Open the CIPO recordAbstract From the Canadian patent
A thermostat providing external communication comprising two microprocessors. One microprocessor may be dedicated to the external communication while the other microprocessor runs the application programming. The thermostat is separated into a thermostat housing and subbase. One microprocessor may be located within the thermostat housing with the other located within the subbase. This allows for changing the applications programming through replacement either the housing or the subbase. Replacement of only one portion of the thermostat is cheaper and can be easier.

Why it's free to use
- Filed December 18, 1992. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended December 18, 2012.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by December 18, 2014.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
