Wireless EV Charging Patent Landscape 2026
Wireless EV Charging Patent Landscape in 2026
The wireless EV charging patent field is in a confirmed growth phase, with 121% expansion in the recent window and CHARGELOGIC LLC commanding a disproportionate lead over all challengers. Activity is concentrated in the United States and is heavily anchored in EV propulsion and power-supply systems, with meaningful white space remaining in magnetics, power conversion, and transmission components.
CHARGELOGIC LLC leads a highly concentrated field
CHARGELOGIC LLC holds 102 patent families, more than three times the next-ranked filer, CAPACTECH LTD at 27 families, establishing a structural lead that no single challenger currently matches.
The top five filers — CHARGELOGIC LLC, CAPACTECH LTD, BRUSA ELEKTRONIK AG, Austin Christopher B, and MAHLE INT GMBH — together account for 51% of the hundred largest filers’ combined total, indicating a sharply two-tier market: one dominant incumbent and a dispersed group of specialists and individual inventors.

CHARGELOGIC LLC’s position implies strong prior-art coverage of core inductive charging architectures; new entrants will need to differentiate on subsystem level — magnetics design, power conversion efficiency, or communication protocols — to avoid blocking claims.
Filings from 2025 and 2026 are likely undercounted due to standard patent-publication lag and should not be read as a slowdown. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
Annual activity is rising and propulsion-centric, with adjacent subsystems under-served
The filing trend and technology-composition charts together show a field that is growing rapidly and concentrated in system-level propulsion patents, while component-level and communication subsystems remain comparatively sparse.
Annual filing trend
Filings grew from 5 in 2017 to a reported peak of 62 in 2024, reflecting the 121% recent-window growth rate. The 2025 and 2026 bars should be treated as floor estimates given publication lag; the growth trajectory remains intact.

What the patent structure means for R&D investment
The combination of high concentration, confirmed growth, thin collaboration data, and a US-centric filing footprint creates a specific set of strategic imperatives for teams evaluating entry or expansion.
Growth stage with rising annual volume
The lifecycle evidence places this field firmly in the Growth stage. Annual filings are still rising on the evidence available, and the 121% recent-window growth rate confirms the field has not peaked. Teams entering now face an expanding prior-art frontier but also the opportunity to stake subsystem claims before the field matures.
Growth stageOne dominant filer; challengers are fragmented
CHARGELOGIC LLC’s 102-family position is more than three times the next filer. Below the top two, BRUSA ELEKTRONIK AG (22 families), Austin Christopher B (15), and MAHLE INT GMBH (15) form a thin second tier. The long tail includes numerous individual inventors and Indian engineering institutions, suggesting the field has not yet attracted broad corporate consolidation outside the top two.
Highly concentratedNo co-applicant activity detected in the corpus
The collaboration evidence is empty: no co-filing relationships were identified in this corpus. This is notable for a field that typically involves automaker-supplier-university consortia. It may reflect the early-stage or niche nature of specific filers in this dataset, or that collaboration is occurring outside formal co-applicant arrangements. Teams should monitor licensing and standards activity as a proxy.
Evidence pendingUS-centric filing with India as a notable secondary market
The United States leads all jurisdictions with 168 patent records, followed by India with 104 — a surprisingly strong secondary showing attributable to the volume of filings from Indian engineering institutions and universities visible in the applicant ranking. PCT filings number 34, and Europe (EPO) accounts for 16 records. China, despite its dominant EV market share, shows only 11 records, a gap that represents either a filing strategy risk or a white-space opportunity for applicants seeking Asian coverage.

CHARGELOGIC LLC leads; CAPACTECH LTD and BRUSA ELEKTRONIK AG are emerging challengers
Two applicants stand out for their combination of portfolio size and recent momentum: CHARGELOGIC LLC for sheer volume and breadth, and CAPACTECH LTD for entering
CHARGELOGIC LLC
CHARGELOGIC LLC holds 102 patent families — roughly 30% of the entire 345-family corpus — with technology emphasis spanning H01M (batteries and cells), B60L (EV propulsion), and H02J (power supply systems). Austin Christopher B, a related individual filer with 15 families, shows a +54% recent momentum trend, reinforcing that this entity group is actively expanding its coverage. The portfolio breadth across battery management, vehicle propulsion, and grid-interface classes suggests a system-level blocking strategy.
families: 102CAPACTECH LTD
CAPACTECH LTD enters the ranking as a new entrant with 27 patent families, focusing on B60L 53 (EV propulsion) and H02M 3 (power conversion) — a tighter, subsystem-oriented approach compared to the leader’s breadth. BRUSA ELEKTRONIK AG (22 families, also a new entrant) concentrates on B60L 53 and H02J 50 with additional coverage in H01F 38 (magnetics), making it the most magnetics-focused challenger in the top tier.

Magnetics, power conversion, and transmission are under-served relative to their technical centrality
Several IPC classes that are structurally essential to any wireless charging system are sparsely populated in this corpus, representing adjacent branches where differentiated filing could establish durable positions.
H01F · Magnets, Inductors & Transformers
With only 41 patent records and a 4% share of the classified corpus, H01F covers the coil and ferrite-core design that directly governs wireless power transfer efficiency and misalignment tolerance — both critical commercial differentiators. The sparse filing relative to the dominant B60L class suggests that most filers are claiming at the system level rather than the component level. Teams with coil geometry, shielding, or high-frequency magnetics expertise could file in this branch with relatively limited blocking prior art from the leading system-level filers.
Search this in Eureka →H02M · Power Conversion (AC/DC etc.)
H02M accounts for 40 patent records and a 4% share, yet DC-DC conversion topology and inverter efficiency are first-order determinants of charger performance and thermal management. CAPACTECH LTD is the only top-tier filer with a visible H02M emphasis (H02M 3, 12 records), leaving the conversion subsystem largely uncontested. Entrants with resonant converter or GaN/SiC switching expertise could establish claims here that would be complementary to — and potentially licensable to — the dominant system-level portfolio holders.
