EV Fast Charging for Recreational Vehicles Patent Landscape
The patent space for EV fast charging applied to recreational vehicles is nascent, with only 6 patent families on record and four distinct applicants — Plug P2P Inc, Mercedes-Benz Research & Development North America, David Albert Sirieix, and Winnebago Industries — sharing the entire corpus. Filing activity is in a growth stage, concentrated almost entirely in the United States, signaling an early-mover window for entrants with differentiated technical approaches.
Four applicants divide a nascent, US-centric corpus
The visible assignee structure is extremely concentrated: Plug P2P Inc and Mercedes-Benz Research & Development North America each hold 2 patent families, while David Albert Sirieix and Winnebago Industries each hold 1, together accounting for the entire corpus of 6 patent families.
The top five filers hold 100% of the combined total among the ranked applicants visible in this query, confirming there is no meaningful second tier — every active participant is effectively a leader by default in this space.
| # | Applicant | Patent families | Share |
|---|---|---|---|
| 1 | Plug P2P Inc | 2 | |
| 2 | MERCEDES-BENZ RES & DEV NORTH AMERICA | 2 | |
| 3 | David Albert Sirieix | 1 | |
| 4 | Winnebago Industries | 1 |
The presence of a peer-to-peer EV charging start-up (Plug P2P Inc), a major OEM R&D arm (Mercedes-Benz R&D North America), an independent inventor (Sirieix), and an established RV manufacturer (Winnebago) signals that the field is being approached simultaneously from infrastructure, vehicle, and product angles, with no single actor yet establishing a visible position.
The most recent 18–24 months of filings are likely under-represented due to standard patent publication lag; 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.
Activity is rising from a near-zero base, led by electric-propulsion filings
The annual filing trend and technology composition together reveal a field that began generating activity only around 2020 and remains in early formation, with electric-propulsion patents showing visible activity in the technology mix.
Annual filing trend
Recorded filings first appeared in 2020 (2 families), fell quiet in 2021–2022, then resumed in 2023–2024 with additional entries. The 50% recent-window growth rate confirms expansion from a small base. Activity in 2025–2026 is understated by publication lag and should not be interpreted as a slowdown.

B60L (Electric vehicle propulsion) accounts for all 6 patent records and is the clear primary branch. H02J (Power supply & grid systems) appears in 3 records, reflecting charging-infrastructure concerns. B60K (Vehicle propulsion & drive) covers 2 records, while H01B (Cables, conductors & insulators) has only 1, marking it as an underserved adjacent area.

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
A nascent corpus, minimal competition, and a single visible jurisdiction create both opportunity and risk: first-mover advantage is achievable, but market validation remains limited.
Growth stage: activity expanding from a near-zero base
The lifecycle assessment classifies this field as Growth, with annual filings still rising and the 50% recent-window growth rate confirming upward momentum. Because the corpus stands at only 6 patent families, entrants can still establish foundational positions without navigating a dense prior-art thicket. The 2020 filing spike was followed by a quiet period before renewed activity in 2023–2025, consistent with early-market uncertainty rather than sustained saturation.
Growth stageExtreme concentration across four applicants with no visible leader
All four active applicants are effectively co-leaders: the top five filers’ share of the ranked applicants visible in this query is 100%, and no applicant has opened a meaningful gap over the others. This absence of an entrenched incumbent lowers the barrier for a new entrant to claim a top-three position with even a modest filing campaign. The risk is that any single actor could rapidly consolidate this space by filing a targeted claim portfolio.
Highly concentratedNo co-applicant relationships detected in current evidence
No collaboration pairs are present in the evidence. Each active applicant — Plug P2P Inc, Mercedes-Benz Research & Development North America, David Albert Sirieix, and Winnebago Industries — has filed independently. The absence of joint filings may reflect the field’s early stage, where participants are staking individual positions before potential partnerships emerge. Monitoring for future joint filings could signal alliance formation.
No co-filing detectedUS jurisdiction overwhelmingly visible; PCT coverage minimal
Five of the six jurisdictional filings are in the United States, with a single WIPO PCT application. This narrow geographic footprint means protection in key RV markets outside North America — particularly Europe and Australia — is largely unclaimed. An entrant targeting international markets could build a defensible position with relatively little direct competition from existing rights-holders.

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.
Plug P2P Inc
Plug P2P Inc holds 2 patent families, co-leading the corpus. Its technology emphasis is concentrated in B60L 53 and B60L 58 (electric vehicle charging and energy management), consistent with a peer-to-peer charging infrastructure approach. The applicant momentum trend is classified as a new entrant, indicating recent market entry rather than a long-standing position.
families: 2Mercedes-Benz Research & Development North America
Mercedes-Benz Research & Development North America also holds 2 patent families and is the only applicant with coverage spanning B60K (vehicle propulsion & drive) in addition to B60L 53 and B60L 58, reflecting a vehicle-integration angle alongside charging. The parent entity, Mercedes-Benz Group AG, appears in the route matrix with this same technical focus, suggesting coordinated IP strategy across the group.
families: 2Frequently asked questions
The corpus contains 6 patent families in scope. This is a very small body of prior art, indicating the field is nascent and has not yet attracted broad industry participation.
Plug P2P Inc and Mercedes-Benz Research & Development North America each hold 2 patent families, placing them jointly at the top of the applicant ranking. David Albert Sirieix and Winnebago Industries each hold 1 family.
The United States accounts for 5 of the 6 jurisdictional filings, with 1 WIPO PCT application. No direct filings in Europe, Asia, or other major markets are present in the evidence, leaving those jurisdictions largely open.
The field is classified as Growth. Annual filings are still rising, with a 50% recent-window growth rate, though the corpus remains very small. The most recent filing years are likely under-counted due to publication lag.
B60L (Electric vehicle propulsion) is the visible branch, covering all 6 patent records. H02J (Power supply & grid systems) appears in 3 records and B60K (Vehicle propulsion & drive) in 2. H01B (Cables, conductors & insulators) is the least-covered branch, with only 1 record and an 8% share.
No co-applicant relationships are detected in the current evidence. All four active applicants have filed independently, which is consistent with the field’s early stage where participants are establishing individual IP positions.
