Traction Inverter for Micromobility Patent Landscape
The traction inverter for micromobility patent space is extremely concentrated, with three applicants accounting for the entire ranked corpus and the University of Toronto holding the largest single position. The field is in a growth stage on a multi-year basis, though annual volume has eased from its 2018 peak and recent years remain understated by publication lag.
Three applicants dominate a nascent, highly concentrated field
The University of Toronto (via its Governing Council) leads the ranking, followed by EleapPower Ltd and Havelaar Canada Industrial R&D Lab Ltd — together these three organizations account for the entire top-100 ranked pool.
With the top five filers holding one hundred percent of the hundred largest filers’ combined total, the concentration level is exceptional even by early-stage field standards, signalling that this technology niche has not yet attracted broad industry participation.
| # | Applicant | Patent records | Share |
|---|---|---|---|
| 1 | The Governing Council of the University of Toronto | 21 | |
| 2 | EleapPower Ltd | 18 | |
| 3 | HAVELAAR CANADA IND R & D LAB LTD | 3 |
The leaders’ positions are rooted in academic-industry collaboration rather than large-scale corporate programs, which suggests the IP landscape remains open to new entrants with product-oriented claims.
The most recent approximately 18–24 months of filings are subject to publication lag and are likely under-counted; apparent zero-filing years in 2023–2026 should not be read as cessation of activity. Longer-window growth, applicant concentration, and technology-route coverage are therefore more reliable signals than the latest-year bar alone.
A 2018 burst followed by intermittent activity, with power-electronics branches dominating
The filing timeline reveals a pronounced early spike and a technology composition anchored in electric-vehicle propulsion and power conversion, with several adjacent branches pointing to cross-sector applications.
Annual filing trend
A single large burst in 2018 (13 patent records) defines the historical pattern; subsequent years show sparse, intermittent filings. The field’s growth-stage classification reflects a positive recent three-year window versus the prior three-year window, not continuous annual expansion. Years from 2023 onward are further understated by publication lag and should not be interpreted as inactivity.

B60L (Electric vehicle propulsion) and H02J (Power supply and grid systems) are the two heaviest branches, closely followed by H02M (Power conversion). Smaller counts in B63B, B63H, and B64D indicate that some families extend inverter concepts into marine and aerospace contexts, while H02H (Protective circuit arrangements) represents a modest but technically important safety sub-theme.

What the structure means for R&D investment decisions
The combination of high concentration, university-led IP, and a sparse annual rhythm creates specific strategic implications for engineers considering entry or portfolio expansion.
Growth stage — multi-year expansion, annual volume eased from 2018 peak
The field is classified as Growth because the recent three-year filing window sits above the prior three-year window by 33 percent. However, annual volume has eased from its 2018 peak and the most recent years are further understated by publication lag. An R&D team entering now would be moving into a still-forming, not yet saturated, IP space.
Growth StageExtreme concentration — three assignees, no large-corporate presence
The top five filers hold the entire share of the hundred largest filers’ combined total, and the three known assignees are two Canadian companies and one Canadian university. No established power-electronics or automotive-tier OEM appears in the ranked corpus, leaving wide room for industrial actors to stake claims in application-specific inverter architectures.
High ConcentrationUniversity–industry co-filing is the dominant IP-generation model
The University of Toronto (Governing Council) co-filed with Havelaar Canada Industrial R&D Lab Ltd in 12 patent records and with EleapPower Ltd in 4 patent records — together these two pairings represent the main collaborative activity in this space. This pattern suggests that licensing arrangements or joint-development agreements with the University of Toronto may be a faster route to IP access than independent prosecution.
Collaborative IPUS leads filings; Canada, Europe, and India also covered
The United States is the lead jurisdiction, followed by Europe (EPO), Canada, India, and WIPO (PCT). The PCT route remains lightly used, meaning international coverage outside North America and Europe is thin. India’s presence is notable given its large and growing micromobility market, but the overall geographic footprint of this corpus is still narrow.

Co-filing pairs, ranked by the number of jointly-filed patent families.
University of Toronto leads; EleapPower is the closest industrial challenger
All three ranked applicants are Canadian entities, and two are showing new-entrant momentum in the most recent measurement window, indicating that activity has not fully ceased despite irregular annual filings.
University of Toronto (Governing Council)
Holding 21 patent records, the University of Toronto is the clear corpus leader with a technology focus on H02J 7 (power supply and grid systems, 18 records), B60L 15 (electric vehicle propulsion, 12 records), and B60S 5 (vehicle servicing, 11 records). Its momentum trend is flagged as a new entrant in the recent window, consistent with intermittent prosecution activity rather than a sustained corporate filing program.
patent records: 21EleapPower Ltd
EleapPower Ltd holds 18 patent records and concentrates its filings in B60L 53 (electric vehicle charging/propulsion, 4 records), H02J 7 (power supply, 4 records), and B60L 15 (propulsion control, 2 records). Its momentum is also flagged as a new entrant in the recent window. Its four co-filings with the University of Toronto suggest an active technology-transfer relationship.

Marine and aerospace extensions are under-served relative to the EV core
Several IPC branches in the corpus sit well below the dominant propulsion and power-conversion classes, flagging areas where the existing IP is sparse and where technically adjacent applications of micromobility-scale inverters may have limited coverage.
B63B / B63H · Marine micro-vessel propulsion
B63B (Ships and marine vessels) and B63H (Marine propulsion and steering) each carry small counts in this corpus, indicating that inverter architectures developed for electric micromobility have been partially extended to small marine craft but not yet deeply claimed. For engineers working on electric personal watercraft or small-boat drives, this branch represents a sparse adjacent zone where the entry barrier from a freedom-to-operate standpoint appears low, given the thin existing coverage.
Search this in Eureka →H02H · Protective circuit arrangements for compact inverters
H02H (Protective circuit arrangements) appears with only 4 patent records in this corpus, despite fault protection being a critical reliability requirement in micromobility inverters operating in uncontrolled environments. This relative sparsity suggests that safety and protection topologies specifically adapted to compact, low-voltage traction inverters are an under-claimed sub-theme. A technically grounded filing program in H02H could complement existing B60L and H02M positions without directly competing with the corpus leaders.
