Self-Healing Concrete Structural Use Patent Snapshot 2026
The formal patent corpus for self-healing concrete in structural applications is extremely small — just 3 patent families held by 3 distinct applicants across three jurisdictions — signalling a nascent, pre-competitive field. No single entity has established a dominant position, and the technology space remains almost entirely open to new entrants.
Three applicants share an evenly split, pre-competitive Snapshot
The corpus contains 3 patent families attributed to three applicants: Quantime Co., Ltd. (Korea), Drexel University (USA), and Sri Venkateswara College of Engineering & Technology (India). Each holds exactly one patent family, making concentration perfectly equal at this stage.
The top five filers account for 100% of the ranked applicants visible in this query’ combined total — in practice, all three known applicants are tied at the top with no tier gap between them. This symmetry reflects the field’s embryonic state rather than any entrenched competitive advantage.
| # | Applicant | Patent families | Share |
|---|---|---|---|
| 1 | Quantime Co., Ltd. | 1 | |
| 2 | Drexel University | 1 | |
| 3 | SRI VENKATESWARA COLLEGE OF ENG & TECH | 1 |
The leaders’ positions imply that no applicant has yet built a blocking portfolio or a defensible technology cluster. An organisation entering now with even a modest filing programme could rapidly establish a leading position.
All recorded activity clusters in 2025, which falls within the typical 18–24 month publication lag window; the corpus may therefore undercount recent filings that have not yet been published. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
All activity concentrated in 2025; cement-chemistry class dominates
The annual filing trend and the technology branch breakdown together reveal a field that has only just crossed the threshold of formal patent activity, with a single technology class accounting for all three families.
Annual filing trend
Zero filings appear from 2017 through 2024; all three families were filed or published in 2025. Because 2025 sits within the patent publication lag window, this spike should be read as the field’s first visible activity rather than a peak — additional filings from 2024–2025 may not yet have surfaced.

C04B (Ceramics, cement & refractories) covers all three families, confirming that work centres on cementitious matrix formulation. C09D (Coatings, paints & inks) and G01M (Testing machine & structural balance) each appear on one record, pointing to early-stage interest in surface-applied healing agents and structural performance measurement — both thin branches relative to the core.

Damage-responsive self-healing concrete
The present invention relates to concrete compositions and methods of making a concrete composition having self-healing properties, including a cementitious matrix impregnated with a plurality of biofibers, wherein the biofibers comprise: a polymer fiber core comprising one or more polymers selected from the group consisting of polyester, polyethylene… (excerpt from the patent abstract)
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.

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.
Quantime Co., Ltd.
Quantime Co., Ltd. holds 1 patent family concentrated entirely within the C04B ceramics and cement class, covering three distinct subclass codes (C04B 22, C04B 24, and C04B 28) — the broadest subclass spread among the three applicants. Applicant momentum data is not yet available for this entity, consistent with the corpus being limited to 2025 filings.
families: 1Drexel University
Drexel University holds 1 patent family with technology emphasis in C04B subclasses 16, 20, and 28 — the fibre and aggregate modification codes — suggesting a research focus on fibre-reinforced or aggregate-embedded self-healing mechanisms. As a US research university filing via WIPO PCT, it is the applicant most likely to pursue broader territorial coverage. Momentum data is evidence pending.
families: 1Frequently asked questions
The corpus contains 3 patent families. All three were filed or published in 2025, and no prior-year activity appears in the evidence from 2017 through 2024.
Three applicants are ranked equally at one patent family each: Quantime Co., Ltd. (South Korea), Drexel University (USA), and Sri Venkateswara College of Engineering & Technology (India). No single entity leads by count.
India, South Korea, and WIPO (PCT) each have one patent record. India is the lead office by filing count. Major markets such as the United States, China, and the European Union are not represented in the current corpus.
C04B (Ceramics, cement & refractories) covers all three patent families. C09D (Coatings, paints & inks) and G01M (Testing machine & structural balance) each appear on one record as secondary branches.
The evidence shows an extremely nascent corpus with no incumbent blocking portfolios, no detected co-filing consortia, and major commercial jurisdictions unrepresented. These factors collectively suggest wide open entry conditions, though any commercial assessment should also account for prior art in adjacent cement-chemistry literature beyond this specific corpus.
The concentration of all three families in 2025 coincides with the standard 18–24 month patent publication lag. The visible spike most likely represents the first wave of formal filings rather than a true peak; additional filings from the same period may not yet have been published.

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.
