Patent Administrative Status Data Dictionary

This element contains all the information on a patent.

"lang" contains the language of the publication.

"kind" contains the kind code according to WIPO Standard ST.16. See the Kind Code element for the code descriptions.

"doc-number" contains the number assigned to the patent (Patent number).

"status" contains the code indicating the current processing state of the Patent/Application. See Appendix B

"dtd-version" contains the document type dictionary version. For clients performing bulk processing of CIPO's ST.36 Patent XML files - either transformation or validation - the public Document Type Definition http://patents.ic.gc.ca/cipo/dtd/ca-patent-document-v2-0.dtd should be downloaded and added to their local XML Entity Catalog. Doing so will avoid an inordinate number of HTTP Get requests for the DTD and the possibility of being refused access to CIPO's web site as a potential denial-of-service threat.

"country" contains the country code (WIPO ST.3) of the publication country (Canada).

The date where the patent application met the legal requirements for a filing date under the Canadian Patent Act. If it is a PCT originating application, then it is the same date as the PCT filing date.^{Footnote 2}

For divisional patents, where the application was filed before October 1, 1989, the date recorded as the filing date may be the date the divisional application was received, rather than the legal filing date of the parent application. Similarly for reissue patents, where the application was filed before October 1, 1989, the date recorded as the filing date may be the date the request for reissue was received, rather than the legal filing date of the surrendered patent.

(41) Open to Public Inspection (OPI)

(87) PCT Publication Date

Patent applications filed since October 1, 1989, are open to public inspection at the expiry of the confidentiality period referred to in subsection 10(2) of the Act.

Applications filed on or after October 1, 1989, are made available to the public 18 months after the earliest priority date, or, if there is no priority, 18 months after the filing date, unless the applicant has requested an earlier date of opening to public inspection.

If the application is PCT-originating, then the open to public inspection date will normally be the same as the PCT publication date.^{Footnote 4}

The date that a patent was reissued after the original patent was surrendered by the patentee. For patents that were filed on or after October 1, 1989, the patent number remains the same as the original patent. For patents that were filed before October 1, 1989, the patent reissues with a new number. In both cases the term of the patent remains the same as the original patent.

A reissue is a mechanism provided for in section 47 of the Act for correcting a defective or inoperative patent, where any error arose from inadvertence and without deceptive intent. Once statutory conditions are met and further examination is undergone, the Commissioner may cause a new patent to be granted.

On the rare occasion that a patent document may have multiple reissue dates. This site displays only the most recent reissue date. In order to determine if the patent has been reissued more than once, the cover page Image of the patent must be accessed.
