EDLC Electrode/Electrolyte Recovery Patent Snapshot
The EDLC electrode and electrolyte recovery patent space is extremely small and heavily concentrated, with a single applicant — Atlas Power Technologies Inc — holding the dominant position. Annual filing volume peaked in 2020 and has since eased, signalling a field in decline with limited new entrant activity.
Atlas Power Technologies Inc commands the field with minimal competition
Atlas Power Technologies Inc ranks first with 7 patent families, far ahead of every other filer, each of which holds a single patent family. The top five filers collectively account for all activity among the ranked applicants visible in this query, confirming an exceptionally concentrated visible assignee structure.
There is a sharp tier gap: Atlas Power Technologies Inc alone represents the vast majority of the corpus, while the four remaining applicants — Atlas Power Generation Inc, Easwari Engineering College, Chongqing Zhongke Chaorong Technology Co. Ltd., and SRM Institute of Science and Technology (Ramapuram Campus) — each contribute one patent family. No second-tier cluster exists.
| # | Applicant | Patent families | Share |
|---|---|---|---|
| 1 | Atlas Power Technologies Inc | 7 | |
| 2 | Atlas Power Generation Inc | 1 | |
| 3 | Easwari Engineering College | 1 | |
| 4 | Chongqing Zhongke Chaorong Technology Co. Ltd. | 1 | |
| 5 | SRM INST OF SCI & TECH (RAMAPURAM CAMPUS) | 1 |
Atlas Power Technologies Inc’s dominance implies it controls the foundational intellectual property in this niche. Any entrant would need to design around Atlas’s portfolio or seek licensing, while academic and research institutions (Easwari Engineering College, SRM Institute) represent exploratory rather than commercial positions.
The most recent filing periods should be treated with caution: publication lag means activity from the last 18–24 months is likely under-represented in the current count. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
A 2020 filing spike has not been sustained; inorganic chemistry and capacitor classes dominate
The filing trend reveals a sharp, isolated peak in 2020 followed by near-total inactivity, while the technology composition chart shows the field is anchored in two IPC classes with negligible coverage of adjacent disposal and polymer processing branches.
Annual filing trend
Seven of the ten patent families were filed in 2020, creating a pronounced single-year spike. Subsequent years show minimal activity, and the most recent periods (2024–2026) remain subject to publication lag, so apparent zeros should not be read as confirmed inactivity. The overall recent-window growth is negative relative to the 2020 peak.

Non-metallic elements and inorganic compounds (C01B) and capacitors (H01G) together cover nearly all filings, reflecting the visible focus on carbon-based electrode materials and EDLC device structures. Solid waste disposal (B09B), polymer processing (C08J), and destructive distillation/coke (C10B) each appear only once, marking the outer edges of the current patent footprint.

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.
Atlas Power Technologies Inc
Atlas Power Technologies Inc holds 7 patent families — all concentrated in non-metallic elements and inorganic compounds (C01B) and capacitors (H01G), indicating a focus on carbon electrode materials and EDLC device architecture. Momentum data classifies them as a new entrant with 1 recent-period family, suggesting the bulk of their position was built in the 2020 filing spike rather than through sustained recent activity.
families: 7Chongqing Zhongke Chaorong Technology Co. Ltd.
Chongqing Zhongke Chaorong Technology Co. Ltd. holds 1 patent family with coverage in non-metallic elements and inorganic compounds (C01B) and capacitors (H01G), mirroring the visible technology axes. Momentum data also classifies them as a new entrant with 1 recent-period family, indicating their entry is very recent and coming from a small base.
families: 1Frequently asked questions
The corpus contains 10 patent families in scope. This is a very small field relative to broader energy storage or supercapacitor technology areas.
Atlas Power Technologies Inc is the leading filer with 7 patent families, concentrated in non-metallic elements and inorganic compounds and capacitor-related IPC classes. No other applicant holds more than one patent family.
Filing activity peaked in 2020, when 7 patent families were recorded. Subsequent years show near-zero activity. The lifecycle evidence classifies the field as in decline, with a recent-window growth rate of -71% from the peak. The most recent periods remain subject to publication lag.
Australia and Canada each account for two patent records, followed by Europe (EPO) and India with two records each, and China and WIPO with one record each. Australia is the lead filing office, consistent with the visible applicant’s apparent operational base.
No co-applicant pairs are detected in the collaboration data. All filers appear to operate independently, with no consortium or industry-academic joint filing activity recorded in this corpus.
Solid waste disposal (B09B), polymer processing and solutions (C08J), and coke and destructive distillation (C10B) each appear in only one patent record, compared to ten for non-metallic elements and inorganic compounds (C01B) and nine for capacitors (H01G). These three branches represent the sparse outer edges of current coverage.

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.
