The link claim directs the first and second lighting control subnets to wait for a lighting control command which is transmitted to the lighting control command to the first lighting-control subnet. A random wait time is assigned to the first lighting control subnet and a maximum random wait time is assigned to the second lighting control subnet. Finally an acknowledgement is received from the first lighting control subnet.

Why it's free to use
- Filed June 9, 2004 and granted April 1, 2014. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended June 9, 2024.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 9, 2026.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
