EV Fast Charging for Commercial Trucks Patent Landscape
The patent corpus for EV fast charging in commercial trucks is extremely nascent, with only 3 patent families on record and all activity concentrated in the United States. Siemens AG and Rivian are the only named institutional filers to date, and the field shows no signs of deep prior-art density, signaling an early-stage arena with wide-open technical territory.
Siemens AG leads a near-empty field
Siemens AG holds the top rank with 2 patent families, followed by Rivian Holdings LLC with 1. These two organizations account for the entirety of the current corpus.
The top five filers’ share of the ranked applicants visible in this query stands at 100%, which in this case reflects a corpus so small that only two applicants appear in the ranking — there is effectively no second tier.
| # | Applicant | Patent families | Share |
|---|---|---|---|
| 1 | Siemens AG | 2 | |
| 2 | Rivian Holdings LLC | 1 |
Siemens AG’s lead position, built on B60L electric-vehicle propulsion and H02M power-conversion filings, suggests early framing of the hardware and power-electronics layer. Rivian’s single family signals that vehicle OEMs are beginning to stake positions, but neither player has yet established a defensive portfolio depth.
Activity recorded after mid-2024 is subject to normal patent-publication lag and may be under-counted; the current totals should be treated as a floor rather than a ceiling. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
Filing activity started only in 2022 and the technology mix is tightly clustered
The annual trend and IPC composition together reveal a field that is embryonic both in volume and in technical scope, with all filings concentrated in a narrow set of electrification classes.
Annual filing trend
No families were recorded before 2022. A single family appeared in 2022, followed by two in 2023. Years from 2024 onward show zero at present, but this reflects publication lag rather than a cessation of activity; any filings from late 2023 onward are likely still pending publication.

B60L (electric vehicle propulsion) is visible in with 3 records, flanked by H02J (power supply and grid systems) and H02M (power conversion) each with 2 records. The absence of thermal management, connector-standards, or communication-protocol classes highlights how narrowly defined the current prior art is.

Bi-directional power converter
A bi-directional power converter, a control unit, a charging device and a method for transferring power between an EV and a power grid are provided. The bi-directional power converter includes an isolated DC-DC converter having a first stage converting a DC voltage into a high frequency AC voltage, a second stage, having four power conversion switches and… (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.

Some patent titles may be shown in their original, non-English language where an accurate translation could not be guaranteed.
What the structure means for R&D investment decisions
Three data points limit statistical confidence, but the structural signals are clear: this is an uninhabited patent space where first-mover filing can define the prior-art landscape.
Embryonic stage — field effectively begins in 2022
The lifecycle evidence shows no stage classification is yet possible given the tiny corpus, but all observable filing occurred between 2022 and 2023. The technology has not yet accumulated the density of prior art typical of a growth-phase field. Teams entering now would be writing foundational claims rather than navigating a crowded landscape.
Early-stageTwo filers hold all known IP; the field is structurally open
Siemens AG and Rivian Holdings LLC together account for 100% of the ranked families. This extreme concentration is a function of low total volume rather than deep entrenchment by incumbents. No single player has built a blocking portfolio, meaning late entrants face minimal freedom-to-operate risk from existing grants at this stage.
High concentration, low depthNo co-applicant activity detected
Evidence pending — the collaboration data shows no co-filed or jointly assigned families in the current corpus. The absence of university, national-lab, or OEM-supplier co-filings may reflect the field’s novelty rather than a structural preference for solo filing. Watching for consortium or joint-development agreements would be a leading indicator of the next filing wave.
No co-filings yetAll activity anchored in the United States
All 3 patent records are filed at the United States Patent and Trademark Office. No European, Chinese, or other jurisdictional coverage is visible in the current corpus. For teams with global commercial ambitions, PCT or direct national filings in the EU and China represent an open geographic flank that no current filer has addressed.

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.
Siemens AG
Siemens AG holds 2 patent families and entered the corpus as a new entrant, with its most recent filing period showing 1 family recorded. Its technical emphasis spans B60L 53 and B60L 55 (EV propulsion charging infrastructure) and H02M 3 (DC power conversion), pointing to a hardware and power-electronics framing consistent with Siemens’ broader grid and charging infrastructure business.
families: 2Rivian Holdings LLC
Rivian Holdings LLC holds 1 patent family and also entered as a new entrant. Its technical focus covers B60L 53 (charging interface) alongside H02J 1 and H02J 3 (power supply and grid systems), suggesting an OEM-side interest in vehicle-grid integration rather than pure charging hardware — a complementary angle to Siemens’ converter-centric approach.
families: 1Frequently asked questions
The current corpus contains 3 patent families. This is a very small corpus, and given normal patent-publication lag, filings from late 2023 onward may not yet appear.
Siemens AG leads with 2 patent families. Rivian Holdings LLC holds 1 patent family. These are the only two institutional filers currently ranked in the corpus.
All 3 patent records are filed in the United States. No filings in European, Chinese, or other jurisdictions appear in the current corpus.
The first recorded filing appeared in 2022, with 2 additional families filed in 2023. No activity was recorded before 2022 in the data window reviewed.
B60L (electric vehicle propulsion and charging) covers all 3 records. H02J (power supply and grid systems) and H02M (power conversion) each cover 2 records. Thermal management, communication protocols, and connector-standard classes are absent.
The extremely low prior-art density and absence of filings in adjacent technical branches — such as thermal management and charging communication protocols — suggest wide freedom to operate and room for foundational claims. However, teams should conduct a full freedom-to-operate search against broader databases before concluding the field is unencumbered, as the current corpus is narrow in scope.

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.
