Canadian Patents DatabaseHelp: Searching
Searching by Patent Document NumberIf you know the patent document number use the Patent Document Number Search The Canadian Patents Database uses 8 numeric digits for all patent document numbers. They can be entered with or without leading zeros, and they should not contain commas. Examples:
Searching for TextYou can search for text in the following fields:
The Boolean Text Search lets you enter text for up to three of the text fields in the database and for one of the date fields. The Advanced Text Search lets you enter text for all of the text fields in your search and for one of the date fields. Examples of Text Field SearchesFor each of the text fields, we have provided a few example searches and some comments. These examples show some of the power of the Canadian Patent Database's search language. SEARCHING THE INVENTOR FIELD Type a portion of a name, a name or multiple names of inventors. Examples :
SEARCHING THE INVENTOR COUNTRY FIELD This option is available only on Advanced Text Search. The Country searching is initiated by selecting one of the Country fields from the pull down box: SEARCHING THE OWNER FIELD Type the word(s) or name you expect to find for the person or organization who owns the patent document or was the grantee owner, see OWNER (Country). Examples :
SEARCHING THE APPLICANT FIELD Type the word(s) or name you expect to find for the person or organization that applies the patent document. Examples :
SEARCHING THE TITLE FIELD Type the word(s) you expect to find in the title. Examples :
SEARCHING THE ABSTRACT FIELD Enter the word(s) or phrases you expect to find in the abstract of the invention. A search on the abstract field will only retrieve laid-open patent applications and patent documents that were granted after August 15, 1978. Examples :
SEARCHING THE CLAIMS FIELD Enter the word(s) or phrases you expect to find in the claims. A search on the claims field will only retrieve laid-open patent applications and patent documents that were granted after August 15, 1978. Examples :
SEARCHING THE CLASSIFICATION FIELD Select the classifications or a portion of the classification under which you expect to find related patent documents. The two latest versions (6 and 7) can be consulted on the WIPO Web site at http://classifications.wipo.int/ Examples:

Searching for specific documentsYou can select specific document in the following fields :
SEARCHING LICENSE AVAILABLE FIELD You can decide to search strictly through patents where the owner voluntarily indicated that he or she is willing to sell or license the rights to the patent. You can search through PCT or Non PCT documents, by default; the search is conducted through All patent documents. SEARCHING BY LANGUAGE OF FILING You can select the language of filing. The default option, "In both languages", allows patent document searches in the whole database. The two other options allow patent document searches within only laid-open applications and patents granted on or after August 15, 1978. Date SearchingYou can search for a specific date or a range of dates in the following fields.
Date searching is initiated by selecting one of the date fields from the pull down box: Date searching is inactive when the pull down box contains the default text, "Date Search Not Active". Date search criteria are always "ANDed" to your text search criteria. The Boolean Text Search lets you enter text for up to three of the text fields and one of the date fields. The Advanced Text Search lets you enter text for all of the text fields in the database and for one of the date fields. Date searches should always be used in conjunction with a text search to avoid long search times. SEARCHING THE DATE FIELD - Examples Select the date field and the desired range. Examples:
Display OptionsBy default, the maximum Results per list is 50 documents. This option lets you define the maximum number of results displayed per list. The results are ranked based on the hit count. Hit count refers to the number of times individual query words or search criteria appear in the selected field(s). The results or hits of your query are displayed on a new screen. This results list may be printed by clicking on the PRINT button of your browser. Single-clicking on one of the patent document numbers will allow you to view the detail of the patent document. This screen has been designed to help the user scan through results relatively quickly and determine if the Patent documents resulting from the search are of interest. The information may be printed by clicking on the PRINT button off your browser. The BACK button of your browser allows you to return to the list of results and continue verifying results in the same manner. By default, the Maximum results per list is 50 documents. Using the First, Previous, Next or Last arrow button, you can access to the other list results: The search engine can display up to one thousand patent documents per query. When the results exceed the maximum, a note appears on the hit lists to recommend that you adjust your search criteria. For example, you can break down your search criteria using the date range. |
