These practice notices provide guidance on current patent practices and the interpretation of relevant legislation.
Official notices published on this page set forth Office practice as of their publication date. As mandated by the Patent Act and Rules, certain notices will also be published in the Canadian Patent Office Record (CPOR). In the event of any discrepancy between a notice on this web page and one in the CPOR, the version in the CPOR is the official version.
The practice notices below are intended to provide guidance on current CIPO practice and interpretation of relevant legislation and should not be quoted as, or considered to be, a legal authority. In the event of any inconsistency between the notices and the applicable legislation, the legislation must be followed. It is the responsibility of the applicant/patentee to decide how to proceed with respect to a particular application or other matter.
