Open the CIPO recordAbstract From the Canadian patent
Described herein is an implementation that produces a new representation of a digital good (such as an image) in a new defined representation domain. In particular the representations in this new domain are based upon matrix invariances. In some implementations the matrix invariances may, for example heavily use singular value decomposition (SVD).

Why it's free to use
- Filed November 8, 2004 and granted May 21, 2013. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended November 8, 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.
