Open the CIPO recordAbstract From the Canadian patent
A basilar membrane model is used to receive an input signal including a target signal in step I. With successive further steps the target signal is filtered from the input signal. After the filtering the target signal can be used as an input for further processing, like for example signal recognition of data compression. The target signal can also be applied to a substantially reverse method to obtain an improved or clean signal.

Why it's free to use
- Filed November 6, 2000 and granted July 19, 2011. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended November 6, 2020.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by November 6, 2022.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
