Open the CIPO recordAbstract From the Canadian patent
An informative card, such as a baseball trading card, has a rectangular shape and is made of a single thin sheet of metal in such a way that it is free of pointed corners or exposed raw edges. The informative card has four rounded corners and a double-thickness frame defined by a folded lip which has four straight edges and four rounded connectors joining the straight edges at the corners. The folded lip provides an unbroken radiused peripheral edge bordering the card. A central display panel of the card is offset rearwardly to form a raised ledge on the front side of the card surrounding the central display panel.

Why it's free to use
- Filed April 1, 1997 and granted June 13, 2000. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended April 1, 2017.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 1, 2019.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
