Supercapacitors for Regenerative Braking Patents: Leaders & Trends 2026
Supercapacitors for Regenerative Braking: Patent Landscape
71.8% concentration. The top 5 of 62 ranked assignees hold 102 of the 142 records in scope — a field with a dominant core rather than an open race. Annual filings rose from 2 in 2017 to a peak of 33 in 2023, then fell to 6 by 2024 — a 33% decline over the 2021-2024 span. 2025 and 2026 figures are still incomplete because publication typically lags filing by around 18 months, so the most recent two years understate real filing activity.

Common questions on this landscape
Who holds the most patents on supercapacitors for regenerative braking?
One assignee leads the ranked field with 31 of the 142 records in scope, well ahead of the fifth-placed filer at 8 records and the tenth at 4. The top 5 of 62 ranked assignees together hold 71.8% of all records, and the top 10 hold 90.1%, so filing activity is heavily concentrated rather than spread evenly. Anyone assessing freedom to operate here should start with that leading assignee’s claims before looking at the long tail.
Is patent filing in this space still growing?
Filings peaked in 2023 at 33 records and had fallen to 6 by 2024, a 33% decline over the 2021-2024 period using the last two years that can be treated as complete. Figures for 2025 and 2026 look lower still, but publication typically lags actual filing by around 18 months, so those recent years are undercounted rather than genuinely quiet. The honest read is a plateau after a 2023 peak, not a confirmed decline.
What technology areas do these patents cover?
The bulk of records classify under B60L (electric vehicle propulsion, 43.7% of the 142 records) and B60W (hybrid and joint vehicle control, 33.8%), with H02J power-supply and grid-systems claims and H01M battery claims each covering roughly a fifth of records. Capacitor-specific claims under H01G are comparatively rare at 4.2%. That distribution shows most competitive claiming is happening at the vehicle-control and power-management layer rather than in the storage device itself.
Disclaimer. This analysis is based on Patsnap Eureka data drawn from a limited snapshot of global patent records and is provided for general information and reference only. Patent data carries inherent limitations — recent filings are under-counted because of publication lag, counts may be on a record or family basis, classification and applicant-name data may contain errors or duplicates, and the underlying search query defines the scope shown — so the analysis may be incomplete or inaccurate and may not reflect the full technology landscape.
Nothing here is an exhaustive prior-art, novelty, freedom-to-operate or validity search, nor does it constitute legal, financial or professional advice, and it should not be relied upon as such. Verify independently and review with qualified patent and legal professionals before acting on it.
