Wireless Power Transfer for Telecom Infrastructure Patent Landscape
Wireless power transfer for telecom infrastructure is a small but concentrated field, with Nokia Technologies Oy holding the largest single-applicant position and the top five filers collectively dominating the largest filers’ combined total. Annual filing volume has plateaued near its 2024 peak, signalling a maturing but still contested space where new entrants continue to appear.
Nokia leads a highly concentrated field with several fast-moving challengers
Nokia Technologies Oy holds the top position in this landscape with 7 patent records, followed closely by eLeapPower Ltd (6), Prodrive Tech Innovation Services BV (5), Provenance Asset Group LLC (5), and Hyundai Mobis Co Ltd (5). The five largest filers together account for 58% of the hundred largest filers’ combined total, confirming a strongly concentrated competitive structure.
The gap between Nokia Technologies Oy at the top and the second-tier applicants is narrow — one or two patent records — which means the lead is contestable. Below rank five, filing volumes drop sharply to three records or fewer, creating a clear two-tier structure.

Nokia’s position, reinforced by the separately listed Nokia Corp entry, suggests a deliberate portfolio-building strategy. At the same time, the presence of automotive-sector players (Hyundai Mobis) and power-electronics specialists (Prodrive Tech, eLeapPower) signals that the competitive boundary is broadening beyond pure telecom incumbents.
Patent records filed in the most recent 18–24 months are subject to publication lag and are likely under-counted; conclusions about the very latest entrants should be treated as provisional. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
Activity plateaued near its 2024 peak; power-supply IPC classes dominate the technology mix
The filing trend and technology composition charts together show a field that has reached volume maturity while remaining technically diverse across power-supply, power-conversion, and communications branches.
Annual filing trend
Filings were negligible through 2018, then rose irregularly from 2019 onward with a pronounced spike in 2021 (8 records) and again in 2024 (9 records). The 2025 and 2026 figures should be read cautiously given publication lag — apparent softness in the most recent periods does not necessarily reflect a real decline. Overall, annual volume has plateaued near the 2024 peak.

What the portfolio structure means for R&D investment decisions
Four structural features — life-cycle stage, competitive concentration, inter-institutional collaboration, and jurisdictional geography — define the risk and opportunity profile for new entrants and incumbents alike.
Field is at a maturity plateau, not in decline
The lifecycle evidence indicates annual filings have plateaued near their peak, placing this field in a Maturity stage. This means core power-delivery and converter architectures are likely well-covered, raising freedom-to-operate risk for late entrants pursuing the dominant H02J and H02M routes. However, the irregular multi-year filing cadence suggests the field has not yet calcified — adjacent technical approaches may still be open.
MaturityTop five control 58% of the largest-filer pool; lead is narrow and contestable
The top five filers — Nokia Technologies Oy, eLeapPower Ltd, Prodrive Tech Innovation Services BV, Provenance Asset Group LLC, and Hyundai Mobis Co Ltd — together hold 58% of the hundred largest filers’ combined total. Because the gap between ranks one and five is only two patent records, a focused filing campaign by any challenger could rapidly shift the ranking. Provenance Asset Group LLC and RPX Corp as patent-assertion entities also suggest a secondary market for portfolio monetisation.
ConcentrationAcademic co-filing between UC Berkeley and Princeton is the most active collaborative link
The most active co-filing relationship identified is between the University of California, Berkeley and the Trustees of Princeton University, with 3 joint records — the strongest inter-institutional collaboration in this corpus. A secondary link exists between inventor Vuori Mikko and Nokia Corp (Finland) with 1 joint record. The absence of industry-to-industry co-filing suggests that cross-sector partnerships remain largely unexploited in this space.
CollaborationUnited States is the dominant filing jurisdiction by a wide margin
The United States accounts for 26 patent records, far ahead of EPO filings (8 records) and PCT applications (6 records). The United Kingdom (2), Israel (2), and a handful of other national offices each account for one or two records. This US-centric profile reflects where most leading applicants are incorporated or seek primary protection, but the thin EPO and PCT coverage may represent gaps exploitable by applicants seeking broader territorial rights.

Nokia focuses on power supply and transmission; eLeapPower enters aggressively via EV-adjacent wireless charging
The two largest filers approach wireless power transfer from distinct technical directions — Nokia from a telecom-native power-management angle, and eLeapPower from a power-delivery and EV-charging convergence angle — suggesting limited direct overlap and coexisting competitive lanes.
Nokia Technologies Oy
Nokia Technologies Oy leads with 7 patent records, concentrated in H02J 7 (power supply and grid systems, 9 sub-records), H04B 5 (transmission, 4 sub-records), and H01F 38 (magnets and inductors, 2 sub-records). This profile reflects a telecom-native framing of wireless power — coupling energy delivery tightly with transmission and magnetics. Momentum data for Nokia Technologies Oy specifically is not included in the recent-entrant tracking, indicating an established rather than newly emerging position.
patent records: 7eLeapPower Ltd
eLeapPower Ltd holds 6 patent records and is flagged as a new entrant, with all 6 records filed in the most recent tracked period. Its technical focus spans B60L 53 (EV propulsion, 6 sub-records), H02J 50 (wireless power supply, 6 sub-records), and H02J 7 (power management, 6 sub-records), pointing to a strategy that bridges EV charging infrastructure and telecom power delivery. The rapid ramp from zero to 6 records in a short window warrants close monitoring.

Under-served IPC branches adjacent to the dominant power-supply core
Several IPC branches appear at the periphery of this corpus with low patent-record counts relative to the dominant H02J cluster. Two in particular combine technical relevance to telecom wireless power with plausible entry paths for differentiated portfolios.
H04W · Wireless communication networks
H04W accounts for only 7 patent records in this corpus — sparse relative to the 38 records in H02J. Given that wireless power transfer for telecom infrastructure inherently involves network-layer coordination (beam scheduling, handoff, load balancing across base stations), the thin H04W coverage suggests that the communication-protocol aspects of wireless power delivery remain largely unaddressed. A team with combined RF and power-electronics expertise could pursue filings targeting network-managed power routing without directly colliding with the dominant H02J incumbents.
Search this in Eureka →H01F · Magnets, inductors & transformers
H01F holds only 6 patent records, despite inductive coupling being the dominant physical mechanism in near-field wireless power transfer. Coil geometry, core material selection, and transformer design optimised for telecom enclosure form factors (compact, thermally constrained) represent a hardware differentiation path. The sparse H01F coverage implies that component-level magnetics innovation specific to telecom infrastructure power delivery is an under-served adjacent branch worth monitoring, particularly for component manufacturers or materials specialists seeking a foothold.

Frequently asked questions
The corpus in scope contains 28 patent families. This is a relatively small and specialised field compared with broader wireless power transfer or general telecom patent landscapes, reflecting the niche intersection of high-frequency power delivery and telecommunications infrastructure requirements.
Nokia Technologies Oy leads with 7 patent records, followed by eLeapPower Ltd (6), Prodrive Tech Innovation Services BV (5), Provenance Asset Group LLC (5), and Hyundai Mobis Co Ltd (5). Nokia Corp appears separately in the ranking with 1 additional record, suggesting a combined Nokia-family portfolio larger than any single entry shows.
The evidence indicates a Maturity stage: annual filings have plateaued near their 2024 peak. This suggests that foundational power-supply and converter approaches are becoming well-covered, while adjacent branches in wireless network coordination and magnetics component design remain comparatively open.
The United States is by far the primary filing jurisdiction with 26 patent records. Europe (EPO) follows with 8 records, and WIPO (PCT) accounts for 6. A small number of national filings exist in the United Kingdom, Israel, Canada, China, Germany, India, and South Africa. The strong US-centricity suggests that applicants seeking broader territorial coverage through EPO or PCT routes may encounter less crowding.
The most active collaboration identified is between the University of California, Berkeley and the Trustees of Princeton University, with 3 jointly filed patent records. A secondary link between inventor Vuori Mikko and Nokia Corp (Finland) accounts for 1 joint record. Industry-to-industry co-filing is not evidenced in this corpus, indicating that cross-sector R&D partnerships have not yet translated into joint patent activity in this specific field.
H04W (Wireless communication networks, 7 records) and H01F (Magnets, inductors and transformers, 6 records) are the most technically relevant under-served branches relative to the dominant H02J class (38 records). G06Q (Business and commerce data processing, 5 records) and G06F (Digital data processing, 1 record) are also sparse, though their direct technical relevance to core wireless power delivery is less immediate.
