Open the CIPO recordAbstract From the Canadian patent
Devices on a communication bus enter a Ring Mode during which a master device assigns addresses to slave devices on the bus. In the Ring Mode, each slave device repeatedly attempts to send a first message informing the master device of the existence of that particular slave device. This mode includes a procedure for resolving collisions messages on the communication bus. After addresses have been assigned to all of the slave devices, a Master/Slave Mode commences. In this latter mode, each slave device sends messages over the communication bus only in response to a request from the master device.

Why it's free to use
- Filed November 20, 2001. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended November 20, 2021.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by November 20, 2023.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
