Pseudocapacitor Electrode Design Optimization Patent Snapshot
The patent corpus for pseudocapacitor electrode design optimization is extremely small — 4 patent families in scope — with Cellmo Materials Innovation Inc holding the dominant position. Activity peaked in 2020 and has eased since, signalling a field that is early-stage and lightly contested rather than actively growing.
A two-applicant field with near-total concentration
The patent evidence snapshot for pseudocapacitor electrode design optimization is dominated by Cellmo Materials Innovation Inc, which holds 3 of the 4 patent families in scope, placing it first in the applicant ranking. King Fahd University of Petroleum and Minerals accounts for the remaining family, making this a two-applicant field.
The top five filers collectively account for 100% of the combined total of the ranked applicants visible in this query — in practice here, two applicants — indicating extreme concentration with no meaningful second tier.

| 1 | Cellmo Materials Innovation Inc | 3 | |
| 2 | King Fahd University of Petroleum and Minerals | 1 |
Cellmo Materials Innovation Inc’s visible position implies that any organization entering this area will need to design around its existing H01G 11 filings or seek licensing; King Fahd University of Petroleum and Minerals represents the sole academic presence, suggesting limited institutional diversification to date.
The two most recent data points (2025–2026) are subject to publication lag and likely undercount actual filing activity in that window. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
A 2020 peak, minimal subsequent activity, and a single dominant IPC class
The filing trend reveals a brief pulse of activity around 2020 followed by near-silence, while the technology composition is entirely concentrated in H01G (Capacitors), leaving no observed diversification into adjacent classes.
Annual filing trend
The trend shows isolated filings in 2020 (the peak year) and isolated records in 2025 and 2026; all other years in the window show zero filings. The 2025–2026 data points are subject to publication lag and should be treated as minimum counts rather than final figures.

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.
Cellmo Materials Innovation Inc
Cellmo Materials Innovation Inc holds 3 patent families — all classified under H01G 11 (Capacitors) — making it the clear IP leader in this space. Applicant momentum data is not available in the evidence, so trajectory cannot be quantified; however, its position as the visible filer in a near-empty corpus is structurally significant for any new entrant.
families: 3King Fahd University of Petroleum and Minerals
King Fahd University of Petroleum and Minerals holds 1 patent family, also in H01G 11. As the sole academic filer, it represents a potential collaboration or licensing partner for industry players seeking to build on independently developed research. Momentum data is not available in the evidence.
families: 1Frequently asked questions
The evidence shows 4 patent families in scope for this topic, all filed with the United States patent office.
Cellmo Materials Innovation Inc is the leading applicant with 3 patent families, followed by King Fahd University of Petroleum and Minerals with 1 family.
The field is classified as Decline, with annual filings easing back from a peak in 2020. The corpus remains very small across the entire observation window.
All 4 patent records in the evidence are filed in the United States. No other jurisdictions appear in the current corpus.
No co-applicant filings are recorded in the evidence. The two applicants — Cellmo Materials Innovation Inc and King Fahd University of Petroleum and Minerals — appear to have filed independently.
All 4 families are classified under H01G (Capacitors). Adjacent classes such as H01M (electrochemical cells) and inorganic/ceramic materials classes (C01, C04) are absent from the current corpus.

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.
