More Electric Aircraft Power Architecture Patents: Who Leads and Where the Filing Has Gone
Filing has cooled hard. annual filings fell from 117 in 2021 to 34 in 2024, a 71% drop over that three-year span, in the last years the data treats as complete. Annual filings rose to a peak of 194 in 2019, then fell across the following years; the 2021-to-2024 window alone dropped from 117 to 34, a 71% decline. Because publication lags filing by about 18 months, 2025 and 2026 figures are still incomplete and should not be read as continued decline in their own right.

Common questions about this landscape
Who holds the most patents in more electric aircraft power architecture?
The ranking covers 100 assignees, and the leader holds 183 records out of 2,313 in scope, with the fifth-ranked assignee at 84 and the tenth at 46. The top five together hold 24.6% of all records and the top ten hold 36.7%, which means the majority of filing activity sits outside the most active names. A freedom-to-operate review in this field needs to look at the long tail of single- and few-filing entrants, not just the largest portfolios.
Is patent filing in this area growing or slowing down?
Filing peaked at 194 in 2019 and has declined since, with the 2021-to-2024 window alone dropping 71%, from 117 filings to 34. That is the most recent period the dataset treats as complete, because publication lags filing by roughly 18 months and later years are still filling in. The pattern is consistent with a field where foundational architecture claims were staked out earlier in the cycle.
What technology areas dominate the patent claims?
Power supply and grid systems (IPC class H02J) appear in 42.2% of the 2,313 records, and protective circuit arrangements (H02H) in 20.5%, making these the two densest claim areas. Digital processing (G06F) and electrical measurement (G01R) each exceed 14%, reflecting how much modern power architecture is claimed together with its monitoring and control software. Switches and relays (H01H), by contrast, sit at just 6.2%, a comparatively thin area given how central switching hardware is to the underlying engineering problem.
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 More Electric Aircraft Power Architecture 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.
