Open the CIPO recordAbstract From the Canadian patent
A process and apparatus for determining the location of a captured array from a larger image is described. A non-repeating sequence may be folded into a non- repeating array in which the array is unique for every neighboring window of a given size. A portion of the array of the neighboring window may be captured and a subset of extracted bits corresponding to the captured array is decoded to identify error bits. The location of the captured array is determined within the non-repeating array by further processing the decoded bits.

Why it's free to use
- Filed December 31, 2004 and granted January 29, 2013. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended December 31, 2024.
- Certificates of supplementary protection extend only drug patents, and it isn't classified as one.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
