Open the CIPO recordAbstract From the Canadian patent
The invention particularly concerns an identification process conferring traceability to products (PROD) made from data of origin (C D), initially collected at a source point (P_SOURCE) and including a command identification number (C) and fabrication data (D) common to these products (PROD). The process of the invention provides the formation of two parallel information flows (.PHI.1 .PHI.2) where each propagates the data of origin (C D) in time and space from the source point (P_SOURCE) and includes three tests (COMPAR_1 COMPAR_2, COMPRR_3) allowing the internal consistency and the integrity of the data of origin to be verified in the form in which they are propagated. Unique figure.

Why it's free to use
- Filed April 11, 2003 and granted August 30, 2016. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended April 11, 2023.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by April 11, 2025.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
