Open the CIPO recordAbstract From the Canadian patent
A system for high speed acquisition and decoding of a barcode symbol locates potential barcode candidates within a scanned image and filters the candidates to eliminate invalid data. The system permits computational resources to be focused on decoding information most likely to be an actual barcode symbol. Once a potential barcode candidate has been located, the barcode symbol is processed to determine the barcode orientation and symbology. Each element of the barcode symbol is then located, even if all elements are not visible in the original image, and the barcode symbol is decoded in accordance with the specific symbology.

Why it's free to use
- Filed June 3, 1997 and granted January 22, 2002. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended June 3, 2017.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 3, 2019.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
