Open the CIPO recordAbstract From the Canadian patent
A multicarrier transceiver is provided with a sleep mode in which it idles with reduced power consumption when it is not needed to transmit or receive data. The full transmission and reception capabilities of the transceiver are quickly restored when needed without requiring the full (and time-consuming) initialization commonly needed to restore such transceivers to operation after inactivity.

Why it's free to use
- Filed January 26, 1999 and granted April 2, 2013. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended January 26, 2019.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by January 26, 2021.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
