A method for interactively correcting text and providing user guidance includes monitoring user input to identify predefined events. In response to identifying predefined events the predefined events in a rule-base are scheduled for evaluation. Evaluation of events causes dependent events and rules to be scheduled. Evaluation of a rule includes determining whether the conditions for the rule are satisfied and if so, scheduling further events or rules dependent on the rule or triggering actions to automatically correct text or display helpful tips to the user.c

Why it's free to use
- Filed May 31, 1996 and granted March 19, 2002. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended May 31, 2016.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by May 31, 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.
