EV Battery Pack for Aviation Patent Landscape 2026
GM Global Technology Operations dominates this nascent field with an outsized share of filings among the largest filers, while activity peaked in 2023 and has since eased, leaving the competitive structure highly concentrated in a single incumbent. A small cluster of challengers — primarily university-industry collaborations and EV specialists — hold modest positions, signalling that the landscape remains open to differentiated entrants.
GM Global Technology Operations leads a heavily concentrated field
GM Global Technology Operations LLC holds the top-ranked position by a wide margin, followed by a group of much smaller filers including the University of Toronto (Governing Council), EleapPower Ltd, Elwha LLC, and InvertedPower Pty Ltd.
The top five filers account for 85% of the combined output of the hundred largest filers, indicating extreme concentration with a steep drop-off after the leader. The gap between the first-ranked applicant and all others is structural, not marginal.

GM’s dominance suggests deep prior-art coverage in core EV propulsion and battery management subclasses; any new entrant must either design around this estate or target the adjacent, less-covered branches that GM has not prioritised.
The most recent 18–24 months of filing data are subject to publication lag and therefore under-represent actual recent activity; conclusions about the trajectory of late-period entrants should be treated as provisional. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
Filings peaked in 2023; propulsion IP dominates the technology mix
The annual filing trend and technology composition charts together reveal a field that surged through 2019–2023 and is now consolidating, with electric vehicle propulsion (B60L) accounting for the largest share of classified records.
Annual filing trend
Filings were negligible before 2019, then climbed through 2021, dipped in 2022, surged to a peak in 2023, and have fallen sharply in 2024–2025. Given standard 18–24 month publication lag, 2024 and 2025 figures are materially under-counted and should not be read as a sustained decline.

B60L (electric vehicle propulsion) is the dominant class, followed by H01M (batteries and cells), B60K (vehicle propulsion and drive), H02K (electric motors and generators), and H02J (power supply and grid systems). Classes beyond the top five each represent a small minority of records, pointing to areas of relative sparsity.

What the competitive structure means for R&D investment
Four dimensions — maturity, concentration, collaboration, and geography — define the strategic context for any team evaluating entry or expansion in aviation battery-pack IP.
Field at plateau: past peak, multi-year growth still positive
The lifecycle stage is Maturity, with annual filings having plateaued near their 2023 peak. The ten-year window still shows positive growth of 10%, but the evidence indicates annual volume has eased from that peak rather than continuing to climb. Teams entering now face an established prior-art base rather than a wide-open greenfield.
Lifecycle: MatureSingle-firm dominance creates both a moat and a gap
The top five filers hold 85% of the hundred largest filers’ combined output, with GM Global Technology Operations alone representing a structurally dominant position. This concentration means that broad freedom-to-operate searches must start with GM’s estate. It also means that niche or application-specific subclasses may be underserved relative to the core propulsion classes GM has prioritised.
HHI: Very HighUniversity–industry partnership is the primary co-filing model
The only confirmed co-filing relationship in evidence is between the Governing Council of the University of Toronto and EleapPower Ltd, who jointly hold 6 patent families. This academic–startup pairing suggests that foundational battery-integration research in this domain is being commercialised through close university–industry linkage rather than large-company consortia. Other applicants appear to file independently.
Co-filer: Toronto–EleapPowerUnited States is the primary filing jurisdiction by a wide margin
The United States accounts for the largest concentration of records, followed at a much lower level by Europe (EPO), WIPO (PCT), Germany, India, and Canada. The limited PCT and EPO coverage relative to US filings suggests that international protection strategies in this space remain underdeveloped, which may represent an opportunity for applicants seeking multi-jurisdiction coverage.

Co-filing pairs, ranked by the number of jointly-filed patent families.
GM leads; university–startup alliance and EV specialists are the closest challengers
The applicant landscape has a clear two-tier structure: a dominant incumbent far ahead of a loosely clustered group of much smaller filers, several of which are recent entrants.
GM Global Technology Operations LLC
GM Global Technology Operations holds 124 patent families — more than twenty times the next-ranked filer — making it the unambiguous incumbent. Its technology emphasis spans B60L 50 (EV propulsion), B60L 53 (charging), and B60K 1 (vehicle propulsion and drive). Recent-period momentum is up 14% versus the prior three-year window, confirming continued investment rather than harvest mode.
families: 124Governing Council of the University of Toronto & EleapPower Ltd
The University of Toronto (Governing Council) and EleapPower Ltd each hold 6 patent families and file jointly, forming the field’s only confirmed co-filing partnership. Their shared focus on B60L 50, B60L 58, and H01M 16 indicates a concentration on battery-integration and state-of-health monitoring subclasses. Both are classified as new entrants in recent-period momentum data, suggesting the collaboration is still in early commercial development.

Under-served IPC branches adjacent to the dominant propulsion cluster
Several IPC classes appear at lower filing volumes relative to the dominant B60L propulsion class, indicating potential areas of relative sparsity. These observations reflect current filing density and should be evaluated against technical relevance and freedom-to-operate before treating them as actionable opportunities.
H02M · Power Conversion (AC/DC)
H02M (power conversion including DC-DC and inverter technology) accounts for a small share of records in this landscape despite being technically central to aviation battery-pack integration, where voltage transformation between pack and motor/grid interfaces is a critical design challenge. The relatively low filing count suggests that aviation-specific power electronics architectures remain an under-served branch. Teams with expertise in high-voltage DC-DC or bidirectional converters could establish positions here with targeted filings.
Search this in Eureka →H02P · Control of Motors & Generators
H02P (control of electric motors and generators) appears at a low count relative to the propulsion and battery classes that dominate the corpus. For aviation applications where precise motor control under varying altitude, temperature, and load conditions is safety-critical, this subspace has plausible high value. The low current density relative to adjacent classes suggests the aviation-specific control algorithms and fault-tolerant motor management layer is not yet heavily claimed, offering a potential entry path for power electronics and flight-system control specialists.

Frequently asked questions
The landscape contains 149 patent families in scope. Activity began in earnest from 2019 onward, with a peak in 2023.
GM Global Technology Operations LLC is the clear leader with 124 patent families, more than twenty times the volume of the next-ranked applicants. Its focus spans electric vehicle propulsion (B60L 50, B60L 53) and vehicle drive systems (B60K 1).
The field is assessed as Mature, with annual filings having plateaued near the 2023 peak. The ten-year window still shows positive growth, but annual volume has eased from that peak. This means the prior-art base is substantial and rapidly growing white space is limited.
The United States is the dominant filing jurisdiction, followed at much lower levels by Europe (EPO), WIPO (PCT), Germany, India, and Canada. International coverage through PCT and EPO routes appears limited relative to the US concentration.
The only confirmed co-filing relationship in evidence is between the Governing Council of the University of Toronto and EleapPower Ltd, who jointly hold 6 patent families focused on battery-integration and state-of-health monitoring subclasses. No large-company consortium co-filings are evident in the data.
H02M (power conversion, including DC-DC and inverter technology) and H02P (control of motors and generators) show lower filing counts relative to the dominant B60L propulsion class. Both are technically relevant to aviation-specific battery-pack design. B60W (hybrid and joint vehicle control) is also sparsely covered. These should be validated against freedom-to-operate analysis before treating them as confirmed white space.
