It's now easier to find the documents you are looking for on the Canadian Patent Database.
The Canadian Patent Database now allows you to filter through patent and application documents according to three specific points in time:
- At the time of filing
- At the time the application was opened to public inspection
- At the time of issuance
CIPO's Canadian Patent Database lets you access 147 years of patent descriptions and images. You can search, retrieve and study more than 2,260,000 patent documents.
