Canadian Patents, 1869-1894

Made in Canada: Patents of Invention and the Story of Canadian Innovation

The Library and Archives of Canada and Canadian Intellectual Property Office (CIPO) have launched a new online exhibition and database of patents granted to Canadian citizens and residents from 1869-1894. Some patents are jointly held by Canadians and U.S. residents. Foreign inventors not residing in Canada were permitted to apply for patents in the early 1870s.

The database contains ~14,000 patents that are indexed by patent number, patent holder name, filing year, city, province/state and title keyword. Scanned images of full-text documents are also included. The Canadian Patent Office issued approximately 44,000 patents during the 25 years covered by the database. Patents from 1895-1919 will be added in the future.
