Canadian Intellectual Property Office (CIPO)

The Canadian Intellectual Property Office (CIPO) Patent PostgreSQL Database is a metadata extract from CIPO's IP Horizon's XML Databank that contains information on almost 2.5 million patent documents filed in Canada. Data are available from 1870 to present, and include metadata as well as the full text of patent descriptions and claims information. These documents represent both patent applications and patent grants, as well as patents that have expired. Many patents provide references to equivalent patents filed in other countries, via the World Intellectual Property Office's (WIPO) Patent Cooperation Treaty (PCT).
