Electric Propulsion Power Processing Units Patents: Leaders & Trends 2026
Electric Propulsion Power Processing Units: Where Patent Claims Concentrate
47.3% sits with five filers. The top five assignees account for 114 of the 241 records in scope, and the top ten hold 59.8% — concentration is heavy at the very top but not a monopoly. Filings rose from 2 records in 2017 to a peak of 23 in 2023, then eased to 10 by 2024 — a -38% move from the 2021 level of 16. Readers should not treat 2025-2026 figures as confirming a further decline; they are still filling in under the publication lag.

Common questions about this patent landscape
Who holds the most patents on electric propulsion power processing units?
One assignee leads with 57 of the 241 records in scope, well ahead of the fifth-ranked holder at 8 records. The ranking covers 84 companies in total, so while the top of the field is concentrated, the majority of ranked filers hold only a handful of records each. Anyone assessing competitive position should look at both the leader’s portfolio and the mid-field cluster around fifth to tenth place, since that group is closely spaced and could shift with a small number of new filings.
Is patent filing activity in this field growing or slowing down?
Filing activity peaked at 23 records in 2023 and then declined to 10 records in 2024, a -38% move from the 2021 level of 16 records. That 2024 figure is the most recent year with reasonably complete publication data. Because publication lags filing by roughly 18 months, the lower counts for 2025 and 2026 in any chart should not be read as continued decline — they are still filling in.
What technology areas overlap most with power processing units in this dataset?
The dataset shows heavy overlap between power electronics and discharge or materials physics rather than a single dominant subclass. C01B (non-metallic elements and inorganic compounds) covers 19.9% of the 241 records, H02S (photovoltaic and solar power) covers 18.3%, and H02J (power supply and grid systems) and H05H (plasma and particle accelerators) each cover 17.8%. Because records can carry multiple IPC codes, these shares add up to more than 100%, which reflects genuine technical overlap across converter, materials and plasma 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 Electric Propulsion Power Processing Units covering 2015–2026, data cut-off 2026-07-31.
