Regenerative Braking Patents: Top Companies & Filing Trends 2026
Regenerative and Electrodynamic Braking Patents: Who Leads and Where Filing Is Heading
Filing nearly quadrupled in three years. 2021 to 2024 filings rose from 28 to 102 records, a +264% jump, before the two most recent years understate activity due to publication lag. Filings climbed from 39 in 2017 to a peak of 102 in 2024, with 2021's 28 to 2024's 102 marking a +264% run. The 2025 and 2026 figures (down to 15 in the partial latest year) should be read as incomplete rather than as a slowdown, since publication typically lags filing by around 18 months.

Common questions on this landscape
Who holds the most patents in regenerative and electrodynamic braking?
The dataset ranks 100 assignees across 841 records, with the leading company alone accounting for 181 records. The five leading assignees together hold 45.3% of all 841 records in scope, and the leading ten hold 57.4%. That said, the ranking is not a top-50 or top-100 industry list — it is the complete set the data endpoint returns, and over 40% of filings sit outside the ten leaders, spread across a long tail of smaller filers.
Is patent filing in this field growing or slowing down?
Filings grew sharply between 2021 and 2024, from 28 to 102 records, a +264% increase. The apparent drop-off after 2024, down to 15 in the most recent partial year, is best read as a publication-lag effect rather than a genuine slowdown, since patent publication typically trails filing by around 18 months. Treat 2024 as the most recent year with a reasonably complete picture.
What technology areas dominate regenerative braking patent claims?
B60L, the IPC subclass covering electric vehicle propulsion, appears in 46.7% of the 841 records in scope, making it the single largest technology cluster. H01M (batteries and cells) follows at 24.4%, and H02M (power conversion) at 14.6%. Notably, B60T, the subclass for vehicle brakes specifically, appears in only 12.5% of records, indicating that most of the inventive activity is happening in the electrical and control systems around the brake rather than in brake hardware 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.
Method: Filing trend and technology composition. Derived from a Patsnap search on Regenerative and Electrodynamic Braking covering 2015–2026, data cut-off 2026-07-31. Counts reflect published records only and shift as new filings publish. Every share divides by all records in scope. Data: Patsnap Eureka. See the full landscape report.
