Open the CIPO recordAbstract From the Canadian patent
The software error handling determines the nature of the fault and takes different action depending upon the nature of the fault. If the fault prevents the data processing system from continued reliable operation, then the element causing the fault is immediately disabled. Otherwise the element, which is the source of the fault is treated so that it does no harm to the system and causes no further faults. The element can then be completely handled during normal software status checks.

Why it's free to use
- Filed July 30, 1990. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended July 30, 2010.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by July 30, 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.
