Wireless Power Transfer for Residential Energy Patent Landscape
This is a small, highly concentrated corpus of 13 patent families dominated by a handful of specialized filers, with Syncells Inc holding the leading position. Filing activity was dormant for several years before a notable surge in 2024, driven almost entirely by new entrants, making this an early-stage field with open technical territory.
Syncells Inc leads a tightly held, early-stage field
Syncells Inc ranks first among all filers, and the top five applicants collectively account for sixty-nine percent of the hundred largest filers’ combined total, signaling a highly concentrated competitive structure for a field this small.
The tier gap between the leader and the rest of the ranking is steep: Syncells Inc holds four patent records while the next three ranked applicants — Voice Life Holdings Ltd, Strong Force EE Portfolio 2022 LLC, and Toyota Jidosha KK — each hold two. The remaining filers each hold one record, underscoring how few organizations have established a sustained presence.

The leaders’ positions imply early mover advantage is still available: even the top-ranked applicant holds a modest absolute count, and the 2024 activity spike was driven largely by new entrants rather than incumbents extending existing portfolios. There is no dominant integrated player that has locked up broad claim space.
Activity from 2024 onward is subject to publication lag and likely understates current filing volume; the apparent drop in 2025–2026 should not be read as a decline. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
A 2024 filing surge and a grid-systems-dominant technology mix
Two charts frame the field’s dynamics: the annual filing trend reveals a dormant period followed by a sharp 2024 uptick, while the technology composition shows H02J Power Supply and Grid Systems as the dominant class with several lower-density adjacent branches.
Annual filing trend
Filings were flat at two per year in 2017–2018, then fell to zero for four consecutive years before jumping to six records in 2024. The 2025 and 2026 counts are subject to publication lag and do not represent the true current pace of activity.

H02J Power Supply and Grid Systems is the dominant branch, reflecting the core power-delivery focus of the field. B60L Electric Vehicle Propulsion and H01M Batteries are secondary, pointing to residential-EV integration as a near-term application cluster. Several branches — including G06N AI models, H04L digital transmission, and H10K organic semiconductors — each carry only two records, marking them as under-served relative to the core.

What the structure means for R&D investment
The combination of a small corpus, high concentration, and a recent new-entrant surge indicates an early-commercial field where technical differentiation is still achievable across multiple branches.
Early-stage field with no confirmed life-cycle stage
The evidence does not return a classified life-cycle stage for this topic, consistent with a corpus of only 13 patent families and a filing history marked by multi-year dormancy followed by a single-year spike. The structural signals — new entrants dominating recent activity, low absolute counts, and open adjacent branches — all point to an emerging rather than mature field. R&D investments made now would encounter limited prior-art density.
Early stageTop five filers hold nearly seventy percent of the ranked pool
The top five applicants account for sixty-nine percent of the hundred largest filers’ combined total, and all recent momentum comes from new entrants rather than the incumbent leader extending its lead. This means concentration is high in relative terms but not yet entrenched: no single entity has built a portfolio broad enough to create a significant freedom-to-operate barrier for a well-scoped new entrant.
High concentrationOne co-filing relationship on record: Winter Martin and Magna International
The only co-applicant pairing in the evidence is between individual inventor Winter Martin and Magna International Inc, each contributing one jointly filed patent record. The absence of broader collaborative clusters suggests the field has not yet developed the cross-institutional R&D partnerships typical of more mature energy technology domains. This leaves ecosystem-building through joint development agreements as an open strategic option.
Minimal co-filingUnited States is the primary filing jurisdiction
Nine of the patent records are filed in the United States, with Europe (EPO), India, and WIPO (PCT) each accounting for two records. The US-centric profile reflects where early commercial development and regulatory engagement are concentrated. The thin PCT and EPO footprint means international coverage is largely unclaimed, presenting a prosecution strategy opportunity for any applicant seeking cross-border protection.

Syncells Inc leads on battery integration; Voice Life Holdings and Toyota bring grid and EV angles
The top two ranked applicants approach the field from distinct technical directions, and several new entrants entered in the most recent filing window with no prior history in the corpus.
Syncells Inc
Syncells Inc holds four patent records, the highest count in the corpus, with technical focus concentrated in H01M Batteries, Cells and Fuel Cells — specifically subclasses H01M10, H01M2, and H01M50. This battery-centric emphasis distinguishes it from the grid-management and vehicle-charging angles taken by other filers. No momentum trend data is available for Syncells in the evidence, indicating its filing activity predates the recent new-entrant surge.
patent records: 4Voice Life Holdings Ltd
Voice Life Holdings Ltd holds two patent records and is identified as a new entrant in the most recent filing period. Its technical focus spans H02J3 and H02J50 in Power Supply and Grid Systems alongside H04L9 in Digital Information Transmission, suggesting an approach that combines wireless grid integration with secure communications — a differentiated angle relative to the battery-focused leader. The new-entrant designation indicates this portfolio was built entirely within the recent activity window.

Frequently asked questions
The corpus contains 13 patent families in scope. This is a small corpus, which means the field is either highly specialized, early-stage, or both — and entry barriers from prior-art density are currently low.
Syncells Inc leads with four patent records, ahead of Voice Life Holdings Ltd, Strong Force EE Portfolio 2022 LLC, and Toyota Motor Corporation, each holding two records. The top five applicants account for sixty-nine percent of the hundred largest filers’ combined total.
The United States is the dominant filing jurisdiction with nine patent records. Europe (EPO), India, and WIPO (PCT) each account for two records. International coverage outside the US is sparse, leaving significant cross-border prosecution space open.
H02J Power Supply and Grid Systems is the dominant IPC branch, reflecting the core focus on residential power delivery and grid integration. Secondary branches include B60L Electric Vehicle Propulsion and H01M Batteries, pointing toward EV home-charging integration as a leading application cluster.
Yes. The applicant momentum data identifies Voice Life Holdings Ltd, Strong Force EE Portfolio 2022 LLC, WiTricity AI Tech LLC, Strong Force TP Portfolio 2022 LLC, SRM Institute of Science and Technology, and Nitu Panda all as new entrants in the most recent filing window. The 2024 surge in filings was driven almost entirely by these new arrivals.
The sparsest adjacent branches relative to the dominant H02J core are G06N Computing Based on AI Models (three records), and H01G Capacitors, H04L Digital Information Transmission, H10K Organic Semiconductors, and G06F Electric Digital Data Processing (two records each). AI-driven power management and organic semiconductor coil materials represent the most technically plausible entry points given current corpus density.
