Wireless Power Transfer for Data Centers Patent Landscape
The wireless power transfer for data centers space is highly concentrated, with a single portfolio entity commanding an outsized share of a still-expanding but early-stage corpus. The field is in a growth phase on a multi-year basis, with annual volume easing from a 2023 spike, and nearly all activity is anchored in the United States.
One portfolio entity leads a heavily concentrated field
Strong Force EE Portfolio 2022 LLC holds the top position in this space by a wide margin, followed at a distance by Cisco Technology Inc and International Business Machine Corporation. The top five filers collectively account for 66% of the hundred largest filers’ combined total, signaling a field dominated by a small number of actors.
The gap between the leader and the next-ranked applicant is sharp: the leader’s count is four times that of the second-ranked filer. The second and third tiers are occupied by a mix of large technology companies, specialist hardware firms, and academic institutions, none of which approaches the leader’s volume.

The leader’s position is built almost entirely on AI-integrated power supply and grid management patents, suggesting that the dominant intellectual property frame is not purely hardware wireless transfer but AI-augmented power management for infrastructure. Challengers such as Cisco and Blue Inductive occupy narrower, more application-specific niches.
The most recent filing years (2024–2026) are subject to publication lag and will likely show higher final counts as applications publish; trend reads for those years 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.
A 2023 filing surge anchors multi-year growth; power supply and AI dominate the technology mix
The annual filing trend and the IPC branch composition together reveal a field that expanded sharply in 2023 and is now broadening into AI-adjacent and data-processing sub-domains beyond core power transfer hardware.
Annual filing trend
Filings were modest and uneven from 2017 through 2022, then surged in 2023 before settling back in 2024 and 2025. The three-year recent window sits well above the prior three-year window (317% growth), confirming multi-year expansion. The 2024 and 2025 bars are understated by publication lag and should not be read as a sustained retreat.

H02J (power supply and grid systems) is the dominant IPC branch by a large margin, consistent with the core wireless power transfer application. Notably, G06N (AI-based computing), H04L (digital information transmission), G05B (control and regulating systems), G06F (electric digital data processing), and G06Q (business and administrative data processing) each carry meaningful weight, reflecting the integration of intelligent control and energy management software into data center power architectures. Hardware-centric branches such as H02M (power conversion) and H01F (magnets and inductors) are comparatively sparse.

What the competitive structure means for R&D investment decisions
The combination of a highly concentrated applicant pool, a growth-phase lifecycle, and a technically broad IPC mix points to a field where early positioning is still possible in several adjacent sub-domains, but the core AI-augmented power management space is already heavily claimed.
Growth phase with volume easing from a 2023 peak
The field is classified as Growth: the recent three-year window outpaces the prior three-year window by 317%, confirming that cumulative activity is still expanding on a multi-year basis. However, annual volume has eased from its 2023 peak, and the most recent years are further understated by publication lag. New entrants should not interpret the post-2023 slowdown as saturation — the corpus remains small at 86 patent families and structural white space persists.
Growth · easing from 2023 peakSingle entity controls the dominant share; challengers are fragmented
Strong Force EE Portfolio 2022 LLC holds 36 patent families, more than four times the next-ranked filer. The top five filers account for 66% of the hundred largest filers’ combined total. This structure is typical of a field where a portfolio aggregator has moved early and broadly. Challengers — including Cisco Technology, IBM, Blue Inductive, and Infinity X1 — each hold single-digit family counts and occupy distinct technical niches rather than competing head-to-head with the leader.
High concentration · portfolio-ledAcademic co-filing is the primary collaboration mode; industry pairs are rare
The University of California Berkeley and the Trustees of Princeton University co-filed 3 patent families, making them the most active co-filing pair in this space. IBM and its Chinese affiliate co-filed 1 family, and Prodrive Technologies Innovation Services co-filed 1 family with ETH Zurich. Industry-to-industry collaboration is largely absent from the evidence, suggesting that cross-company joint development has not yet become a structural feature of this field.
Academia-led collaborationUS-centric filing with minimal international protection
The United States accounts for 71 patent records, far ahead of Europe (EPO) and WIPO (PCT) filings at 8 each. Germany, Austria, and India each register a single record. The narrow geographic spread means that outside the US, freedom-to-operate is relatively open for most of this technology’s sub-domains. Applicants targeting European or Asia-Pacific data center markets face a lower prior-art density than in the US.

Strong Force EE Portfolio leads on AI-augmented power management; Cisco focuses on vehicle and grid integration
The top two ranked filers differ sharply in their technical approach: the leader is concentrated in AI-driven power grid management, while the second-ranked filer emphasizes vehicle charging and non-electric variable control alongside power supply.
Strong Force EE Portfolio 2022 LLC
With 36 patent families, Strong Force EE Portfolio 2022 LLC is the clear leader. Its technology focus spans H02J 3 (power supply and grid systems), G06N 20, and G06N 3 (AI-based computing models), indicating a strategy of combining wireless power delivery with machine-learning-based control. Its applicant momentum is flagged as a new entrant, meaning its filing activity is concentrated in the recent window — consistent with the 2023 filing surge — rather than representing a long-standing incumbent position.
patent families: 36Cisco Technology Inc
Cisco Technology Inc holds 9 patent families and is the second-ranked filer. Its technical emphasis covers H02J 7 (battery charging within power supply systems), B60L 53 (wireless charging of electric vehicles), and G05D 1 (autonomous vehicle control), suggesting its data center relevance is partly framed through the lens of fleet and vehicle charging infrastructure connected to facility power networks. No momentum data for Cisco appears in the recent-window analysis, indicating its filings are distributed across both the prior and recent periods rather than concentrated in the latest window.

Under-served branches adjacent to the dominant power supply core
Several IPC branches appear in the corpus at moderate frequency but remain well below the dominant H02J anchor, pointing to sub-domains where prior art is sparse relative to their technical relevance to data center wireless power architectures.
H02M · Power Conversion (AC/DC etc.)
H02M covers AC/DC and DC/DC power conversion, the hardware layer that sits between a wireless power receiver and the data center load. It accounts for 20 patent records — 7% of the IPC distribution — yet is foundational to any practical wireless power delivery system. Blue Inductive GmbH and the University of California Berkeley are among the few filers active here. The sparse prior art relative to the technical necessity of power conversion suggests that applicants with converter topology or efficiency innovations could establish differentiated positions without immediately confronting the dominant portfolio entity.
Search this in Eureka →G01R · Electric & Magnetic Measurement
G01R covers measurement of electrical and magnetic quantities — directly relevant to coil alignment sensing, impedance monitoring, and real-time efficiency diagnostics in wireless power transfer links. It appears in 21 patent records but is absent from the top filers’ primary technology focus, indicating it is referenced in claims rather than forming a dedicated filing campaign. For teams working on in-situ monitoring, fault detection, or regulatory compliance instrumentation for data center wireless links, this branch represents a relatively uncrowded entry point with clear technical value.

Frequently asked questions
The evidence covers 86 patent families in scope for this topic.
Strong Force EE Portfolio 2022 LLC leads with 36 patent families, more than four times the count of the second-ranked filer, Cisco Technology Inc, which holds 9 patent families.
The field is in a Growth stage. The recent three-year filing window is 317% above the prior three-year window, confirming multi-year expansion. Annual volume peaked in 2023 and has eased since, but the most recent years are understated by publication lag, so the post-peak slowdown should not be read as saturation.
The United States is the dominant jurisdiction with 71 patent records. Europe (EPO) and WIPO (PCT) each register 8 records. Germany, Austria, and India each have a single record, indicating that geographic coverage outside the US is limited.
H02J (power supply and grid systems) is the dominant branch. It is followed by G06N (AI-based computing), H04L (digital information transmission), G05B (control and regulating systems), G06F (electric digital data processing), G06Q (business and administrative data processing), G01R (electric and magnetic measurement), and H02M (power conversion). This mix reflects both the hardware and the intelligent management layers of wireless power for data center infrastructure.
H02M (power conversion) and G01R (electric and magnetic measurement) are the most technically proximate under-served branches based on the evidence. H02M is foundational to any wireless receiver-to-load interface yet has sparse dedicated filings; G01R covers sensing and diagnostics directly applicable to coil alignment and efficiency monitoring in wireless links, and no top filer has made it a primary focus.
