Open the CIPO recordAbstract From the Canadian patent
In a local stethoscope unit, acoustic auscultation sounds picked up by the stethoscope chest piece assembly of a local stethoscope unit are converted to analog electrical signals and then converted to digital signals. The digital signals are conveyed to a data communications system having data communications device and a data communication channel. The digital signals are transmitted over the digital communications system to a remote stethoscope receiving unit. The remote stethoscope unit converts the digital signals back to the original analog signals suitable for listening.

Why it's free to use
- Filed October 6, 2004 and granted December 11, 2012. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended October 6, 2024.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by October 6, 2026.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
