Micro-Pseudocapacitor Patent Snapshot 2026
Dedicated micro-pseudocapacitor patent activity is at an embryonic stage, with a single patent family in scope filed in India by Nanotech Energy and the Regents of the University of California. The field is effectively an open research frontier with no established filing competition to speak of.
A nascent field with a single identifiable filing
The corpus contains one patent family, jointly attributed to Nanotech Energy Inc and the Regents of the University of California, making the two applicants co-equal leaders at this point in time.
Concentration is absolute: the top five filers account for all filings among the ranked applicants visible in this query, a figure that reflects the extreme sparsity of the space rather than deliberate consolidation by incumbents.
| # | Applicant | Patent records | Share |
|---|---|---|---|
| 1 | Nanotech Energy Inc | 1 | |
| 2 | Regents of the University of California | 1 |
The current leader positions imply little more than first-mover status; there is no evidence of a portfolio war or defensive blocking strategy in this specific sub-field.
The corpus covers approximately the last ten years of global filing activity; very recent filings may not yet have been published and are therefore under-counted. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
A single filing in 2018 with no subsequent activity on record
The annual trend and the technology-branch breakdown together define a field that has not yet attracted sustained patent investment. Both views underscore the opportunity for early entrants.
Annual filing trend
One filing was recorded in 2018; no further filings appear in any subsequent year through 2026. Because the most recent 18–24 months are subject to publication lag, the absence of post-2018 records should be read as a very sparse, not necessarily zero, pipeline.

The single family spans two IPC branches — H01G (Capacitors) and H01M (Batteries, cells and fuel cells) — reflecting the hybrid energy-storage character of pseudocapacitive devices. Neither branch has attracted additional filings in this specific sub-field.

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.
Nanotech Energy Inc
Nanotech Energy holds one patent record in this sub-field, co-filed with the University of California. No applicant momentum data is available, so trajectory cannot be assessed. Their technology emphasis covers both the H01G capacitor and H01M battery/fuel-cell branches, consistent with a graphene-based hybrid energy-storage focus.
patent records: 1Regents of the University of California
The Regents of the University of California (appearing in the evidence as both RGT UNIV OF CALIFORNIA and the translated form) hold one patent record as co-applicant. Their documented focus mirrors Nanotech Energy’s across H01G and H01M. No momentum data is available to indicate whether further filings are in progress.
patent records: 1Frequently asked questions
The current corpus contains one patent family in scope. This reflects either very early-stage IP activity in this specific sub-field or that much of the relevant work is filed under broader supercapacitor or energy-storage classifications.
Nanotech Energy Inc and the Regents of the University of California are the only two applicants on record, both appearing as co-filers on the single identified family.
India is the only jurisdiction recorded in the evidence. No filings are documented in the US, EP, CN, JP, or KR offices for this specific sub-field.
The corpus spans H01G (Capacitors) and H01M (Batteries, cells and fuel cells), reflecting the hybrid energy-storage nature of pseudocapacitive devices.
One filing was recorded in 2018. No filings appear in any year from 2019 through 2026 in the evidence, though recent years may be under-counted due to publication lag.
The extreme sparsity of the corpus — one family, one jurisdiction, two co-applicants — suggests that the IP landscape is almost entirely open. A new entrant filing in major offices with differentiated electrode or integration technology would encounter minimal prior art in this specific sub-field, though broader supercapacitor and battery prior art would still need to be navigated.

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.
