Hybrid & Asymmetric Supercapacitor Patent Snapshot
Academic and research institutions — led by King Fahd University of Petroleum and Minerals — dominate a concentrated but still-expanding patent field, with the United States as the dominant filing jurisdiction. Multi-year activity is up on a growth trajectory, though annual volume has eased from its 2021 peak and recent years are further understated by publication lag.
A Concentrated, Institution-Led Field with a Clear Saudi–Indian Core
King Fahd University of Petroleum and Minerals holds the top position among filers, followed by King Abdullah University of Science and Technology and Pondicherry University — all academic or government-research entities, with no large commercial incumbent at the top of the ranking.
The top five filers account for 68% of the combined total across the ranked applicants visible in this query, indicating a markedly concentrated visible assignee structure with a steep drop-off to the tail of the ranking. The tier gap between the top two institutions and the remaining players is significant.

The dominance of Saudi Arabian and Indian research universities suggests that foundational materials and device innovation is being driven by publicly funded R&D rather than by industrial players, which leaves the commercialization pathway comparatively open for corporate entrants.
Patent counts for the most recent 18–24 months are understated due to publication lag and should not be read as a slowdown; the multi-year growth trend remains positive. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
Growth-Stage Field with Capacitor-Core Technology and Emerging Adjacent Branches
The annual filing trend and technology composition together reveal a field in the Growth life-cycle stage, anchored in capacitor device engineering but showing early diversification into battery-adjacent, nanomaterial, and heterocyclic-chemistry branches.
Annual filing trend
Filing activity rose from the 2017 baseline, peaked in 2021, and has continued at a comparable level through 2023–2025; the 2025–2026 figures are understated by publication lag and should not be read as a decline. The 33% recent-window growth confirms the field is expanding on a multi-year basis despite the easing from the 2021 peak.

H01G (Capacitors) is the overwhelmingly visible IPC class, reflecting the core device focus of the corpus. H01M (Batteries, cells and fuel cells) is the next most represented branch, consistent with the hybrid architecture that bridges supercapacitor and battery functionality. Smaller branches — A61B (Diagnosis and surgery), C07D (Heterocyclic compounds), and B82Y (Nanotechnology applications) — signal early-stage diversification toward biomedical sensing, organic electrode materials, and nanomaterial integration.

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.
King Fahd University of Petroleum and Minerals
The top-ranked filer with 4 patent records, concentrated in H01G 11 (Capacitors) and A61B 5 (Diagnosis and surgery) — an unusual combination suggesting research into supercapacitor-powered or supercapacitor-integrated biomedical sensing. Filing momentum is classified as a new entrant in the recent window, indicating that its current position was built quickly rather than accumulated over many years.
patent records: 4Pondicherry University
Tied at 2 patent records and also classified as a new entrant by recent filing trend, Pondicherry University focuses on H01G 11 (Capacitors) alongside B82Y 30 and B82Y 40 (Nanotechnology applications), signaling a nanomaterial-electrode research direction. As a government-funded Indian institution, its IP is likely accessible for licensing discussions, making it a potential collaboration target for industrial players seeking nanomaterial expertise.
patent records: 2Frequently asked questions
The evidence covers 13 patent families in scope. This is a relatively small corpus, reflecting either a narrow query definition or an early-stage / specialized technology niche; findings should be read in that context.
King Fahd University of Petroleum and Minerals is the top-ranked filer with 4 patent records, followed by King Abdullah University of Science and Technology with 3, and Pondicherry University and two other institutions tied at 2 each.
The field is in a Growth life-cycle stage. The recent three-year filing window is 33% above the prior three-year window, confirming multi-year expansion. Annual volume eased from its 2021 peak, and the most recent years (2024–2026) are further understated by publication lag, so apparent flatness in those years should not be read as a real decline.
The United States leads with 10 patent records, followed by India with 5 and one WIPO PCT filing. Coverage in other major energy-storage markets — including China, Japan, South Korea, and Europe — is not evidenced in this corpus, which may indicate freedom-to-operate space or parallel unprotected development in those regions.
The two most-cited documents in the corpus — each with 13 citations — relate to conductive two-dimensional covalent organic frameworks, pointing to organic porous-material electrode innovation as the most technically influential thread. A third highly cited work (11 citations) also concerns 2D covalent organic frameworks, and a fourth covers flexible asymmetric electrochemical cells using nanomaterials.
The sparsest adjacent branches relative to the visible H01G capacitor core are B82Y (Nanotechnology applications, 1 record, 3% share) and C07D (Heterocyclic compounds, 2 records, 6% share). Both have clear technical relevance to next-generation electrode materials — nanostructured carbons and conductive organic frameworks respectively — and low existing IP density. C01G (metal compounds for pseudocapacitive oxides) and C07F (organo-metallic precursors for MOF-derived electrodes) are also under-served at 1 record each.

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.
