Module Balancing and Supercapacitor Pack Patents: Who Holds the Claims
Concentrated at the top. The top 5 assignees hold 60.2% of all 249 records in scope, and the top 10 hold 74.7% — a tight cluster over a long tail of single- and few-filing entrants. Annual filings climbed from 13 in 2017 to a peak of 63 in 2021, then fell to 10 by 2024 — an 84% decline over that three-year window. 2025 and 2026 figures are still incomplete because publication typically lags filing by around 18 months, so the recent-year dip should not be read as the technology cooling off.

Common questions on this landscape
Who are the leading patent holders in module balancing and supercapacitor pack technology?
The assignee ranking for this dataset covers 46 companies, with a single leader holding 97 of the 249 records in scope — far ahead of the fifth-place figure of 8 and tenth-place figure of 6. The top 5 assignees combined hold 60.2% of all records, and the top 10 hold 74.7%, so filing activity is heavily concentrated at the top with a long tail of smaller filers below. Anyone assessing competitive position should look closely at the leader's claim scope first, since it accounts for well over a third of the entire dataset on its own.
Is patent filing in this space still growing?
Filings peaked at 63 in 2021 and fell to 10 by 2024, an 84% decline over that span, so on the complete-year data the trend is down from its high point. However, because publication typically lags filing by around 18 months, the thinner counts in 2025 and 2026 are not yet a reliable read on current activity and should be treated as incomplete rather than as continued decline. The 2017-2021 run-up shows the technology went through a genuine filing boom before this pullback.
What technology areas dominate supercapacitor module balancing patents?
H02J, covering power supply and grid systems, appears in 47.0% of the 249 records, and B60L, covering electric vehicle propulsion, appears in 42.2% — together these describe most of the dataset's dual stationary-grid and mobile-EV application base. Battery and cell hardware (H01M, 27.3%) and capacitor hardware (H01G, 13.3%) follow behind. Because a single record can carry several IPC classes, these percentages add up to more than 100% of the record total, which is expected and reflects filings that combine circuit, hardware and control claims.
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 Module Balancing and Supercapacitor Packs covering 2015–2026, data cut-off 2026-07-31.
