastructure group appears in the top filers.
The two most-cited records in the evidence are both Chinese-language filings: one describing a frost-heave-resistant self-healing concrete pile, and one describing a functionally graded self-healing high-strength concrete pipe pile. Both relate to pile foundations specifically.
Additive manufacturing (B33Y) and polymer additive systems (C08K) each have only a single patent record in the corpus, representing the sparsest intersections with the core foundation and cement-chemistry claims. These branches have plausible technical rationale but minimal existing IP coverage.

Patent data carries inherent limitations: recent filings (typically the most recent 18–24 months) are under-counted due to standard publication lag; counts may be reported at either a patent-family or a patent-record basis and are not always directly comparable; classification, applicant-name, and citation data may contain errors, duplicates, or omissions; and the underlying search query defines and constrains the scope shown. As a result, the analysis may be incomplete or inaccurate and may not reflect the full technology landscape.
