Self-Healing Concrete Materials Patent Snapshot 2026
The self-healing concrete materials patent space is small and highly fragmented, with 25 patent families in scope and no single applicant holding more than 2 patent records. Filing activity has accelerated sharply since 2023, driven almost entirely by Indian academic institutions and individual inventors, with C04B (ceramics and cement) as the dominant technology class.
An emerging, India-dominated field with no dominant corporate incumbent
The visible assignees — including Vanjari Kalyani P, Bhadane Jagadish Prasad P, Kame Ganesh S, Mulay Hrishikesh U, and several peers — each hold 2 patent records, reflecting a flat, decentralized visible assignee structure with no incumbent commanding a meaningful portfolio advantage.
The top five filers account for 16% of the ranked applicants visible in this query’ combined total, confirming low concentration. The field lacks the tier-gap typically seen in mature technology domains; no applicant has yet separated from the pack.

The leaders’ positions imply that barriers to entry through patent exclusivity are currently low. An organization entering with even a modest, well-targeted filing program could rapidly reach a leading position by patent-record count.
The most recent 18–24 months of filings are subject to publication lag and likely under-represent actual inventive activity; the apparent acceleration in 2024–2026 should be read as a lower bound on true recent output. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
Sharp recent acceleration dominated by cement-chemistry filings
The annual filing trend and technology composition together reveal a field that was nearly dormant before 2023 and has since entered a rapid build-out phase, with C04B cement and ceramics chemistry absorbing virtually all filing volume.
Annual filing trend
Filings were negligible from 2017 through 2022 (one filing in 2017, zero in 2018–2022), then climbed to 1 in 2023, 6 in 2024, 8 in 2025, and 9 in 2026. Because the most recent 18–24 months are subject to publication lag, the 2025–2026 bars should be treated as provisional minimums rather than final counts.

C04B (ceramics, cement and refractories) accounts for all 25 patent records, establishing it as the unambiguous core class. Adjacent branches — C12N (microorganisms and genetic engineering) and G01N (material analysis and testing) each at 4 records, and E04G (scaffolding and formwork) at 3 — are present but markedly thinner, indicating that biological healing mechanisms and structural testing protocols remain comparatively under-explored relative to the cement-chemistry core.

One aspect of the present invention is directed to a method of preparing encapsulated ureolytic cells. This method includes blending freeze dried ureolytic cells and an aqueous solution to form a base mixture; mixing the base mixture with a silicate-forming compound to form a blend comprising silica encapsulated ureolytic cells; and freeze drying the silica… (excerpt from the patent abstract)

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.
Vanjari Kalyani P
Holds 2 patent records, all concentrated in C04B ceramics and cement subclasses (C04B 103, C04B 20, C04B 22). Momentum trend is marked as a new entrant, meaning all filings occurred in the most recent period with no prior portfolio history. Representative of the broader cohort of individual Indian inventors driving the current filing surge.
patent records: 2Aditya University
Holds 2 patent records, making it one of the few institutional applicants matching the leading individual inventors by count. Its presence signals that at least some Indian engineering institutions are beginning to formalize self-healing concrete research into IP filings rather than leaving output solely with individual inventors. Technology focus mirrors the corpus-wide concentration on C04B cement chemistry.
patent records: 2Frequently asked questions
The corpus in scope contains 25 patent families. This is a small dataset by patent-landscape standards, reflecting the early-stage nature of the field rather than a search gap.
India accounts for 24 of the 25 patent records in the corpus. The United States accounts for 1 record. No other jurisdictions appear in the evidence.
The top-ranked applicants — including Vanjari Kalyani P, Bhadane Jagadish Prasad P, Kame Ganesh S, Mulay Hrishikesh U, Kumavat Hemraj R, and Aditya University — each hold 2 patent records. There is no applicant with a larger portfolio in this corpus.
C04B (ceramics, cement and refractories) is the visible class, covering all 25 patent records. Adjacent classes such as C12N (microorganisms and genetic engineering) and G01N (material analysis and testing) each appear in 4 records.
The most-cited document — with 19 citations — concerns silica encapsulation of ureolytic bacteria for self-healing applications. The second most-cited (2 citations) addresses self-healing concrete for infrastructure durability. Patent numbers were not provided in the evidence for these specific titles.
Filing activity was negligible from 2017 through 2022, then accelerated: 1 filing in 2023, 6 in 2024, 8 in 2025, and 9 in 2026. The 2025–2026 figures are provisional due to publication lag and likely undercount actual activity. The multi-year trajectory is clearly upward from a very low base.

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.
