GFRP In-Situ Cure Monitoring Patent Snapshot 2026
The patent corpus for GFRP in-situ cure monitoring is extremely sparse, with only a single patent family on record and activity concentrated in a single filing year (2024). The field is effectively pre-competitive, presenting wide open space for organizations willing to establish early IP positions.
A field with a single patent family and two named filers
The corpus contains just one patent family in scope, jointly associated with Citius Composites Pte Ltd and Harbin Engineering University as the two applicants of record. The top five filers hold one hundred percent of the ranked applicants visible in this query’ combined total — a reflection of the corpus size rather than aggressive consolidation.
There is no meaningful tier structure to describe. With only one patent record identified, the assignee snapshot is essentially blank, and no concentration metric derived from this corpus should be extrapolated to imply broader market dominance.
| # | Applicant | Patent records | Share |
|---|---|---|---|
| 1 | Citius Composites Pte Ltd | 1 | |
| 2 | Harbin Engineering University | 1 |
The positions of both filers are nascent. Citius Composites Pte Ltd is flagged as a new entrant with a single recent record; Harbin Engineering University similarly holds one record. Neither has established a portfolio that could create freedom-to-operate barriers at scale.
Only one filing year (2024) shows activity; publication lag means any filings from 2024 onward may not yet have surfaced in this corpus, so the true activity level could be modestly higher than the data currently reflect.
A single 2024 filing pulse against a flat baseline
The annual filing trend shows zero activity from 2017 through 2023, a single record appearing in 2024, and no records yet visible in 2025–2026. The technology composition reflects the IPC classes tagged to that one record.
Annual filing trend
The entire trend line is flat at zero until a solitary record appears in 2024. No conclusion about growth trajectory can be drawn from a single data point; the 2024–2026 window should be treated as under-counted due to publication lag.

The single family is tagged across five IPC classes — A23K (animal feed), A23L (foods and non-alcoholic beverages), B29C (shaping of plastics), C08B (polysaccharides and derivatives), and G01N (material analysis and testing). The B29C and G01N classes are most directly relevant to composites processing and cure-state measurement; the food-related classes (A23K, A23L) and C08B likely reflect the breadth of the claims or classification ambiguity in this sparse record.

一种混凝土中GFRP筋的长期性能监测方法
本发明公开了一种混凝土中GFRP筋的长期性能监测方法。是一种用于混凝土构件中GFRP筋的拉伸强度的实时预测、以及混凝土中GFRP筋安全服役期限的预测方法。本方法需要在GFRP筋混凝土构件中的相关位置预埋电极、导线并使其与恒电位仪相连,进而测量并记录相关位置混凝土的电阻值,再进行数据处理,整个过程可以实现对GFRP筋混凝土构件中GFRP筋的耐久性能进行无损的实时监测,同时通过混凝土电阻率与混凝土中GFRP筋的退化对应关系的标定试验的结果进行GFRP筋的性能退化的量化。另本方法也可用于GFRP筋混凝土结构的寿命预测。本发明能够简单有效地监测GFRP筋的性能。 (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. 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.
Citius Composites Pte Ltd
Citius Composites Pte Ltd holds one patent record, classified under B29C 70 (shaping of plastics), A23K 10 (animal feed), and A23L 33 (foods and non-alcoholic beverages). Its momentum is flagged as a new entrant — the filing appeared only in the most recent active year. The breadth of IPC classes suggests either wide-ranging claims or multi-domain classification of a single innovation.
patent records: 1Harbin Engineering University
Harbin Engineering University holds one patent record focused on G01N 27 (material analysis and testing), which maps most directly to in-situ sensing and cure-state measurement. No momentum data beyond the single record is available; the university’s focus on sensing methods could make it a relevant collaborator or prior-art reference for entrants targeting electrochemical or dielectric cure-monitoring approaches.
patent records: 1Frequently asked questions
The retrieved corpus contains one patent family in scope. This reflects either a genuinely nascent state of patenting in this specific area or the influence of the search query scope; either way, the field is extremely sparsely covered as of the available evidence.
Two applicants appear in the corpus: Citius Composites Pte Ltd and Harbin Engineering University, each holding one patent record. Neither has established a portfolio lead; both should be considered early-stage participants rather than entrenched incumbents.
The single patent family has been filed in China and India. No filings have been identified in the United States, European Patent Office, Japan, South Korea, or other major composites-manufacturing jurisdictions.
The corpus record is tagged across five IPC classes: A23K (animal feed), A23L (foods and non-alcoholic beverages), B29C (shaping of plastics), C08B (polysaccharides and derivatives), and G01N (material analysis and testing). B29C and G01N are most directly relevant to composites processing and cure-state measurement.
The trend data show zero filings from 2017 through 2023, a single record in 2024, and no records yet visible in 2025–2026. A lifecycle stage cannot be assigned from a single data point. The 2024–2026 window is subject to publication lag, so the true recent activity level may be modestly higher.
The evidence identifies one highly cited work: a Chinese-language reference on long-term performance monitoring of GFRP bars in concrete, which has accumulated eight citations. The representative patent records in the corpus carry the numbers CN104931541A and IN202421038006A.

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.
