Canadian Patents Database

Disclaimer

The data in the Canadian Patent Database contains bibliographic, text, and image data for Canadian patent documents filed or granted from 1920 to present. This database does not provide the full legal status of the patent documents, is not necessarily completely current, and could be missing some data. A "grace period" practice to allow mail to go through the system can delay information for at least six weeks and affect administrative status and maintenance fee information.

This database is for information purposes only. For legal purposes, it is recommended that the relevant documents in the Patent Office be consulted. Business decisions should not be made based on this search alone.

Conditions of Use

The Canadian Patents Database is intended for use by the general public. Due to limitations of equipment and bandwidth, it is not intended to be a source for bulk downloads of Canadian patents data. Bulk data may be purchased from CIPO by contacting the Client Service Centre.

Clients who, in effect, deny service to the general public by generating unusually high numbers (1000 or more) of daily dababase accesses may be denied access to the Canadian Patents Database server without further notice.

The Canadian Patents Database has been developed by CIPO to provide users with extensive information on Canadian patent documents from 1920 to the present.

You should note that the data are not necessarily complete and may not be up-to-date. They should be used for personal research and information purposes and should not be relied upon to make Business Decisions. For legal purposes, it is recommended that the relevant documents in the Patent Office be consulted.

You should also note that CIPO does not collect information about search entries or results obtained by individual users of the site.

This site has net links to other sites over which CIPO has no control and CIPO is not responsible for the accuracy, timeliness or completeness of any data on any of those sites.

CIPO is not liable to users for any damages of any kind relating to use of this site or information collected from this site or linked sites, including, but not limited -to, indirect, special or consequential damages (including lost profits or savings).
