Open the CIPO recordAbstract From the Canadian patent
An electronic postal scale measures the weight of an item in metric or in avoirdupois units at the user's, election. The scale also calculates a postal or shipping rate for the item, in accordance with a stored rate table defined in either metric or avoirdupois units. When the user selects a class of service, the scale determines whether there is a stored rate table for that class in the currently elected weight units. If not the scale, automatically changes to the other weight units and calculates a rate according to a stored table in those other units.

Why it's free to use
- Filed March 12, 1990 and granted October 31, 2000. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended March 12, 2010.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 12, 2012.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
