Electrosurgical Generator Patents: Leaders & Filing Trends 2026
Electrosurgical generator and energy control patents: who holds the ground and where it is still open
Filings peaked in 2021 at 10 then fell to 2 by 2024, an 80% drop over that three-year span — the clearest signal in this dataset that the active filing window has narrowed. Recorded filings ran from 1 in 2017 up to a peak of 10 in 2021, then declined to 2 by 2024 — an 80% fall over that three-year window. 2025 and 2026 figures are still filling in due to publication lag and should not be treated as the final word on recent activity.

Common questions on this landscape
Who are the leading patent holders in electrosurgical generator technology?
One assignee dominates this landscape with 50 patent families, well ahead of the fifth-ranked company at 4 families. The ranking covers 14 companies in total, counted by family, and the drop-off after the leader is steep rather than gradual. Anyone entering this space for freedom-to-operate purposes should treat that leading portfolio as the primary point of review, since the rest of the ranked list holds comparatively modest positions.
Is patent filing in electrosurgical generators still growing?
Filing activity peaked in 2021 at 10 records and had fallen to 2 by 2024, an 80% decline over that three-year span. That is the most recent period this dataset treats as reliably complete, since publication typically lags actual filing by around 18 months. Figures for 2025 and 2026 are still filling in, so they should not yet be read as confirmation of a continued decline.
What technology areas do electrosurgical generator patents cover?
Within this dataset, 99.1% of the 106 records fall under IPC subclass A61B, which covers diagnosis and surgery, while only 0.9% touch H02M power-conversion hardware. That split shows claim activity is concentrated on the surgical-system side — output waveform control, tissue response sensing, return electrode monitoring — rather than on the underlying generator electronics. A record can carry more than one IPC class, so these shares add up to over 100%.
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 Electrosurgical Generators and Energy Control 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.
