Help: Frequently Asked Questions on the Canadian Patents Database application

What information is offered by the CIPO Canadian Patent Database?

For patent documents that are either public inspection applications or are patents granted since August 15, 1978, the CIPO Canadian Patent Database contains bibliographic data, textual data (titles, abstracts and claims) and image data.

For patents granted prior to August 15, 1978, the CIPO Canadian Patent Database contains bibliographic data, the text of titles only (no text of abstracts and claims) and image data.

I am concerned that I may reveal confidential design information with my searches. What is your policy on the management of the CIPO Canadian Patent Database access log?

The communications between CIPO Canadian Patent Database and the users of the CIPO Canadian Patent Database site are not of a confidential nature. Therefore, any communications that you wish to remain confidential, whether they are search queries, Canadian Patent Database Feedback entries, e-mail, or any other communications, should not be relayed to the CIPO Canadian Patent Database.
