Vehicle-to-Grid System for Electric Aircraft Patent Landscape
Vehicle-to-Grid System for Electric Aircraft Patent Landscape in 2026
The vehicle-to-grid (V2G) system for electric aircraft patent space is highly concentrated, with Beta Air LLC holding an overwhelming share of the 28 families in scope and the United States dominating filing activity. The field is in a growth phase on a multi-year basis, though annual volume has eased from its 2021 peak, leaving meaningful white space in drone charging, battery management, and RF communications adjacent branches.
Beta Air dominates a nascent, highly concentrated field
Beta Air LLC leads all applicants with 23 patent families, followed by Denso Corporation with 5 patent families — together accounting for the entirety of the top ranked applicants in this space.
The top five filers hold 100% of the combined total among the hundred largest filers, signaling extreme concentration in a nascent technology niche. The tier gap between Beta Air and Denso is substantial, reflecting Beta Air’s role as the primary architect of foundational V2G-electric-aircraft IP.
| # | Applicant | Patent families | Share |
|---|---|---|---|
| 1 | Beta Air LLC | 23 | |
| 2 | Denso Corporation | 5 |
Beta Air’s commanding position implies that any new entrant or challenger must either design around its core charging, safety, and bidirectional power transfer claims or pursue differentiated technical routes — such as drone-specific architectures or advanced battery cell integration — where coverage is sparse.
The most recent filing years are further understated by publication lag; the competitive picture may tighten as pending applications publish. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
A 2021 filing surge established the field; technology mix centers on power supply and EV propulsion
Activity in this space effectively began in 2021 with a sharp burst of filings, followed by a moderated but sustained level of activity. The technology composition is anchored by grid and power-supply IP, with meaningful secondary coverage in EV propulsion and ground infrastructure for aircraft.
Annual filing trend
Filings were absent prior to 2021, then surged to a peak that year before settling into a lower but continuing cadence. The 2024 and 2025 data points reflect publication lag and should not be read as a real decline — actual activity in those years is likely understated. The overall three-year recent window remains above the prior three-year baseline, confirming net growth.

What the structure means for R&D investment
The combination of high concentration, a clear technology core, and sparse adjacent branches creates a landscape where strategic positioning depends heavily on route selection and timing.
Growth stage — multi-year expansion with annual volume easing from the 2021 peak
The lifecycle evidence classifies this field as Growth: the recent three-year filing window sits well above the prior three-year baseline, reflecting a 27% growth rate. However, annual volume has eased from its 2021 peak, meaning the field is still expanding structurally but is no longer in its initial burst phase. Entrants still have a realistic window to establish positions before the space matures further.
Growth · Post-Peak AnnualSingle-firm dominance with one emerging challenger
Beta Air LLC accounts for 23 of the ranked patent families; Denso Corporation holds 5. Together they represent 100% of the top-filer cohort, leaving virtually no dispersed mid-tier. This structure means that IP freedom-to-operate analysis must center on Beta Air’s claims, and any new entrant faces significant blocking risk on core charging and safety architectures without a differentiated technical approach.
High ConcentrationNo co-applicant filings detected in this landscape
The collaboration evidence shows no recorded co-applicant filings in this space. This absence suggests that V2G-electric-aircraft IP is currently being developed entirely within individual organizations rather than through consortia or joint ventures. It also signals an opportunity: a consortium filing or standards-body engagement could rapidly shift the competitive dynamic and establish shared baseline IP.
Evidence Pending · No Co-filersUnited States is the dominant jurisdiction; international coverage is thin
Filing activity is heavily concentrated in the United States, followed by Europe (EPO) and WIPO (PCT) with minimal coverage. This narrow jurisdictional footprint means that protection in non-US markets — particularly Asia, where Denso is headquartered — remains largely unclaimed. Applicants targeting global aviation markets should assess whether their filings require broader international prosecution.

Beta Air shapes foundational IP; Denso enters with a drone-equipment emphasis
Two applicants define the current landscape: Beta Air with deep, broad coverage across charging infrastructure and safety systems, and Denso as a new entrant bringing automotive-electronics expertise to airborne platforms.
Beta Air LLC
Beta Air holds 23 patent families — the overwhelming majority of the ranked corpus — concentrated in H02J 7 (power supply and grid systems), B60L 53 (electric vehicle propulsion), and B64F 1 (ground installations for aircraft). This breadth reflects a deliberate strategy to own the full charging stack from grid interface to aircraft-side hardware. Momentum is stable (flat trend versus the prior period), indicating a consolidation rather than acceleration phase.
families: 23Denso Corporation
Denso Corporation enters with 5 patent families, classified as a new entrant with rising momentum. Its technology emphasis differs meaningfully from Beta Air’s: Denso’s focus spans H02J 7 (power supply), B64D 27 (aircraft equipment), and B64U 50 (unmanned aerial vehicles/drones), suggesting a strategy oriented toward electrified aviation components and drone-specific power architectures rather than ground charging infrastructure. Given Denso’s scale in automotive electronics, this entry trajectory warrants monitoring.

Under-served branches adjacent to the core V2G-aircraft space
Several IPC branches appear at low volume within this landscape, representing areas where incumbent IP is sparse. These are observations of relative sparsity; they warrant further diligence before being treated as investment targets.
B64U · Unmanned aerial vehicles (drones)
With only 4 patent records in B64U, drone-specific V2G charging architectures are the least-covered adjacent branch that still has a direct technical connection to the core topic. Denso’s recent entries in B64U 50 confirm that the underlying technical problem — charging autonomous aerial platforms from grid-connected infrastructure — is being recognized, but coverage remains thin. An applicant with UAV-specific charging hardware or swarm-level energy management capabilities could establish early positions before this branch attracts broader interest.
Search this in Eureka →H01M · Batteries, cells & fuel cells
Only 1 patent record appears in H01M within this landscape, suggesting that cell-level battery management and chemistry optimization for electric-aircraft V2G cycles is not yet addressed by incumbent filers. The technical rationale is clear: aviation-grade duty cycles impose distinct charge-discharge demands compared with ground vehicles, and cell-level IP tailored to those requirements would complement existing grid-interface and propulsion claims. Entry would require battery chemistry or BMS expertise but would sit in a largely unclaimed adjacent position.

The landscape contains 28 patent families in scope, with the United States as the dominant filing jurisdiction accounting for 24 of the recorded filings.
Beta Air LLC leads with 23 patent families, representing an overwhelming share of the ranked corpus. Denso Corporation is the only other ranked applicant, holding 5 patent families.
Filing activity was absent from 2017 through 2020. It began in earnest in 2021, which remains the peak annual filing year. Activity has continued at a lower but sustained level since then.
H02J (Power supply and grid systems) is the most prevalent branch, followed by B60L (Electric vehicle propulsion), B64F (Ground installations for aircraft), and B64D (Aircraft equipment). These four classes account for the bulk of recorded coverage.
The field is classified as Growth stage: the recent three-year filing window is 27% above the prior three-year baseline. However, annual volume has eased from its 2021 peak, and the most recent years are further understated by publication lag, so the current pace should not be interpreted as a real decline.
The sparsest branches are B64U (Unmanned aerial vehicles/drones) with 4 records, G07C and G01R with 2 and 1 records respectively, and H01M (Batteries, cells and fuel cells) and H04B (Transmission) each with 1 record. These areas have limited incumbent IP, but any entry decision should be validated against technical feasibility and commercial pathway before being treated as an opportunity.
