High-Voltage Equipment Patents: Top Companies & Filing Trends 2026
High-Voltage Equipment Patents: Who Leads and Where Filings Are Heading
Concentrated at the top. the five most active filers account for 31.6% of all 1,422 records in scope, and the top ten hold 41.6% — filing is real but not locked up by a single entrant. Filings peaked in 2017 at 62 and declined to 18 by 2024, a 50% drop across that three-year stretch. Because publication typically lags filing by around 18 months, the 2025–2026 figures (down to 4 in 2026) are still incomplete and should not be read as a continued fall.

Common questions on high-voltage equipment patents
Who holds the most high-voltage equipment patents?
One assignee leads the ranked field with 202 records, well ahead of the fifth-place holder at 44. The top five combined hold 31.6% of all 1,422 records in scope, and the top ten hold 41.6%, so while there is a clear leader, the majority of filings are spread across a long tail of smaller and single-filing entrants. Checking that tail matters as much as watching the leader when assessing competitive risk in a specific sub-branch.
Is high-voltage equipment patent filing growing or slowing?
Filing peaked in 2017 at 62 records and has declined since, falling from 36 in 2021 to 18 in 2024 — a 50% drop over that three-year span. The 2025 and 2026 figures look lower still, but publication typically lags filing by around 18 months, so those most recent years are understated and should not be read as continued decline yet. The safest read is that filing activity has cooled meaningfully from its 2017 peak through 2024.
What technology areas dominate high-voltage equipment patents?
Switches and relays (IPC class H01H) and power supply and grid systems (H02J) are the two largest categories, each covering roughly a quarter of the 1,422 records in scope. Measurement circuits (G01R) and protective circuit arrangements (H02H) follow closely at 16.8% each, and photovoltaic integration (H02S) and semiconductor devices (H01L) make up smaller but still substantial shares. Because many filings carry multiple IPC codes, these categories overlap rather than partition the field, which reflects how often switching, sensing and protection claims are bundled together.
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.
