Electric Drivetrain for Mining Trucks Patent Landscape
A small but fast-expanding corpus of 31 patent families is dominated by ABB (Schweiz) AG, which holds nearly two-thirds of the top filers’ output; the field grew 113% on a recent three-year basis, though annual volume has eased from its 2022 peak. Concentration is extreme and adjacent branches—navigation, non-electric control, and power supply—remain thinly covered, signalling clear openings for challengers.
ABB leads an extremely concentrated, early-stage field
ABB (Schweiz) AG leads the ranking with 19 patent families, followed by Behault Industrial Property Office BV with 8 and Caterpillar Inc with 4. The top three applicants account for the entire top-ranked filer pool, reflecting a field where a handful of actors have established essentially all documented intellectual property.
The top five filers collectively represent 100% of the hundred largest filers’ combined total, confirming extreme concentration with no meaningful second tier. The gap between ABB’s 19 patent families and the next-largest filer’s 8 is substantial and implies that ABB has a structurally different commitment to this space.
| # | Applicant | Patent families | Share |

| 1 | ABB (Schweiz) AG | 19 | |
| 2 | Behault Industrial Property Office BV | 8 | |
| 3 | Caterpillar Inc | 4 |
ABB’s dominant position across core electric-vehicle-propulsion sub-classes suggests it has built a broad foundational portfolio, while Behault IND Property Office BV and Caterpillar Inc occupy narrower, more specialised niches. New entrants would need either differentiated technology or a focus on under-covered adjacent branches to avoid direct opposition.
The most recent 18–24 months of filings are likely understated due to standard patent publication lag; activity through 2025–2026 should be interpreted cautiously. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
A 2022 filing surge defined the field; propulsion dominates the technology mix
Filing activity was negligible before 2020, surged sharply to a peak in 2022, and has moderated since on an annual basis—though the multi-year growth rate remains strongly positive. The technology mix is overwhelmingly weighted toward core electric-vehicle-propulsion classes, with adjacent control and navigation branches underrepresented.
Annual filing trend
The trend shows zero activity in 2017–2019, a ramp beginning in 2020, a clear annual peak of 12 patent families in 2022, and lower but still positive volumes in subsequent years. The 2024–2025 figures are understated by publication lag and should not be read as a sustained decline; the three-year recent window is still 113% above the prior window.

B60L (Electric vehicle propulsion) accounts for 31 patent records and is by far the dominant class, followed by B60W (Hybrid/joint vehicle control) at 13. G01C (Distance, navigation and gyroscopes), G05D (Control of non-electric variables), and H02J (Power supply and grid systems) each contribute only 1–2 records, highlighting how thinly the supporting technology layers are covered relative to the propulsion core.

A method of determining a road surface condition is described. The method includes providing an electric power to a vehicle while the vehicle travels on the road, determining at least one power delivery value, the power delivery value being indicative of a power provided to the vehicle along the road, correlating the power delivery value with the position… (excerpt from the patent abstract)

What the landscape structure means for R&D investment decisions
The combination of strong multi-year growth, extreme applicant concentration, and sparse adjacent-branch coverage creates a clearly stratified opportunity map for R&D planners.
Growth stage, post-2022 peak
The lifecycle evidence places this field in the Growth stage. Recent three-year filings sit well above the prior three-year window—a 113% increase—confirming the field is still expanding on a multi-year basis. However, annual volume has eased from its 2022 peak, and the most recent years are further understated by publication lag, so the moderation is partly a data artefact. Entrants should expect a still-forming IP landscape rather than a mature, densely covered one.
Growth · post-2022 peakExtreme: one dominant player, two distant followers
ABB (Schweiz) AG holds 19 of the 31 patent families in scope, and the top five filers account for 100% of the hundred largest filers’ combined total. This level of concentration is rare and signals that ABB has set an early foundational position. Challengers—including Caterpillar Inc with 4 patent families—have limited overlap with ABB’s core propulsion sub-classes, suggesting room for differentiated IP if pursued in adjacent or specialised branches.
High concentrationNo co-applicant activity detected
The collaboration evidence shows no co-filed patent families among the ranked applicants. All identified players appear to be filing independently, suggesting the ecosystem has not yet formed the cross-industry or academic partnerships that typically emerge in more mature electrification domains. This absence may represent an opportunity for consortium or joint-development arrangements, particularly between mining operators and drivetrain OEMs.
No co-filing detectedAustralia leads; PCT and mining-nation filings prominent
Australia is the lead jurisdiction with 6 patent records, followed by WIPO PCT filings at 5, Canada at 4, Chile (CL) at 4, and Europe (EPO) at 4. South Africa and Peru each register 2 records. This jurisdiction spread maps closely to major open-cut mining geographies, indicating that applicants are filing strategically in end-use markets rather than primarily in domestic home offices. The United States, at 3 records, is less prominent than might be expected.

ABB anchors core propulsion; Behault and Caterpillar occupy specialised niches
All three ranked applicants are recent entrants to this specific field, consistent with the corpus’s post-2020 origin. Their technology emphases diverge meaningfully, reducing direct head-to-head overlap.
ABB (Schweiz) AG
ABB holds 19 patent families—more than twice the next-ranked filer—concentrated in B60L sub-classes covering electric vehicle propulsion control, current collection, and charging (B60L15, B60L5, B60L53, each with 6 records). Momentum data marks ABB as a new entrant to this specific corpus with 13 recent-window patent families, meaning the bulk of the portfolio was filed in the most recent three-year window. This pattern suggests a deliberate, rapid build-out of foundational propulsion IP.
families: 19Behault Industrial Property Office BV
Behault holds 8 patent families, focused on B60L58 (battery/energy-storage management, 7 records) and B60W20 (hybrid/joint vehicle control, 7 records)—a pairing that points to hybrid and battery-system integration rather than pure drivetrain propulsion. Momentum is also flagged as a new entrant with 3 recent-window families. Individual inventors Ejzenberg Geoffrey and Jans Noel appear in the same B60L58/B60W20 combination, suggesting Behault may be the holding vehicle for individual-inventor IP in this niche.

Navigation, non-electric control, and power supply are under-served adjacent branches
Three IPC branches adjacent to the dominant propulsion core each account for 4% or less of patent records. Their sparsity is an observation of relative underrepresentation; where plausible technical value and entry paths exist, they are noted below.
G01C · Distance, navigation & gyroscopes
Only 2 patent records fall under G01C, representing 4% of the corpus. For autonomous and semi-autonomous mining trucks—where precise localisation in GPS-degraded underground or pit environments is operationally critical—navigation IP is a technically valuable complement to drivetrain control. Caterpillar Inc is the only ranked applicant with G01C21 records (2 records), suggesting the branch is open for specialists in mine-environment localisation or sensor fusion. Entry could leverage existing autonomous-vehicle navigation IP adapted for mining duty cycles.
Search this in Eureka →H02J · Power supply & grid systems
H02J accounts for only 1 patent record (2% share), despite the operational importance of mine-site power infrastructure—charging depots, trolley-assist overhead lines, and energy recuperation from downhill haul cycles. This branch is thinly covered relative to its technical relevance and is an under-served area where power-electronics or grid-integration specialists could establish positions without direct conflict with ABB’s core B60L portfolio. The mining industry’s shift toward renewable-powered mine sites adds further practical relevance to grid-interface IP.
