Open the CIPO recordAbstract From the Canadian patent
A method of activating electrodes in a multichannel electrode array using channel specific sampling sequences is presented. A channel specific sampling sequence is defined for each electrode the sequence having a particular , duration amplitude, and number of pulses. A weighting factor is applied to the channel specific sampling sequence. Each electrode in the multichannel electrode array is then simultaneously activated using sign-correlated pulses the sign-correlated pulses based on parameters of spatial channel interaction non-linear compression, and each electrode's weighted channel specific sampling sequence.

Why it's free to use
- Filed August 25, 2000 and granted January 15, 2013. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended August 25, 2020.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by August 25, 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.
