Open the CIPO recordAbstract From the Canadian patent
A computer object such as text, graphics mathematical formulas, images, audio, and other data and information handled inside a computer or through a computer in industry or daily life etc. is expressed recorded, reproduced, and transmitted using color or a color numerical value. Color is used as a medium for expressing data or information taking note of the characteristics of color. This helps counter the ballooning amount of recording. Color can also be used to prepare codes.

Why it's free to use
- Filed May 24, 2000 and granted July 2, 2013. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended May 24, 2020.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by May 24, 2022.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
