Self-Healing Concrete Durability Patent Snapshot 2026
The patent corpus for self-healing concrete durability and sustainability is nascent, with only 4 patent families in scope and activity concentrated equally across four distinct filers in China and India. The field sits at a very early formation stage with no single dominant player, creating substantial space for new entrants with differentiated approaches.
A nascent field with four equally ranked filers and no dominant leader
The self-healing concrete durability and sustainability patent corpus currently comprises 4 patent families, distributed evenly among four applicants: Sona College of Technology, Swami Vivekananda University, Beijing Jinyu Concrete, and Northeast Forestry University — each holding 1 patent family.
Concentration is absolute at the top: the top five filers account for 100% of the ranked applicants visible in this query’ combined total, yet no single organization has established a meaningful lead. The tier structure is completely flat, with all active filers at parity.

The equal distribution among academic institutions and one industry player (Beijing Jinyu Concrete) suggests the field is still in exploratory research mode, with no organization yet executing a portfolio-building strategy. This is characteristic of a pre-commercial technology window.
Filing records for 2024–2026 should be treated as provisional, as patent applications typically take 18–24 months from filing to publication; the corpus total may understate actual recent activity. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
Activity emerged only in 2024, concentrated entirely within C04B ceramics and cement
The trend chart and technology composition together show a field at inception: zero recorded filings from 2017 through 2023, with the first families appearing in 2024 and 2025, and the highest count arriving in 2026. All four families fall under C04B (Ceramics, Cement & Refractories), leaving adjacent technology branches entirely unoccupied.
Annual filing trend
No activity is recorded from 2017 to 2023. One family each appears in 2024 and 2025, with two families in 2026. Given publication lag, the 2024–2026 figures should be read as a floor estimate; actual filed volume in recent years is likely higher than currently indexed.

All 4 patent families are classified under C04B (Ceramics, Cement & Refractories). The absence of filings in adjacent classes — such as those covering biological materials, structural monitoring, or polymer-based healing agents — indicates that the patented work to date addresses cement matrix formulation rather than system-level or biologically enabled healing mechanisms.

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.

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.
Sona College of Technology
Sona College of Technology holds 1 patent family, placing it at the top rank alongside the other three filers. Its technology focus within C04B covers aggregate and filler materials (C04B14), surface-modified constituents (C04B18), and processed inorganic components (C04B20), suggesting work on modified ingredient systems for self-healing cement matrices. No momentum trend data is available for this applicant in the current evidence.
families: 1Northeast Forestry University
Northeast Forestry University holds 1 patent family and is flagged as a new entrant in the applicant momentum data, indicating its filing arrived in the most recent period. Its C04B sub-focus spans mineral aggregates (C04B14), organic/natural constituents (C04B20), and hydraulic binders (C04B28), which is consistent with bio-based or wood-derived additive approaches to self-healing cementitious materials — a technically distinct angle from purely synthetic routes.
families: 1Frequently asked questions
The current corpus contains 4 patent families in scope. This is a very small corpus, consistent with an early-formation technology area where systematic patenting has only recently begun.
Four applicants each hold 1 patent family: Sona College of Technology, Swami Vivekananda University, Beijing Jinyu Concrete, and Northeast Forestry University. No single organization has established a portfolio lead.
Current filings are recorded in China (2 families) and India (2 families). No filings are recorded in the United States, Europe, Japan, or South Korea within this specific corpus.
All 4 patent families are classified under C04B (Ceramics, Cement and Refractories). No filings are recorded under adjacent classes covering biological agents, encapsulation systems, or structural monitoring in this corpus.
The filing trend shows zero recorded activity from 2017 through 2023. The first families appear in 2024 and 2025, with two families in 2026. Given publication lag, actual filed volume in 2024–2026 may be higher than currently indexed.
The flat visible assignee structure, absence of a portfolio leader, and unoccupied adjacent IPC branches mean entry barriers from existing IP are currently low. However, the very small corpus size means the technology is pre-commercial and lacks an established licensing ecosystem. follow-up research decisions should weigh the low IP barrier against the early-stage commercialization risk.

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.
