Inverters and Converters Patents: Filing Trends and the Competitive Field
Filings peaked in 2021 at 1,147 and fell 36% to 737 by 2024, the last year the data can treat as complete. Annual filings climbed from 1,070 in 2017 to a peak of 1,147 in 2021, then fell to 737 by 2024, a 36% decline over that three-year span. 2025 and 2026 figures in the underlying data are still filling in, since publication typically lags filing by around 18 months, so the apparent drop-off in the very latest years should not be read as the field's current trajectory.

Common questions about the inverters and converters patent landscape
Who holds the most patents in inverters and converters?
The ranked leader in this dataset holds 1,150 records, well ahead of the fifth-ranked assignee at 939 and the tenth at 615. Even so, the top 10 combined account for only 18.6% of all 47,812 records in scope, so no single company controls a dominant share of the field. This means freedom-to-operate work needs to look well beyond the first few names, since a large majority of filings sit with assignees outside the top ranks.
Is inverter and converter patent filing activity growing or shrinking?
Filings rose from 1,070 in 2017 to a peak of 1,147 in 2021, then declined to 737 by 2024, a 36% drop over that three-year span. Figures for 2025 and beyond are still incomplete because publication typically lags actual filing by around 18 months, so the most recent years understate real activity rather than proving a continued decline. Anyone using this trend to time a filing decision should treat 2024 as the last reliably complete data point.
Which patent classification covers the most inverter and converter filings?
H02M, the power-conversion subclass covering AC/DC and related circuits, appears in 27.0% of all 47,812 records, far ahead of any other class. The next largest, H02J for power supply and grid systems, holds 7.1%, and several supporting classes covering motor control, pulse logic, measurement and semiconductor devices each sit between 2.0% and 3.5%. Because a single record can carry multiple classes, these shares add up to more than 100% and should not be summed 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.
Method: Filing trend and technology composition. Derived from a Patsnap search on Inverters & Converters Patent Landscape covering 2015–2026, data cut-off 2026-08-31.
