Wireless Battery Charging Patent Landscape 2026
Wireless Battery Charging Patent Landscape in 2026
Medtronic leads a moderately concentrated field in which the top five filers account for 27% of the hundred largest filers’ combined total, with activity peaking in 2018 and annual volume having eased since. The dominant technology class is H01M (batteries and cells), and the United States is the primary filing jurisdiction, indicating a field that has matured but retains selective pockets of activity in medical and automotive adjacent branches.
Medtronic leads a moderately concentrated field shaped by medical and energy-storage specialists
Medtronic holds the top position in the applicant ranking, followed by LAT Enterprises and Robert Bosch. The top five filers together represent 27% of the hundred largest filers’ combined total, a moderate concentration level that leaves meaningful room for challengers.
A visible tier gap separates Medtronic and LAT Enterprises from the mid-tier cluster that includes Quallion, 24M Technologies, Hubbell, Apple, and Schumacher Electric, each filing at roughly one-third the volume of the top two. Below that, a long tail of single-digit or low-teens filers makes the field accessible to new entrants in adjacent niches.

The leaders’ positions reflect divergent strategies: Medtronic concentrates on implantable medical device charging, while LAT Enterprises emphasises battery-management and solar-integrated systems, and Robert Bosch spans broad power-supply infrastructure. This diversity at the top means no single player dominates the full technology stack.
The most recent 18–24 months are subject to publication lag and will be revised upward as applications publish; interpret 2025–2026 filing figures with caution. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
Filing peaked in 2018 and has plateaued; battery-cell fundamentals dominate the technology mix
The annual trend and technology composition charts together reveal a field that built momentum through 2018 and has since settled into a lower, stable band of activity, concentrated in battery-cell and power-supply classes.
Annual filing trend
Filings rose from 81 records in 2017 to a peak of 107 in 2018, then declined steadily to a plateau of around 52–59 per year from 2020 onward. The 2025 figure shows a modest uptick to 61, but given publication lag this should not yet be read as a reversal; the 2026 figure of 2 is a near-complete artefact of lag. Overall the field is past its 2018 peak on an annual basis.

H01M (batteries, cells, and fuel cells) and H02J (power supply and grid systems) together dominate the IPC composition, reflecting foundational work on cell chemistry and charging-circuit design. Third-ranked B60L (electric vehicle propulsion) is present but at a materially lower share, pointing to EV charging as a secondary rather than primary focus. Medical classes A61N and A61B together indicate a meaningful implantable-device sub-segment.

What the portfolio structure means for R&D strategy
The combination of a post-peak filing curve, moderate concentration, absence of formal co-filing networks, and a US-centric jurisdiction footprint shapes the risk-reward calculus for new entrants and incumbents alike.
Post-peak field: annual volume has eased from its 2018 high
The lifecycle evidence classifies this field as in decline, with annual filings easing back from the 2018 peak of 107 records. The multi-year corpus of 619 patent families represents a substantial prior-art base that new entrants must design around. R&D investment is most defensible in differentiated sub-domains — notably implantable medical devices and EV-adjacent inductive systems — where the prior-art density is lower.
Lifecycle: DeclineModerate top-tier concentration with a wide challenger tier
The top five filers hold 27% of the hundred largest filers’ combined total, leaving 73% distributed across a broad mid-tier and long tail. The gap between Medtronic (71 patent records) and the fifth-ranked filers at 22 records is significant, but the mid-tier cluster is dense enough that a focused portfolio of 20–30 records in a specific sub-domain could establish a credible position. Entrants with LAT Enterprises showing a recent momentum trend of +100% demonstrate that the ranking is still mobile.
Moderate concentrationNo formal co-filing activity detected in this corpus
The collaboration evidence is empty — no co-applicant pairs appear in the dataset. This absence of formal joint-development agreements or cross-institutional filings suggests that players are developing proprietary positions independently, consistent with the competitive, rather than consortium-driven, structure visible in the applicant ranking. Collaborative entry via joint ventures or licensing arrangements with mid-tier holders may therefore represent an underexplored route.
No co-filing detectedUS-centric filing with selective EPO and PCT coverage
The United States is the dominant jurisdiction at 628 patent records, far ahead of EPO at 148 and WIPO PCT at 109. Germany, Australia, and Canada form a secondary tier. China registers only 10 records despite being a major battery manufacturing base, suggesting either a deliberate filing strategy gap or that Chinese-origin filings are captured under different entities. An applicant seeking freedom-to-operate outside the US or EPO perimeter may find relatively sparse opposition in several key manufacturing jurisdictions.

Medtronic and LAT Enterprises lead from distinct technology positions
The two leading filers differ markedly in their technology emphasis and momentum trajectory, reflecting the breadth of applications that wireless battery charging spans — from implantable medical devices to battery-management and solar-integrated systems.
Medtronic Inc
Medtronic holds the top position with 71 patent records, concentrated in H01M battery-cell technology and A61N electrotherapy — a profile consistent with rechargeable implantable neuromodulation and cardiac devices. Recent momentum is classified as a new entrant trend in the latest window, suggesting the legacy portfolio is well-established but recent incremental activity is modest. The co-filing of focus across H01M 4, H01M 10, and A61N 1 confirms a tightly integrated medical-charging stack.
patent records: 71LAT Enterprises Inc
LAT Enterprises ranks second with 62 patent records and is the fastest-growing major filer at +100% in the recent window versus the prior period. Its technology emphasis spans H01M 10, H01M 50 (battery cell housings and management), and H02S 30 (photovoltaic power generation), pointing to a solar-integrated wireless charging architecture. This solar-plus-battery positioning is differentiated from the medical-device focus of the leader and may reflect an emerging industrial or outdoor-equipment application niche.

Under-served branches in EV propulsion, magnetics, and medical electrotherapy
Five branches appear in the whitespace analysis as lower-share IPC classes adjacent to the dominant H01M and H02J core. Two warrant closer attention for their combination of sparse coverage and plausible technical entry paths.
H01F · Magnets, inductors & transformers
H01F registers only 90 patent records and a 3% share of the corpus, despite inductive coil and transformer design being a fundamental enabler of wireless power transfer efficiency. The sparse coverage relative to H01M suggests that coil geometry, magnetic shielding, and ferrite-core optimisation for high-frequency wireless charging remain less contested than cell chemistry. An entrant with materials or magnetics expertise could establish a differentiated position in coil-design and near-field coupling without navigating the densely filed H01M prior-art landscape.
Search this in Eureka →A61N · Electrotherapy & radiation therapy
A61N holds 73 patent records and a 2% share, despite Medtronic and Quallion both listing A61N 1 among their top focus codes. This indicates that the incumbent medical-device leaders have filed selectively in electrotherapy-specific wireless charging but have not saturated the class. Implantable spinal cord stimulators, cochlear implants, and closed-loop neuromodulation devices all require miniaturised wireless charging with tight safety margins — sub-areas where the current record density suggests room for specialist filers, particularly those combining A61N charging protocols with H01M cell management.
