Compact High-Density E-Drive Patent Snapshot 2026
The compact high-density e-drive patent space is nascent, with just 6 patent families on record, all concentrated in a single filing year (2023) and split equally among three applicants. Activity is highly fragmented at the top, with vehicle propulsion and drive (B60K) accounting for the entirety of indexed filings.
Three applicants share the field equally — concentration is absolute but the corpus is very small
Electric Propulsion Technologies LLC, Neapco Intellectual Property Holdings LLC, and Mahindra & Mahindra Ltd each hold 2 patent families, jointly accounting for the full corpus of 6 patent families in scope. No single applicant has established a commanding lead.
The top five filers account for 100% of the ranked applicants visible in this query’ combined total — an extreme concentration figure that reflects the field’s early stage rather than any strategic lock-in by incumbents. The tier gap between any two applicants is effectively zero at this scale.
| # | Applicant | Patent families | Share |
|---|---|---|---|
| 1 | Electric Propulsion Technologies LLC | 2 | |
| 2 | Neapco Intellectual Property Holdings LLC | 2 | |
| 3 | MAHINDRA & MAHINDRA LTD | 2 |
The three leaders’ equal positions suggest that no organization has yet committed sustained R&D to differentiate through IP volume. First-mover advantage remains available to any applicant willing to build a denser portfolio in this space.
The most recent filing years should be treated as under-counted due to standard patent publication lag; the apparent absence of activity after 2023 does not reflect the actual current state of filings. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
All indexed activity originates from a single year, dominated by vehicle propulsion classification
The filing trend and technology composition together reveal a field that has just begun to form a patent record, with all 6 families appearing in 2023 and the IPC mix tightly anchored to vehicle propulsion and drive.
Annual filing trend
All 6 patent families were filed or published in 2023; years before and after show zero indexed activity. The 2024–2026 window must be treated as incomplete due to publication lag — absence of records in those years does not confirm a halt in filings.

B60K (vehicle propulsion and drive) covers all 6 records, establishing it as the defining classification for this topic. B60B (vehicle wheels and tyres) and F16H (gearing and transmissions) each appear in 2 records, indicating that integration with wheel-end hardware and transmission architecture is a secondary but consistent technical theme.

Compact e-axle assembly
An e-axle assembly includes a housing extending from a first housing end to a second housing end to define an internal compartment. At least one electric motor is disposed in the internal compartment and includes a stator and a rotor rotatable relative to the stator about an axis. The rotor defines a hollow extending internally within the rotor, and at… (excerpt from the patent abstract)

Ranked by total forward citations. Citation counts favour older and broadly cited patent families, and broad or adjacent patents may appear when they match the search scope. Treat this section as citation context, not as a curated list of the most topic-specific patents. Some patent titles may be shown in their original, non-English language where an accurate translation could not be guaranteed.
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.
Electric Propulsion Technologies LLC
Holds 2 patent families, all concentrated in B60K 17 (vehicle propulsion and drive) and B60B 35 (vehicle wheels and tyres), with additional coverage in B60K 1. Marked as a new entrant in applicant momentum data, indicating its entire record was established recently. The wheel-end and propulsion combination suggests a focus on integrated e-axle or in-wheel motor architectures.
families: 2Mahindra & Mahindra Ltd
Also holds 2 patent families, with IPC focus on B60K 17, B60K 6 (hybrid propulsion), and F16H 1 (gearing). Also flagged as a new entrant. The hybrid propulsion classification (B60K 6) distinguishes Mahindra’s technical emphasis from the pure-electric focus suggested by Electric Propulsion Technologies LLC, pointing toward electrified powertrain integration for hybrid platforms.
families: 2Frequently asked questions
The indexed corpus contains 6 patent families in scope. All were filed or published in 2023, and the recent years should be treated as potentially under-counted due to publication lag.
Electric Propulsion Technologies LLC, Neapco Intellectual Property Holdings LLC, and Mahindra & Mahindra Ltd each hold 2 patent families, making them co-equal leaders with no single visible filer.
B60K (vehicle propulsion and drive) covers all 6 indexed records. B60B (vehicle wheels and tyres) and F16H (gearing and transmissions) each appear in 2 records as secondary classifications.
The United States and WIPO (PCT) each account for 2 patent records. Europe (EPO) and India each account for 1 record. No filings are evidenced in China, Germany, Japan, or other major manufacturing markets within this corpus.
The lifecycle stage cannot be formally classified from current evidence given the very small corpus size and single-year filing concentration. The field is best characterized as embryonic, with no sustained multi-year filing trend yet established.
No co-applicant or co-filing relationships are recorded in the current evidence. The three active filers appear to be pursuing independent strategies without documented cross-organizational collaboration.

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.
