Open the CIPO recordAbstract From the Canadian patent
In a communications network used for electronic commerce a merchant server , sends to a customer terminal data on items available for purchase. The data is displayed at the customer terminal, for example using a web browser. The customer selects items to be purchased and a cumulative list of the selected items (the "shopping basket") is generated at the customer terminal automatically and independently of the merchant server. The cumulative list may be generated by a program encapsulated for example as a Javascript (Trade , Mark) function in the data downloaded from the merchant server.

Why it's free to use
- Filed April 29, 1999. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended April 29, 2019.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 29, 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.
