Wireless EV Charging for Recreational Vehicles Patent Landscape
The wireless EV charging for recreational vehicles patent corpus is small and highly concentrated, with Access Business Group International LLC holding a commanding share of a field that peaked around 2018 and has seen no recorded filings since. New entrants face a sparse but technically mature prior-art base dominated by inductive charging and power-supply systems.
Access Business Group leads a tightly concentrated field
Access Business Group International LLC sits at the top of the applicant ranking, followed by Philips IP Ventures BV in second position; several individual inventors share the remaining slots.
The top five filers account for 71% of the combined total among the ranked applicants visible in this query, indicating very high concentration with a sharp tier gap between the institutional leaders and the individual-inventor cohort below them.

The leaders’ positions reflect early-mover investment in inductive charging fundamentals, with Access Business Group in particular holding broad coverage across electric vehicle propulsion (B60L), power supply systems (H02J), and transformer/inductor design (H01F).
The most recent filing years should be treated with caution due to typical patent publication lags; absence of records in 2019 onward does not necessarily confirm complete cessation of activity. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
Filing activity peaked in 2018 and technology focus sits firmly in inductive power transfer
Two views together tell the structural story: the annual trend shows when and how quickly activity accumulated, while the technology composition reveals which IPC branches carry the most weight.
Annual filing trend
A single filing was recorded in each of 2018 and 2019, with no activity visible before or after in the evidence window. The field reached its peak around 2018 and has eased back entirely since. Note that the most recent periods are subject to publication lag and may undercount activity.

B60L (electric vehicle propulsion) and H02J (power supply and grid systems) are the visible branches, closely followed by H01F (magnets, inductors, and transformers). Measurement, navigation, transmission, and traffic-control branches each contribute only one or two records, pointing to underdeveloped supporting technology layers.

LADENDE PARKSTRUKTUR FÜR ELEKTROFAHRZEUG
Embodiments facilitate handling of charging parking interactions between electric vehicles (EVs) and parking structures having charging parking spaces. For example, a parking deck has a large number of parking spaces on multiple levels, and is accessible by one or more entrances. Some of the parking spaces in the parking deck are charging parking spaces… (excerpt from the patent abstract)

What the patent structure means for R&D investment decisions
The combination of a decline-stage lifecycle, extreme applicant concentration, and a compact but technically coherent prior-art base creates a distinctive risk-reward profile for new entrants and existing players alike.
Decline stage: annual volume has eased from the 2018 peak
The lifecycle evidence places this field in decline, with annual filings easing back from their 2018 peak and no recorded activity in subsequent years of the evidence window. The foundational inductive-charging claims were staked early, meaning new entrants must either design around existing positions or identify genuinely differentiated technical angles. The absence of recent filings may also reflect market uncertainty about the recreational-vehicle EV segment rather than a solved technology.
Lifecycle: DeclineOne institutional filer is visible in; individual inventors fill the mid-tier
The top five filers hold 71% of the combined total among the ranked applicants visible in this query, and most of the non-leader positions are occupied by individual inventors rather than competing corporations. This leaves the field with limited institutional diversity, which may indicate either that large incumbents have deprioritized the recreational-vehicle segment or that the market has not yet attracted broad corporate investment. Either reading suggests vulnerability to a well-resourced new entrant with a differentiated approach.
High concentrationAccess Business Group is the hub of all recorded co-filing activity
All five documented co-applicant pairs in the evidence involve Access Business Group International LLC paired individually with Weber Richard J, Taylor Joshua B, Stoner Jr William T, Eurich Sean T, and Baarman David W, each pair sharing two records. This hub-and-spoke collaboration pattern suggests the institutional leader has worked closely with a small team of named inventors rather than forming cross-company alliances. No inter-institutional collaboration is recorded, leaving that as an open structural gap.
Hub-and-spoke ecosystemUK and US each anchor four records; PCT and EPO routes used sparingly
The United Kingdom and the United States each account for four patent records, with two WIPO (PCT) filings and one EPO filing also on record. The parallel UK-US coverage by the leading applicant suggests a dual-home-market strategy, while limited PCT/EPO use indicates that broad multi-jurisdictional protection was not a priority. Markets outside these jurisdictions — including major EV-growth regions — are effectively uncovered by the existing corpus.

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.
Access Business Group International LLC
The top-ranked filer with 6 patent records, Access Business Group built its position on the three core branches of wireless EV charging: B60L (electric vehicle propulsion), H02J (power supply and grid systems), and H01F (magnets, inductors, and transformers), each covered with 8–9 records at the sub-class level. All recorded collaboration in the corpus flows through this entity. Applicant momentum data is not available in the evidence for the recent period.
6 patent recordsPhilips IP Ventures BV
Philips IP Ventures BV ranks second with 3 patent records. Detailed sub-class technology emphasis for Philips is not separately broken out in the current evidence, but its presence in second position within a small corpus indicates meaningful early investment in the space. Applicant momentum data for the recent window is not available in the evidence.
3 patent recordsFrequently asked questions
The corpus in scope contains 2 patent families. The small size reflects both the niche nature of the recreational-vehicle segment and the field’s decline-stage lifecycle, with peak activity recorded around 2018.
Access Business Group International LLC leads with 6 patent records, well ahead of second-ranked Philips IP Ventures BV with 3 records. The remaining filers are largely individual inventors with 2 records each.
B60L (electric vehicle propulsion) and H02J (power supply and grid systems) are the most represented branches, each with high record counts, closely followed by H01F (magnets, inductors, and transformers). These three branches reflect the core inductive power transfer technology stack.
The United Kingdom and the United States each have 4 patent records on file, followed by WIPO (PCT) with 2 and the EPO with 1. Major EV-growth markets outside these jurisdictions are not covered by the existing corpus.
All recorded co-filing activity flows through Access Business Group International LLC, which co-filed with five individual inventors — Weber Richard J, Taylor Joshua B, Stoner Jr William T, Eurich Sean T, and Baarman David W — each pairing yielding 2 shared records. No cross-institutional collaboration is recorded.
G01C (distance, navigation, and gyroscopes), G05D (control of non-electric variables), and G08G (traffic control systems) each have only 1 record in the corpus, while H04B (transmission, general) and G01R (electric and magnetic measurement) have 2 records each. These branches are sparse relative to the core inductive-charging stack and may represent areas with limited prior-art competition.
