Intuitive Surgical Electrosurgical Generator Control Patent Granted
Summary
The USPTO granted Patent US12605197B2 to Intuitive Surgical Operations, Inc. on April 21, 2026. The patent covers an electrosurgical system with RF power delivery between electrodes, measurement circuitry for current and voltage, and processing circuitry using a proportional-integral-derivative control loop. The 17 claims address dynamic control of RF power based on measured current, voltage, calculated power, and calculated impedance.
What changed
USPTO issued Patent US12605197B2 to Intuitive Surgical Operations, Inc. on April 21, 2026. The patent protects an electrosurgical system that controls RF power between electrodes using a proportional-integral-derivative control loop, with the system capable of dynamically selecting control parameters from measured current, voltage, calculated power, and calculated impedance. Competitors developing electrosurgical generators with adaptive power control should review the 17 claims for potential freedom-to-operate implications and consider the impact on their own patent portfolios in the surgical energy device space.

Abstract
An electrosurgical system includes an RF output stage configured to impart RF power between first and second electrodes; measurement circuitry measures current and voltage imparted between the first and second electrodes; a processing circuit calculates power and impedance, based upon the measured current and the measured voltage; the processing circuitry uses a proportional-integral-derivative control loop to control RF power imparted between the electrodes, based upon a selected one of the measured current, the measured voltage, calculated power, and the calculated impedance.
