Open the CIPO recordAbstract From the Canadian patent
A system and method for detecting and predicting neurological events with an implantable device (110) uses a relatively low-power central processing unit (428) in connection with signal processing circuitry (422) to identify features (including half waves) and calculate window-based characteristics (including line lengths and areas under the curve of the waveform) in an electrographic signal received from a patient's brain. The features and windowbased characteristics are combinable in various ways according to the invention to detect and predict neurological events in real time enabling , responsive action by the implantable device.

Why it's free to use
- Filed June 28, 2002 and granted May 20, 2014. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended June 28, 2022.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 28, 2024.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
