Hybrid Supercapacitor Manufacturing Patent Snapshot 2026
The hybrid supercapacitor manufacturing patent space is in a growth phase, with a strong concentration of activity in South Korea and an academic-institution-dominated applicant pool. Korea Institute of Ceramic Engineering and Technology leads by patent records, and recent-window growth of 167% signals that the field is still expanding on a multi-year basis, though annual volume has eased from its 2023 peak.
South Korean research institutes dominate a nascent, concentrated field
Korea Institute of Ceramic Engineering and Technology holds the top position with 6 patent records, followed by King Fahd University of Petroleum and Minerals with 4 and University of Sharjah and Yeungnam University Industry Cooperation Foundation each with 3. The applicant pool is composed almost entirely of academic and public research institutions, with Samsung Electro-Mechanics Co., Ltd. being the most prominent industrial filer.
The top five filers account for 41% of the combined total across the ranked applicants visible in this query, indicating moderate-to-high concentration at the apex for a field of this size. The gap between the leader and the second tier is meaningful but not insurmountable, and several new entrants have entered the ranking in recent periods.

The dominance of Korean institutions, combined with South Korea accounting for the largest share of jurisdictional filings, suggests that Korean government-backed research priorities are a primary driver of the current IP agenda. Industrial participants remain sparse, which may indicate that commercial translation is still in early stages.
Filing counts for the most recent 18–24 months are likely understated due to standard patent publication lag; the apparent moderation in 2024–2026 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.
167% recent-window growth with a capacitor-dominant technology mix
Two charts together reveal the pace and composition of activity: the annual filing trend shows where the field stands in its growth cycle, and the IPC composition chart shows which technical branches capture the bulk of patent activity.
Annual filing trend
Filings were negligible through 2018–2019, accelerated from 2020 onward, and reached a visible peak in 2023 with 8 patent records. The three-year recent window sits 167% above the prior comparable window, confirming multi-year expansion. Data for 2024–2026 are likely understated by publication lag and should not be read as a trough.

H01G (Capacitors) accounts for the large majority of IPC-coded records, reflecting core electrode, electrolyte, and cell-assembly work. Secondary branches — C01B (non-metallic elements and inorganic compounds), H01M (batteries, cells and fuel cells), A61B (diagnosis and surgery), and H01L (semiconductor devices) — each represent a small fraction, pointing to material synthesis and cross-domain application threads that remain comparatively sparse.

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.
Korea Institute of Ceramic Engineering and Technology
The top filer with 6 patent records, concentrated across H01G 11 (electrochemical double-layer capacitors), H01G 9 (electrolytic capacitors), and H01G 13 (capacitor manufacturing). Its co-filing relationship with Vinatech Co., Ltd. is the only confirmed collaboration in the dataset, suggesting a deliberate bridge toward commercial manufacturing. No momentum trend is recorded, indicating an established rather than newly accelerating position.
families: 6King Fahd University of Petroleum and Minerals
The second-ranked filer with 4 patent records and a momentum trend of new entrant, meaning its recent filings represent a first appearance in this specific space. Its technology focus spans H01G 11 (electrochemical capacitors) and A61B 5 (biomedical diagnostics), suggesting an interest in energy harvesting or biomedical power-supply applications of hybrid supercapacitors — a relatively differentiated angle compared to the leader.
families: 4Frequently asked questions
There are 30 patent families in scope for this analysis. The corpus spans global filings and is drawn from PatSnap Eureka using a targeted search on hybrid supercapacitor manufacturing.
Korea Institute of Ceramic Engineering and Technology leads with 6 patent records, followed by King Fahd University of Petroleum and Minerals with 4, and University of Sharjah and Yeungnam University Industry Cooperation Foundation each with 3.
The field is classified in a Growth stage. The recent three-year filing window is 167% above the prior comparable window, confirming multi-year expansion. Annual volume peaked in 2023 and has eased since, but the most recent data years are understated by standard publication lag, so that easing should not be interpreted as a genuine decline.
South Korea accounts for the largest share of jurisdictional filings, followed by the United States, India, China, and WIPO PCT. The South Korean dominance reflects the concentration of leading institutional filers based there.
Evidence shows one confirmed co-applicant relationship: Korea Institute of Ceramic Engineering and Technology and Vinatech Co., Ltd. have filed jointly. The rest of the applicant pool files independently, indicating that formal cross-institutional collaboration remains limited in this space.
The most-cited patent in the dataset — titled ‘High energy density and high power density asymmetric supercapacitor based on eggshell inner membrane’ — has received 22 citations. The second most cited covers negative electrode design for asymmetric supercapacitors with 11 citations, and an all-solid-state asymmetric supercapacitor patent ranks third with 10 citations. These citation leaders concentrate on asymmetric electrode architectures and solid-state electrolyte configurations.

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.
