Open the CIPO recordAbstract From the Canadian patent
The present invention provides a system where offers are placed on network accessible sites or delivered to consumers over a network (110). Placement data is used to obtain offers that share at least one category with placements of offers for consumers. Each offer has a placement value for placement. The offers are randomized by forming randomized placement values for the placement. These randomized placement values are calculated by adding a random factor (430) ranging up to at least the value of the highest placement value to each of the offers' placement values. The offer with the highest randomized placement value is then placed for viewing or receipt, by the consumer (440).

Why it's free to use
- Filed March 13, 2003 and granted March 11, 2014. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended March 13, 2023.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 13, 2025.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
