A character recognition system and method that are useful for reading automatically characters marked on tags. The user defines the symbols that will be assigned to each character pattern generated by the system for each character marked on the tag. The symbols that are assigned to each character can be modified easily by the user. Thus, the system permits quick adaptation to new or changing character styles or patterns.

Why it's free to use
- Filed September 17, 1990. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended September 17, 2010.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by September 17, 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.
