EV Battery Pack for Agricultural Vehicles Patent Landscape
With only 7 patent families in scope, this is a nascent, highly concentrated field where GM Global Technology Operations holds the largest single position and the top five filers together account for the dominant share of the hundred largest filers. The field is still expanding on a multi-year basis, though annual volume has eased from its 2023 peak and the most recent period is further understated by publication lag.
GM Global leads a field with very few active filers
GM Global Technology Operations LLC holds the top position with 2 patent families, placing it clearly ahead of a group of five rivals — Volvo Truck Corp, INT Truck Intprop Co LLC, MR Nanjaiah Lakkanna Gowda, MR Suresh Nanjaiah, and Ramakrishnan Ram Mohan — each with 1 patent family.
Concentration is extreme: the top five filers account for 86% of the combined output of the ranked applicants visible in this query. The tier gap between the leader and all challengers is, at this corpus size, effectively a two-to-one margin — a small advantage that could be erased by a single new filing.

GM’s position signals early-mover activity in battery-pack integration for agricultural or heavy-duty off-road applications, but the overall corpus is too small to infer sustained strategic commitment from any single applicant; the landscape remains open to new entrants.
The most recent one-to-two years are likely under-counted due to standard patent publication lag; the true recent activity level is probably higher than the trailing data suggest. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
A 2023 activity spike dominates a sparse, multi-year trend; propulsion IP anchors the technology mix
The annual filing chart reveals an uneven but upward multi-year trajectory punctuated by a 2023 peak, while the technology composition chart shows that electric-vehicle propulsion (B60L) is by far the visible IPC branch, with battery chemistry and power-supply branches as secondary nodes.
Annual filing trend
Filings were sporadic from 2017 through 2022 — at most one family per year — before rising to three families in 2023. The subsequent drop in 2024 and the zero readings for 2025–2026 should be read cautiously: publication lag routinely depresses counts in the most recent 18–24 months, so actual recent activity is likely higher than shown.

B60L (electric vehicle propulsion) appears across all 7 patent families, establishing it as the visible technical anchor. H01M (batteries, cells and fuel cells) and H02J (power supply and grid systems) each appear in 2 families, reflecting a secondary focus on cell-level chemistry and charging infrastructure. The remaining branches — B60K, B60W, F03D, F16H, G01R, and H02K — each appear in only 1 family, indicating broad but shallow coverage of drivetrain integration, hybrid control, measurement, and energy-conversion sub-topics.

What the competitive structure means for R&D investment
A 7-family corpus in a Growth lifecycle stage signals that the technology is commercially credible but strategically undercrowded, offering genuine first-mover potential for well-resourced entrants who move quickly.
Growth stage — expanding multi-year, eased from 2023 peak
The lifecycle is classified as Growth, driven by a 400% uplift in the recent three-year window relative to the prior three-year window. Annual volume peaked in 2023 and has eased since, though publication lag means recent filings are under-represented. For R&D planners, this stage means core concepts are being staked out now, and early filings can anchor a broad claim landscape before the field matures.
Growth stageHighly concentrated but fragile — a single filing shifts rankings
The top five filers hold 86% of the combined output of the ranked applicants visible in this query, and GM Global leads with 2 patent families against rivals each holding 1. At this corpus size, concentration figures are sensitive: one new filing by any challenger immediately redistributes share. The practical implication is that no applicant has yet built a defensible blocking position.
High concentrationNo co-applicant activity detected
The collaboration evidence shows no co-filed families in the corpus. All filings are single-assignee, suggesting that the field has not yet attracted the consortium or university-industry partnerships common in more mature EV sub-sectors. This creates an opportunity for strategic alliances — particularly between OEMs and agricultural-equipment makers — to establish joint IP positions before the field crowds.
No co-filingsUS-centric filing with early India and EPO presence
The United States leads with 3 patent records, followed by India with 2, and Europe (EPO) and WIPO (PCT) with 1 each. India’s presence — tied to individual inventors Nanjaiah Lakkanna Gowda and Suresh Nanjaiah — points to grassroots innovation activity in a major agricultural market. The PCT filing signals at least one applicant seeking multi-jurisdictional coverage, but systematic filing in key agricultural markets such as the EU, Brazil, or China has not yet materialized based on current evidence.
US + India + EPOGo beyond the landscape: Eureka’s TRIZ Solution agent breaks down an R&D problem and returns patented concept solutions, each with a technical approach and cited patent & literature evidence.

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.
GM Global Technology Operations LLC
Holds 2 patent families — the largest single position in the corpus. Technology emphasis spans H01M (batteries and fuel cells) at the cell level and B60L (electric vehicle propulsion) for vehicle-level safety and energy management. Momentum is flagged as a new entrant, indicating this activity represents an initial staking of ground rather than a sustained multi-year program. The combination of chemistry-level and system-level claims gives GM the broadest current scope in the field.
patent families: 2Volvo Truck Corp
Holds 1 patent family concentrated in B60L (electric vehicle propulsion), signaling interest in electrified heavy-duty or agricultural powertrain integration. Momentum is also flagged as a new entrant. As a commercial vehicle OEM with existing electric truck programs, Volvo’s entry into this adjacent agricultural-vehicle space — even at one family — is a notable signal worth monitoring for follow-on filings.
patent families: 1Frequently asked questions
The corpus contains 7 patent families in scope. This is a very small corpus, reflecting the early-stage nature of dedicated IP activity in this specific application area.
GM Global Technology Operations LLC leads with 2 patent families. All other applicants — Volvo Truck Corp, INT Truck Intprop Co LLC, MR Nanjaiah Lakkanna Gowda, MR Suresh Nanjaiah, and Ramakrishnan Ram Mohan — each hold 1 patent family.
The field is classified as Growth. The recent three-year filing window is 400% above the prior three-year window on a multi-year basis, though annual volume eased from its 2023 peak. Publication lag means the most recent period is likely under-counted.
The United States leads with 3 patent records, followed by India with 2, and Europe (EPO) and WIPO (PCT) with 1 each. Systematic coverage of other major agricultural markets such as Brazil, China, or the broader EU has not been evidenced in the current corpus.
No co-applicant filings are present in the corpus. All 7 patent families are single-assignee, indicating the field has not yet attracted consortium or cross-industry partnerships.
Five branches — B60K (vehicle propulsion and drive), B60W (hybrid/joint vehicle control), F03D (wind motors), F16H (gearing and transmissions), and G01R (electric and magnetic measurement) — each appear in only 1 patent family. B60W and G01R are particularly notable as technically relevant to agricultural EV battery management yet sparsely covered.
