Open the CIPO recordAbstract From the Canadian patent
Disclosed is a new heating device for an appliance such as a coffee urn. Such device has a main heating element and a spaced-apart warming element both of which, are embedded in a common casting. The device may be mounted to and removed from an appliance as a single unit and when mounted, the main heating element is closer to the liquid container than the warming element. The elements are vertically spaced from one another and each element has flattened coil portions contacting one another. Such flattened portions minimizes the height of the device. The new device also has one or more "points" for mounting auxiliary components such as a grounding wire and/or a thermostat.

Why it's free to use
- Filed June 4, 1996 and granted April 25, 2000. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended June 4, 2016.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 4, 2018.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
