Resilient Infrastructure Patents: Who Leads, Where the Gaps Are 2026
- Construction materials dominate the claim base. C04B (ceramics, cement & refractories) covers 57.8% of the 45 records in scope, far ahead of any sensing or software class.
- No single assignee has pulled away. The leader holds only 2 records, and the top 5 combined account for 22.2% of all 45 records — a long tail, not a concentrated field.
- Filing is recent and still rising into the data cut-off. Volume was zero in 2017 and reached a peak of 18 in 2025, with India as the dominant receiving office at 38 of the filings tracked.
Top-5 share is the combined record count of the five largest assignees divided by all 45 records in scope (CR5), not by the ranked leaders only.
What the resilient infrastructure patent record actually shows
The search set covers 45 published records filed against claim language for structural load, construction material, deformation sensing, foundation condition, utility networks and occupancy sensing, framed around resilient infrastructure. This is a young, small and geographically concentrated field: filings begin appearing meaningfully only in recent years and the receiving-office mix is dominated by India, with the United States and WIPO PCT filings a distant second and third.
Reading this landscape by patent family rather than raw document count matters here because the field is still building its base — a handful of continuation filings or multi-jurisdiction duplicates could otherwise distort a set this size. Publication lag also means the most recent year, 2026, understates true filing activity; treat the 2025 peak as the most reliable recent signal.
Filing trend and technology composition
Two views of the same 45-record set: how filing volume has moved year over year, and which IPC subclasses the claims actually sit in.
Filing trend, 2017–2026
Volume moved from 0 in 2017 to a peak of 18 in 2025, with 10 recorded by the 2026 partial year. A single climbing curve with no earlier plateau is consistent with a field that only recently attracted patent attention.
IPC subclass composition
C04B (ceramics, cement & refractories) accounts for 57.8% of the 45 records, well ahead of G06Q, E04C and G06N at 11-13% each, and B29B, C08K, E04B and G01N each near 9%. Because records can carry multiple classes, these shares sum to well over 100% and should be read as claim-space overlap, not a partition of the field.
Shares are the percentage of the 45 records in scope. A patent can carry several IPC classes, so the shares add up to more than 100%.

Three patterns stand out once the ranking, IPC composition and receiving-office data are read together.
No dominant incumbent to design around
The leading assignee holds only 2 records and the top 5 combined reach 22.2% of the 45 records in scope. A field this diffuse rewards a well-drafted claim more than it rewards clearing a single blocking patent — there is no single portfolio to freedom-to-operate around.
Material claims, not sensing claims, occupy the space
C04B (ceramics, cement & refractories) covers more than half of all records, while occupancy sensing, deformation sensing and utility-network claims implied by the search terms appear thinly across G01N, E04B and E04C. The dense prior art is in materials; the sensing and network layers remain comparatively open.
Filing activity is not yet globally distributed
India accounts for the large majority of receiving offices in this set, with the United States and WIPO PCT trailing well behind. Applicants targeting US or global protection in this space currently face a thinner prior-art base outside India.
Eureka can read the same corpus for gaps instead of for coverage: under-claimed branches adjacent to resilient infrastructure patent landscape, with the prior art for and against each one.

Ten co-assignee pairs appear in the set, the strongest built around a small cluster of individual co-inventors rather than corporate joint ventures — a sign that much of this field is still academic or early-stage rather than industrially partnered.
Who is filing, and where the gaps sit
The assignee ranking spans 100 companies and research institutions, counted by record, with the leader holding just 2 filings — this is a fragmented field led by academic and individual filers rather than a concentrated industry.
Academic and institutional filers lead
The top of the ranking is occupied by technical institutes and university-affiliated bodies rather than established construction or infrastructure firms, with the fifth-ranked assignee also at 2 records and the tenth at 1. This points to a field still in early research-to-filing translation.
Most of the field files once
Even the top 10 combined reach only 35.6% of the 45 records in scope, meaning the majority of assignees appear with a single filing. That is typical of an emerging area and leaves substantial room for a new entrant to establish a foothold with a well-targeted filing.
Momentum is thin and uneven
Most named assignees in the recent-momentum data show zero filings in the latest year, including several with a -100% year-on-year drop; only one shows continued activity. Momentum here should be read cautiously given publication lag understates the newest year.

Where to take this analysis
The dataset points to open claim space in sensing and network layers, and a filing base still forming outside India. Two directions follow from that.
Draft against the material-heavy prior art
Any new filing touching construction material or cement-based resilience claims enters a space where C04B already covers 57.8% of records — check that claim scope before drafting around structural load or foundation material limitations.
Explore prior art in EurekaWatch the sensing and network layers
Deformation sensing, occupancy sensing and utility-network claims remain thin relative to the materials base, which is where a first-mover claim is more likely to stand without dense blocking art.

No single company or institution dominates this field. The leading assignee in the 45-record set holds only 2 filings, and the top 5 assignees combined account for 22.2% of all records. The leaders that do appear are mostly academic and technical institutes rather than established construction or infrastructure firms, which suggests the field is still moving from research into commercial filing.
The largest single technology area by far is C04B, covering ceramics, cement and refractories, which accounts for 57.8% of the 45 records in scope. Structural building components (E04C), AI-based computing (G06N) and business data processing (G06Q) each cover roughly 11% of records, with building structures, material testing, plastics preparation and polymer additives each near 9%. Because records can carry multiple IPC classes, these figures overlap rather than sum to 100%.
Filing volume rose from zero in 2017 to a peak of 18 records in 2025, indicating growing but recent attention to the field. The 2026 count of 10 is a partial year and, due to the roughly 18-month lag between filing and publication, understates actual filing activity for that period. There are not yet enough complete years of data to state a reliable growth rate.
The evidence points to construction material claims being heavily occupied, with C04B alone covering more than half of all records, while sensing and network-layer claims implied by the search terms, such as deformation sensing, foundation condition monitoring and utility network interdependency, appear far less frequently. A first filing targeting real-time sensor networks or AI-assisted load forecasting for existing structures would face a thinner prior-art base than one targeting cement or ceramic material composition.
India is by far the dominant receiving office in this dataset, with 38 of 45 filings, compared with 5 in the United States and 2 via the WIPO PCT route. This concentration suggests the field's patent activity is currently anchored in Indian academic and institutional filing, with limited parallel protection sought in the US or through international PCT applications so far.
US11722379B2, assigned to the Arizona Board of Regents on behalf of Arizona State University, covers an infrastructure modeling system that simulates the vulnerability of critical interdependent infrastructures. It is one of the more cited records in this set, alongside the related publication US20200287798A1, making it a useful reference point for anyone drafting claims around infrastructure simulation or interdependency modelling. Reviewing its specific claim language is advisable before filing in adjacent simulation-based resilience software.
