In 1989, changes to Canadian patent law introduced a new patent numbering system. Patent applications files on or after October 1, 1989 were assigned serial numbers starting from 2,000,001. The application number is retained for the published (laid-open) application and issued patent, with the addition of kind codes A and C as shown below.
| Document | Number | Kind Code |
|---|---|---|
| Application as filed | 2,000,001 | |
| Laid-open application | 2,000,001 | A |
| Patent | 2,000,001 | C |
The table below shows the first application number in each year from 1989 through the present, based on data from the CIPO’s Canadian Patents Database.
