Open the CIPO recordAbstract From the Canadian patent
Trays within a given level of a drum-type vending machine form individual zones, and may be further subdivided into additional individual zones for which, pricing may be separately specified. A vend door for the corresponding level is constrained to allow access to a given zone upon payment of the appropriate amount. More levels and greater flexibility in pricing and product selection are thus enabled, together with greater control over vending operations.

Why it's free to use

- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by October 15, 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.
