Open the CIPO recordAbstract From the Canadian patent
Serving cell codes, such as group color codes are automatically assigned to serving, cells in a cellular communications network. For serving cells which share a frequency the, serving cell codes generally indicate distance from an arbitrarily chosen initial serving cell. When a new serving cell is added only serving cells sharing the channel group associated with the new serving cell need be considered and the serving cell codes for the remainder of the serving cells are unchanged.

Why it's free to use
- Filed January 15, 1998 and granted September 16, 2003. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended January 15, 2018.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by January 15, 2020.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
