EV Battery Pack for Micromobility Patent Landscape 2026
This is a nascent, highly concentrated field: 13 patent families in scope, with the top five filers collectively accounting for the entirety of the hundred largest filers’ combined total, and the University of Toronto holding a commanding lead. The field is still expanding on a multi-year basis, though annual volume has eased from its 2018 peak, and activity is anchored in North America with fast-charging and electric-vehicle propulsion as the dominant technology routes.
University of Toronto leads a tightly concentrated, early-stage field
The University of Toronto is the clear leader, followed by EleapPower Ltd and Havelaar Canada Industrial R&D Lab Ltd. The top five filers account for all of the activity among the ranked applicants visible in this query, signalling that this niche has not yet attracted broad industrial participation.
The tier gap between the leader and the rest is pronounced: the University of Toronto holds a substantial lead over the second-ranked applicant, with the third through fifth ranked filers each holding only a handful of patent records. This structure is characteristic of a research-institution-driven early market rather than a competitive industrial race.
| # | Applicant | Patent records | Share |

The leaders’ positions imply that foundational IP is being established primarily in academic and small-company settings, leaving the space open for industrial players to enter — or to build on licensed university research — before the field matures.
The most recent filing years are subject to publication lag and likely understate current activity; conclusions about very recent momentum 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 2018 filing spike, a multi-year lull, and signs of renewed interest after 2023
The annual trend and technology composition charts together reveal a field that burst into activity in 2018, went quiet through 2019–2023, and showed a modest uptick in 2024 — with the most-cited work concentrated in fast-charging and electric-vehicle propulsion.
Annual filing trend
Filing activity peaked in 2018, fell sharply through the following years, and recorded a small rebound in 2024. Years from 2023 onward are subject to publication lag and likely undercount current activity; the overall three-year recent window is still above the prior three-year window, consistent with the Growth lifecycle stage.

What the patent structure means for R&D investment decisions
The combination of a Growth lifecycle stage, extreme applicant concentration, active academic–industry collaboration, and a North America–visible filing footprint shapes where R&D effort is likely to yield differentiated IP.
Growth stage, easing from 2018 peak
The field is classified as Growth: the recent three-year filing window sits well above the prior three-year window, reflecting a 200% uplift. Annual volume has, however, eased from its 2018 peak, and the most recent years are further understated by publication lag. This places the field in an early-but-expanding phase where foundational IP is still being established and freedom-to-operate is relatively accessible.
Growth · eased from 2018 peakExtreme concentration among a handful of research and startup entities
The top five filers account for the full share among the ranked applicants visible in this query, and the leader holds a visible position versus peers. The absence of large automotive OEMs (with the partial exception of GM Global Technology Operations) suggests that major industrial players have not yet committed significant IP resources to this specific niche. Early movers who file now can establish durable positions before the field broadens.
Highly concentratedUniversity of Toronto anchors the collaboration network
The most active co-filing relationships documented in the evidence are between the University of Toronto and Havelaar Canada Industrial R&D Lab Ltd, with five jointly filed patent records, and between the University of Toronto and EleapPower Ltd, with two jointly filed records. This university–startup collaboration model is the defining ecosystem structure, suggesting that licensing or joint-development agreements with the University of Toronto represent the primary entry path for new industrial participants.
University-led ecosystemUS and Canada are visible in; India and EPO show early-stage presence
The United States leads in patent-record count, followed by Canada, Europe (EPO), and India in a tie, with one WIPO (PCT) filing. The North American concentration reflects the geographic base of the visible assignees. India’s presence, driven by Ather Energy Ltd, signals that the micromobility-specific battery market is attracting IP activity in high-growth two-wheeler markets. The modest EPO count suggests limited European protection to date.
