The Canadian Patent Database contains over 2.2 million patent documents from 1869 to the present. This database is updated regularly with newly granted patents and applications opened to public inspection. Searches are performed against the bibliographic and text data fields only, and a "hit list" of matching patents is returned. Images are not searchable but can be viewed for any particular patent that has been returned in a hit list. The text of the abstracts and claims is not available for patents that were granted prior to August 15, 1978. These patents can only be searched by their patent number, titles, owner, inventor, or classification. Note about completeness of the Date Fields: The issue date is searchable from 1869 to the last updated date. The filing date is not available for patents registered prior to August 15, 1978. The priority date and the national entry date are not available for patents registered prior to October 1, 1989.

Espacenet's worldwide database enables you to search for information about published patent applications from over 90 different countries and regions. Espacenet offers free access to more than 70 million patent documents worldwide--most of them patent applications rather than granted patents--from 1836 today. Patent applications normally represent the first publication of a new idea, appearing ahead of journal articles and before new products reach the market. Other information includes: patent family information, telling you if similar patents have been claimed in other countries; legal status information, helping you find out whether and in what countries a patent is in force; references to other kinds of technical literature (non-patent literature); citing documents (other documents that have cited the document you are looking at); and links to the European Patent Register for European and Euro-PCT documents. It is possible to print and download documents.

The FTSS Recherche database, provided by the Canadian Centre for Occupational Health and Safety (CCOHS), contains French language material safety data sheets for chemical substances manufactured or distributed in North America. The English language database, MSDS, also provided by CCOHS, contains a larger collection of material safety data sheets.
