Ultrasound Patent for Measuring Physiological Properties
Summary
The USPTO granted patent US12599369B2 to FUJIFILM SonoSite, Inc. for ultrasound methods and systems measuring physiological properties. The technology measures vessel-wall displacement and blood-flow velocity at two locations of the same vessel to determine pulse-wave velocity and blood pressure without requiring ECG data. The patent includes 20 claims and was filed on March 1, 2024.
What changed
The USPTO issued patent US12599369B2 to FUJIFILM SonoSite, Inc. on April 14, 2026, covering ultrasound methods and systems for measuring physiological properties. The patented technology measures vessel-wall displacement or blood-flow velocity at two locations along a vessel and calculates time shift between measurements to determine pulse-wave velocity or blood pressure without ECG assistance. The patent includes 20 claims and covers CPC classifications related to ultrasound diagnostics and blood flow measurement.
Medical device manufacturers and technology companies should monitor this patent for potential licensing opportunities or to assess freedom-to-operate for similar ultrasound-based physiological measurement technologies. Patent grants establish intellectual property rights but do not create direct compliance obligations for non-parties.

Abstract
Ultrasound methods and systems for measuring physiological properties are disclosed. The ultrasound methods and systems measure one or more characteristics of a vessel, such as vessel-wall displacement over time or blood-flow velocity over time, based on a pulse wave propagating through the vessel. In aspects, the characteristics are measured at two locations of the same vessel with a known distance between the two locations. A time shift between the measured characteristics at the two locations is calculated and used, along with the known distance, to determine one or more physiological properties, such as pulse-wave velocity or blood pressure. These physiological properties can be measured without the assistance of ECG data.
