GFRP Weathering & Moisture Durability Patent Snapshot
The GFRP weathering and moisture durability patent space is in a Growth stage, with filing activity expanding on a multi-year basis and a fragmented field where no single player holds a commanding share. Jager Invest leads the applicant ranking, but the top five filers together account for only 27% of the hundred largest filers’ combined total, signaling open competitive space.
Fragmented field with a slim leader and room for new entrants
Jager Invest Kereskedelmi Szolgaltato es Ingatlanhasznosito Kft leads the applicant ranking with 7 patent records, followed by Avery Dennison Corporation (5), Materia Inc (4), Mitsui Chemicals Inc (4), and International Business Machines Corporation (4). No single organization approaches dominance.
The top five filers account for 27% of the ranked applicants visible in this query’ combined total — a low concentration figure that is typical of an emerging, cross-industry field where chemists, composites specialists, and electronics manufacturers each hold partial positions.

The slim lead of the top applicant suggests that a targeted filing program in focused sub-areas could meaningfully shift rankings, and that no incumbent has yet established the kind of portfolio depth that deters entry.
Filing counts for the most recent 18–24 months are understated due to publication lag; the apparent moderation in 2023–2024 data should not be interpreted as a slowdown. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
Multi-year growth with polymer processing at the technical core
Two charts frame the field’s trajectory: the annual filing trend reveals where activity is concentrated in time, while the IPC branch breakdown exposes the visible technical routes and the branches that remain comparatively sparse.
Annual filing trend
Activity was negligible before 2018, picked up from 2018 onward, and the three-year recent window shows a 200% growth rate versus the prior comparable period. The apparent dip in 2026 and moderation in 2023 reflect publication lag, not a real decline — treat those bars as understated.
↗ Hover for values · click a bar to ask EurekaTechnology composition
C08J (Polymer processing and solutions) is the visible branch, reflecting the field’s focus on matrix-fiber interface chemistry. C08L (Polymer compositions), B29C (Shaping of plastics), and C08K (Use of additives in polymers) form a secondary cluster, together covering compounding and processing routes. Adjacent branches such as C03C (Glass and enamel compositions), B32B (Layered products), and H05K (Printed circuits) appear at lower counts, pointing to application-specific uses in electronics and structural laminates.

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.
Jager Invest Kereskedelmi Szolgaltato es Ingatlanhasznosito Kft
Leads the field with 7 patent records, focused exclusively on C08J (Polymer processing and solutions) across matrix impregnation and composite laminate chemistry sub-classes. The portfolio’s depth in a single IPC class suggests a deliberate claim strategy around fiber-matrix interface treatments. Momentum data are not available for this applicant in the evidence set.
patent records: 7The Boeing Company
Boeing entered the field as a new entrant in the recent period (3 recent patent records, trend: new entrant), with technical focus on B29C 70 (Shaping of plastics — composite forming) and B64C 1 (Aeroplanes and helicopters), reflecting aerospace-grade structural GFRP durability as its primary application context. Its entry signals that prime aerospace OEMs are beginning to build formal IP positions in this space.
patent records: 3Frequently asked questions
The evidence set covers 20 patent families in scope for this topic.
Jager Invest Kereskedelmi Szolgaltato es Ingatlanhasznosito Kft leads with 7 patent records, followed by Avery Dennison Corporation (5), and Materia Inc, Mitsui Chemicals Inc, and International Business Machines Corporation each with 4 patent records.
The United States leads with 23 patent records, followed by China (13), Europe via EPO (8), Japan (7), and India (6). PCT filings account for 4 records, indicating some applicants are seeking multi-region protection.
The field is classified as Growth. Annual filings are still rising and the recent three-year window recorded 200% growth versus the prior comparable period. Publication lag means the most recent data points understate actual activity.
C08J (Polymer processing and solutions) is the visible branch, reflecting the centrality of matrix-fiber interface chemistry. C08L (Polymer compositions), B29C (Shaping of plastics), and C08K (Use of additives in polymers) form the secondary cluster.
Yes. The evidence identifies one active co-applicant pair: Zhejiang University and Jiangsu Liside New Material Co., Ltd., who jointly filed 2 patent records. Broader collaborative activity is limited based on current evidence.

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.
