EV Fast Charging for Airport Ground Support Patent Landscape
The patent corpus for EV fast charging applied to airport ground support equipment is nascent, comprising a single patent family filed in 2020 and concentrated entirely with one applicant, SIFLY AVIATION INC. The field shows no follow-on annual filings through the available record, signalling an early and highly underpopulated landscape with significant room for new entrants.
SIFLY AVIATION INC holds the sole position in a nascent, one-family corpus
The applicant ranking is maximally concentrated: SIFLY AVIATION INC accounts for the only patent family on record, ranking first by default in a corpus of one.
The top five filers’ share of the ranked applicants visible in this query stands at 100%, which in this case reflects the extreme sparsity of the field rather than coordinated dominance by a cohort of active players.
| # | Applicant | Patent families | Share |
|---|---|---|---|
| 1 | SIFLY AVIATION INC | 1 |
SIFLY AVIATION INC’s solitary position implies that no major aerospace OEM, ground-handling operator, charging-infrastructure provider, or automotive supplier has yet staked patent territory in this specific intersection of electric vehicle charging and airport ground support.
The most recent filing years should be read with caution given standard patent-publication lag; absence of visible filings after 2020 may partly reflect records not yet published rather than confirmed inactivity. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
A single 2020 filing peak and a three-branch technology mix define the landscape
The annual trend and technology composition together reveal a field that sparked briefly in 2020 and has not generated observable follow-on activity, spread across three IPC branches that map cleanly onto the system-level challenge.
Annual filing trend
The sole patent family was filed in 2020; all other years in the window show zero activity. Years after 2023 should be treated as potentially under-counted due to publication lag, so the absence of visible filings in 2024–2026 cannot be interpreted as confirmed inactivity.

The single family spans three IPC branches — B60L (electric vehicle propulsion), B64D (aircraft equipment), and H02J (power supply and grid systems) — reflecting the cross-disciplinary nature of the problem: ground-vehicle charging hardware, airside operational integration, and electrical power delivery are all implicated simultaneously.

Aircraft charging unit
A method of charging a battery system of an electrically powered aircraft that is at a location on the ground. The method moves an Aircraft Charging Unit (ACU) to a position proximate to the location, the ACU having a set of storage batteries, a charge controller, and a connection system. The method further couples the set of storage batteries to the… (excerpt from the patent abstract)

What the landscape structure means for R&D investment decisions
With only one patent family on record, structural reads are necessarily high-level; the landscape is better understood as a blank canvas than a contested arena.
Field is in early decline from a single-event peak
The lifecycle stage is classified as Decline: annual filings eased back from the 2020 peak and have not recovered in the visible record. However, in a corpus of one family, ‘decline’ is effectively synonymous with ‘no follow-on activity yet observed.’ The field has not progressed through a growth phase, and the lifecycle label should be read as a descriptor of filing volume, not of commercial relevance.
Lifecycle: DeclineMaximum concentration in a minimal corpus
SIFLY AVIATION INC holds 100% of the documented patent activity. This is not a sign of competitive entrenchment but of an unpopulated space: no incumbent has built a blocking position, and freedom-to-operate risk from existing patents is limited to this single family. Any new entrant would immediately reshape the concentration picture.
HHI: MaximumNo co-applicant activity on record
Evidence pending: the collaboration dataset contains no recorded co-applicant pairs. This is consistent with the nascent state of the corpus and does not preclude informal research partnerships or future joint filings between ground-handling companies, airport authorities, and charging-infrastructure vendors.
Co-filings: NoneUnited States is the sole jurisdiction on record
All patent activity is filed and granted in the United States. No European, Chinese, or PCT filings appear in the dataset, suggesting that international patent protection in this intersection has not yet been pursued. This leaves substantial geographic white space across all major aviation markets outside the US.

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.
SIFLY AVIATION INC
SIFLY AVIATION INC holds 1 patent family — the entirety of the documented corpus — filed in 2020 and granted in the United States. Applicant momentum data is not available for the period covered, so trajectory direction cannot be confirmed from the evidence. The company’s position as the sole filer gives it first-mover status in a space that remains essentially open.
families: 1HIVESPOT INC
HIVESPOT INC appears in the route matrix with a technology focus spanning B60L 53 (EV charging systems), B60L 58 (battery management), and B64D 27 (aircraft power supply). No ranked family count is available for HIVESPOT INC in the top-100 applicant list, so its documented filing volume is below the threshold or not separately counted in this corpus slice. Its technology emphasis nonetheless signals engagement with the same cross-disciplinary problem set.
families: evidence pendingFrequently asked questions
The current corpus contains 1 patent family in scope. This reflects the nascent state of the field rather than a mature, well-documented technology area.
SIFLY AVIATION INC holds the only documented patent family and is therefore the sole ranked applicant in the top-100 applicant list for this topic.
The single patent family spans three IPC branches: B60L (electric vehicle propulsion), B64D (aircraft equipment), and H02J (power supply and grid systems), reflecting the cross-disciplinary scope of the technology.
The United States is the only jurisdiction represented in the current evidence. No European, PCT, or other national filings appear in the dataset.
The lifecycle is classified as Decline, meaning annual filing volume eased back from its 2020 peak. In a corpus of one family, this effectively means no follow-on filings have been observed in the visible record since 2020.
Yes, by any measure. With only one patent family on record, the vast majority of technically relevant sub-problems — including automated opportunity charging, multi-vehicle fleet demand management, and international patent coverage — remain unaddressed in the documented 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.
