Patent Landscape · Automotive & EV SystemsCharging Infrastructure Patents: Who's Filing, What They Claim
- Filings nearly doubled in three years: documented growth of +127% from 357 records in 2021 to 810 in 2024, the last complete filing year in this dataset.
- The field is not consolidated: the leader holds 220 records but the top 5 combined account for just 17.1% of all 4,484 records in scope, with a long tail behind them.
- Two IPC subclasses dominate claim space: B60L (electric vehicle propulsion) touches 64.1% of records and H02J (power supply & grid systems) touches 41.7%, leaving software and communications classes comparatively open.

Leading Jurisdiction
Filing growth compares 2021 (357 records) with 2024 (810) — a three-year span. 2024 is the most recent year we treat as complete: publication lags filing by roughly 18 months, so 2025 onwards are still filling in and any growth rate that ends there would understate the field. Top-5 share is the combined record count of the five largest assignees divided by all 4,484 records in scope (CR5), not by the ranked leaders only.

Overview
What this landscape covers
This landscape draws on 4,484 published records filed between 2015 and the 2026 data cut-off, matched against charging infrastructure terms alongside vehicle control, battery state and grid-facing language. That combination pulls in filings from vehicle OEMs, charging equipment specialists, university research arms and a growing group of software and AI-heavy entrants, rather than isolating one narrow charging connector or protocol claim type. Because publication typically lags filing by around eighteen months, the most recent filing year in the trend is understated and should not be read as a slowdown.
Records here span propulsion and battery hardware, grid-facing power electronics, and a rising share of business-process and communications classes — a mix that suggests charging infrastructure is being claimed as much through control and data layers as through connectors and power hardware.

The data
Filing trends and technology composition
Two views of the same 4,484-record set: how filing volume has moved year on year, and which IPC subclasses carry the claim density.
Filing trend
Filings rose from 108 in 2017 to a documented peak of 810 in 2024, with growth of +127% across 2021-2024 alone. 2026 shows 228 so far but is still an incomplete filing year — treat the tail end of the curve as a floor, not a ceiling.
Technology composition
B60L and H02J between them touch the majority of records, reflecting the field's roots in propulsion and power-supply hardware. G06Q's 15.5% share signals a meaningful move toward billing, scheduling and commerce-layer claims sitting alongside the hardware.
Shares are the percentage of the 4,484 records in scope. A patent can carry several IPC classes, so the shares add up to more than 100%.

WO2020069517A2 — Intelligent transportation systems
STRONG FORCE INTELLECTUAL CAPITAL, LLC
Transportation systems have artificial intelligence including neural networks for recognition and classification of objects and behavior including natural language processing and computer vision systems. The transportation systems involve sets of complex chemical processes, mechanical systems, and interactions with behaviors of operators. System-level interactions and behaviors are classified, predicted and optimized using neural networks and other artificial intelligence systems through selective deployment, as well as hybrids and combinations of the artificial intelligence systems, neural networks, expert systems, cognitive systems, genetic algorithms and deep learning.Filed by Strong Force Intellectual Capital, LLC, this application frames charging and transportation infrastructure as an AI-classification problem rather than a power-hardware one — a claim style that sits outside the B60L/H02J core and is worth checking before building control-layer software.

What the numbers mean for a filing decision
Read together, the concentration, growth and IPC figures point to where claim space is already dense and where it is still open.
Concentration
17.1%
of 4,484 records held by the top 5
No single owner controls the field
The leader holds 220 records, but the top 5 combined reach only 17.1% of all 4,484 records in scope and the top 10 only 22.9%. That is a fragmented landscape rather than a gated one — freedom-to-operate risk concentrates on specific claim clusters, not on a single blocking owner.
Based on the full 100-company assignee ranking
Growth
+127%
filing growth, 2021 to 2024
Filing activity roughly doubled in three years
Volume moved from 357 records in 2021 to 810 in 2024, the last year that can be treated as complete given publication lag. Growth of this pace usually means the underlying claim space is filling quickly, which is a reason to check freedom-to-operate now rather than after another filing cycle.
2024 is the most recent complete filing year
Composition
64.1%
of records touch B60L
Propulsion and power hardware still anchor the field
B60L and H02J together cover the large majority of records, meaning core electric-vehicle propulsion and grid-facing power supply claims remain the densest zones. Software-adjacent classes such as G06Q, G06F and H04L sit well behind at single-digit-to-mid-teens shares, which is where claim space is comparatively less occupied.
Shares sum above 100% because records can carry multiple IPC classes
Jurisdiction
1,775
records at the US receiving office
Filing activity is US- and India-heavy
The United States receives the largest share of filings at 1,775 records, with India second at 1,113 — well ahead of Europe, WIPO/PCT, the UK and Canada. That distribution matters for where enforcement and licensing risk is most likely to surface first.

YoY for several leaders
Leader-year momentum looks flat, not falling
Several of the highest-volume assignees show 0 filings and -100% year-over-year in the latest year. Given the roughly 18-month publication lag, this reads as an artefact of incomplete recent-year data rather than an actual pullback in activity.

Non-traditional filers are present
Alongside automakers and a university technology-transfer body, at least one AI-and-intellectual-property holding entity appears among the ranked leaders, filing systems-level claims that frame charging and transportation as a data and control problem rather than a hardware one.

What's next
Where to take this analysis
The figures above establish scale and shape; the next step is testing specific claim language against them.
Check freedom-to-operate on a specific claim
Concentration is low at the top, but that does not mean any given claim is clear — the risk sits in dense sub-clusters within B60L and H02J rather than with a single dominant owner.
Explore claim-level search in EurekaTrack the under-claimed branches before they fill
Load-balancing scheduling, V2G billing and depot orchestration carry lighter documented claim density today; filing growth elsewhere suggests that gap will not stay open indefinitely.
Monitor white space in EurekaWatch momentum, not just the latest year
Because publication lags filing by around 18 months, judge recent-year activity against the 2021-2024 trend rather than the partial 2025-2026 figures alone.

FAQ
Common questions on the charging infrastructure patent landscape
The leading assignee in this dataset holds 220 of the 4,484 records in scope, with fifth place at 95 and tenth place at 44. That drop-off is steep at the very top but the field is not tightly held overall: the top 5 assignees combined account for only 17.1% of all records, and the top 10 for 22.9%. In practice this means no single company controls charging infrastructure claim space, and competitive tracking needs to cover a long tail of mid-size and single-filing entrants, not just the largest filer.
It is growing. Documented filings rose from 357 records in 2021 to 810 in 2024, a growth rate of +127% over that three-year span, and 2024 is the most recent year that can be treated as a complete filing year. Figures for 2025 and 2026 appear lower, but that reflects the roughly 18-month lag between filing and publication rather than an actual slowdown, so those later years should not be read as a peak having passed.
B60L, covering electric vehicle propulsion, touches 64.1% of the 4,484 records in scope, and H02J, covering power supply and grid systems, touches 41.7%. Business-process classes like G06Q sit further behind at 15.5%, with battery, digital-processing and wireless-communication classes each in the single-to-high single digits. Because a single record can carry multiple IPC classes, these shares add up to more than 100% and should be read as claim density per class, not as a breakdown of the total.
The densest claim space sits in propulsion hardware (B60L) and grid-facing power electronics (H02J), which together cover the majority of records. Adjacent branches such as dynamic load-balancing scheduling, vehicle-to-grid billing protocols, wireless charging control and fleet depot orchestration carry comparatively lighter documented density and are worth checking specifically before assuming they are occupied. High density in the core classes does not mean the technology itself is mature — it means that particular claim space is crowded.
The United States receives the most filings in this dataset at 1,775 records, followed by India at 1,113. Europe via the EPO, the WIPO/PCT route, the United Kingdom and Canada each receive smaller shares, in that order. This distribution is useful for prioritising where enforcement risk and competitive filings are most likely to concentrate first.
