Open the CIPO recordAbstract From the Canadian patent
In an address receiving mode of a paging receiver an address, codeword contained in each successive batch of a paging signal is compared with the address of the receiver to detect a match. The speed of data pulses generated by the receiving section are checked to see if it is in a prescribed speed range. If the receiver fails to detect an address match in one of the batches due to fading it continuously receives the, address codewords in successive batches rather than returning to, standby mode if the data pulse speed is determined to be in the prescribed range.

Why it's free to use
- Filed April 19, 1993 and granted April 13, 1999. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended April 19, 2013.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 19, 2015.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
