Canadian Patent Database
The Canadian Patent Database contains patent documents from 1869 to the present time. The patent information consists of patent document images, bibliographic data and patent document text. Click on (i) next to title for more information.
For patents granted prior to August 15, 1978, the text of the abstracts and claims is not available. These patents can only be searched by their patent numbers, their titles, the assignee or inventor names, or classification number.
Canadian patent applications can be filed in either English or French. All patent documents on this site have both English and French titles, but between 1960 and 1978 only the language used at the time of filing is available.
