Electric Drivetrain for Airport Ground Support Patent Landscape
The patent corpus for electric drivetrains in airport ground support is extremely small and fully concentrated in a single filer, Aurora Flight Sciences Corp, which holds all 6 families in scope. Filing activity peaked in 2019 and has since ceased, leaving the field in a post-peak decline phase with no new entrants on record.
Aurora Flight Sciences holds the entire recorded landscape
Aurora Flight Sciences Corp is the sole ranked applicant, accounting for all patent families in the corpus. The top five filers’ share of the hundred largest filers stands at 100%, which in practice reflects a one-player field.
There is no meaningful tier gap because there is only one tier. No challengers, fast followers, or university filers appear in the ranking, indicating that formal IP activity in this precise intersection of electric drivetrains and airport ground support has been almost entirely absent outside Aurora.

Aurora’s exclusive position means the landscape carries minimal blocking complexity for a new entrant, but it also signals that commercial development in this space has not yet attracted the broad R&D investment that would normally generate a competitive patent thicket.
The most recent years of the trend data are subject to publication lag, so the absence of post-2019 filings should be treated as indicative rather than definitive until further records publish. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
Burst of activity in 2018–2019, then full cessation
The annual filing trend and technology composition together reveal a narrow, time-limited burst of IP creation followed by a sustained absence of new filings across all IPC branches.
Annual filing trend
Filings first appeared in 2018, peaked at four families in 2019, and have recorded zero activity in every subsequent year through 2026. Because patent publication typically lags filing by 18–24 months, any activity in the most recent window may not yet be visible; however, the multi-year zero run from 2020 onward is unlikely to be explained by lag alone.

H02K (electric motors and generators) is the dominant IPC class, appearing across all families in scope, followed by B64D (aircraft equipment) and B64C (aeroplanes and helicopters). F04D (non-positive-displacement pumps, consistent with motor cooling) appears in two families, aligning with the top-cited patent theme of motor cooling systems. The mix is tightly focused on electromechanical motor design within an aviation platform context.

Motor Cooling System And Method
A thrust assembly motor is described, which can be used in a distributed electric propulsion system. The thrust assembly motor may include a revolved-wedge shaped ring on a leading edge of a motor stator, with a row of axial stator blades extending therefrom. The revolved-wedge shaped ring provides a mounting surface for the axial stator blade row while… (excerpt from the patent abstract)

What the structure means for R&D investment decisions
The combination of a single filer, a post-peak lifecycle, and a narrow IPC footprint creates a clear signal about where IP risk is low and where technical gaps remain unfilled.
Post-peak decline: activity eased after 2019
The lifecycle stage is classified as Decline, with annual filings easing back from the 2019 peak and no recorded activity since. This indicates that the initial wave of formal IP creation around electric motor integration for airport ground-support platforms has run its course without a second cohort of filers entering the space. A new entrant would be building on a sparse prior-art base rather than navigating a crowded field.
Lifecycle: DeclineSingle-filer landscape with no recorded challengers
Aurora Flight Sciences Corp accounts for the entirety of the ranked corpus, and the top five filers’ share of the hundred largest filers is 100%. This level of concentration is unusual and reflects either very early-stage niche development or limited commercial interest to date. Freedom-to-operate risk is correspondingly low for new entrants, though Aurora’s families should be individually reviewed for claim scope before drawing firm conclusions.
Concentration: MonopolarNo co-applicant relationships recorded
Evidence on co-filing partnerships is pending; the collaboration data contains no entries. The absence of co-applicants reinforces the single-entity narrative and suggests that no consortium, university, or supply-chain partner has joined Aurora in formal IP co-ownership in this topic. This is either an early-market signal or an artifact of the small corpus size.
Collaboration: Evidence pendingEurope and the United States are the only active jurisdictions
Patent records appear across Europe (EPO), the United States, Germany, and Austria. The EPO and US filings each account for two records, with the German and Austrian records likely derived from the EP grant. No filings appear in Asia-Pacific or other major manufacturing jurisdictions, leaving those markets open from an IP-protection standpoint.

Frequently asked questions
The corpus contains 6 patent families in scope. This is a very small corpus, indicating that formal IP activity at this specific technology-application intersection is nascent or niche.
Aurora Flight Sciences Corp is the sole ranked applicant and holds all patent families in the corpus. No other filer appears in the ranking.
Filing activity peaked in 2019 with four families recorded that year. No filings have been recorded in any subsequent year through 2026. While publication lag can affect the most recent 18–24 months, the multi-year zero run from 2020 onward goes well beyond typical lag windows.
The lifecycle is classified as Decline, reflecting annual filings easing back from the 2019 peak with no subsequent activity recorded. This does not preclude a future uptick if commercial interest grows, but based on current evidence the field is in a post-peak phase.
Filings have been made in Europe (EPO), the United States, Germany, and Austria. No Asia-Pacific or other major manufacturing jurisdictions appear in the evidence, leaving those markets without recorded IP coverage in this corpus.
The dominant IPC class is H02K (electric motors and generators), present across all families. The most-cited patents in the corpus relate to motor cooling systems and methods. Secondary coverage spans B64D and B64C (aircraft equipment and airframe integration) and F04D (non-positive-displacement pumps, relevant to cooling subsystems).

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.
