Conductive Polymer Supercapacitor Patents: Leaders, Trends & Gaps 2026
A data-backed look at conductive polymer supercapacitor patents: filing trends since 2017, assignee concentration, IPC composition, and where white space remains for new filers.
Filing growth = 2021 (2 records) → 2024 (0); 2024 is the last year we treat as complete. Top-5 share = the 5 largest assignees ÷ all 33 records in scope (CR5), not the ranked leaders only.
What the conductive polymer supercapacitor patent record shows
Conductive polymer supercapacitors sit at the junction of two IPC families: H01G for the capacitor structure and, for a minority of filings, H01M for the battery-adjacent electrochemistry. The scope here is narrow by design — 33 records — which makes this a niche rather than a mainstream capacitor category, and it means individual filings carry more weight in the ranking than they would in a larger field.
Filing activity is concentrated in United States receiving offices, with a much smaller number of records routed through China, the EPO, WIPO, Germany and the UK. That skew suggests the competitive centre of gravity for this specific claim language is a US-prosecuted one, even though conductive polymer electrode chemistry itself is studied globally.

Filing trend and technology composition
The two charts below use the same 33-record denominator throughout, so every share quoted here can be read directly against it.
Filing trend: a niche that has not scaled
Filings rose to a peak of 4 in 2019, then eased back. The evidence-backed comparison point is 2021 (2 records) against 2024 (0 records), a -100% move over that three-year span. Because publication lags filing by roughly 18 months, 2025 and 2026 counts are not yet complete and should not be read as confirming a further decline.
Publication lags filing by roughly 18 months, so 2025 onwards are still filling in. Growth rates on this page therefore end at 2024; running them to the last bar would understate the field.
IPC composition: capacitor-first, polymer-adjacent
H01G covers all 33 records by construction of the search. Beyond that, H01M appears in 27.3% of the 33 records, and smaller polymer-chemistry classes — B82Y, C08G, C08K, C08F, C08L, C09D — each cover a handful of records, at 9.1% or 6.1% of the 33. Because a record can carry several classes, these shares add up to more than 100%.
Shares are the percentage of the 33 records in scope. A patent can carry several IPC classes, so the shares add up to more than 100%.

Gel polymer electrolyte supercapacitor (US20240021876A1)
Filed by Imam Abdulrahman Bin Faisal University, this January 2024 filing claims a gel polymer electrolyte built from molybdate(VI) salts dispersed in an acrylamide-based hydrogel matrix, paired with a supercapacitor structure that places electrodes on either side of that electrolyte. The filing is evaluated against specific capacitance, energy density, power density, resistance and cycling stability.Dates, assignee and publication number are rendered from the underlying record.

Citation counts reward older filings that have had more time to accumulate citations inside the searched corpus; treat this table as a map of technical influence, not of current commercial leadership.
Patent titles are shown in the language they were filed in, not translated, so that each record stays verifiable against the original filing — a translated title will not match in Eureka or in any national register. Each row carries its publication number; clicking a row searches Eureka by that number.

Three figures from the ranking and citation tables set the practical boundaries for anyone deciding where to file next.
The top of the field is narrow
Five assignees hold 16 of the 33 records in scope, 48.5% of the total. The ranked list runs to 25 companies, so most of that list holds one or two records each — a long tail sitting under a small dense cluster at the top.
Concentration deepens only slightly past five
Extending from the top 5 to the top 10 assignees adds another 24.2 points of share, bringing the cumulative total to 72.7% of the 33 records. The remaining 15 ranked assignees and any unranked filers divide the last quarter of the field.
Citation weight sits on older continuous-process claims
The two most-cited records both describe a continuous process for producing supercapacitor electrodes with high energy densities, one a granted patent and one its earlier application. Citation counts favour records that have simply been in the corpus longer, so this is a signal of technical influence rather than of what is newest.
Most filings stay inside pure capacitor claims
Only 27.3% of the 33 records also carry an H01M battery-and-cell classification, meaning the bulk of this field is claimed as capacitor technology rather than as a battery-supercapacitor hybrid, even though conductive polymer chemistry is shared across both.
Eureka can read the same corpus for gaps instead of for coverage: under-claimed branches adjacent to conductive polymer supercapacitor patent landscape, with the prior art for and against each one.
Where to take this next
The dataset points to specific next steps rather than a single conclusion.
Map the claim language of the top 5
Before filing, pull the granted claims of the five assignees holding 48.5% of the 33 records to see exactly which electrode structures and electrolyte formulations are already occupied.

Publication lag means the apparent drop to 2024 is not final. Re-check the trend once 2025 filings finish publishing before drawing conclusions about slowdown.
Track filing trends in EurekaTest white space in the polymer-chemistry classes
C08G, C08K, C08F, C08L and C09D each cover only 2-3 of the 33 records. These are the classes worth a closer novelty search before committing claim language.
Run a white space search in EurekaQuestions practitioners ask about this field
The assignee ranking for this dataset lists 25 companies across 33 total records in scope. That is not a top-50 or top-100 cut — it is the full ranked list the data returns. Five of those companies together hold 48.5% of all 33 records, so the field has a dense cluster at the top and a long tail of single- or double-filing entrants below it.
Filings peaked at 4 records in 2019 and the comparison point of 2021 (2 records) against 2024 (0 records) shows a -100% move over that three-year span. However, publication typically lags filing by around 18 months, so 2025 and 2026 figures are still incomplete and should not be read as proof the field has stopped moving — only that 2024 was, on the evidence available, quiet.
Every one of the 33 records in scope carries an H01G capacitor classification by construction of the search. Beyond that, 27.3% also carry H01M, the batteries-and-fuel-cells class, showing a partial but real overlap with battery electrochemistry. Smaller polymer-chemistry classes — covering additive polymers, condensation polymers, coatings and nanotechnology applications — each appear in only 2-3 of the 33 records, at 6.1% to 9.1% shares.
The most-cited record is US10083801B2, a granted patent on a continuous process for producing supercapacitor electrodes with high energy densities, cited 24 times, with its earlier application US20180174766A1 cited 19 times on the same subject matter. A separate record, US20170316891A1, covers a supercapacitor with high volumetric energy density and is cited 13 times. These citation counts reflect how long a record has sat in the corpus as much as its technical importance, so they should be read as a map of influence rather than a ranking of current relevance.
The polymer-chemistry side of the field is thinner than the capacitor-structure side: classes covering addition polymers, polymer compositions and coatings each touch only 2 of the 33 records, at 6.1% shares. Combined with a ranked assignee list of 25 companies where most hold only one or two records, this points to formulation-level claims — specific electrolyte or coating chemistries — as less crowded than electrode-structure claims, which sit under the most-cited and most heavily filed records.

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.
