    Does the Office permit reinstatement of rights (PCT Rule 49.6)?
    The Office has submitted a notice of incompatibility of PCT Rule 49.6 with its national law. However, the Office does, as a designated office, permit reinstatement of rights under subsection 154(3) of the Canadian Patent Rules.

    Applicants may enter the national phase with untranslated portions of the description or claims only where those elements of the international application are partly in a language other than English or French; however, untranslated text matter will not be taken into account for the purpose of interpreting the scope of protection sought or obtained
    Is a copy of the international application required in particular circumstances?

This may be the case where the applicant expressly requests an earlier start of the national phase under PCT Article 23(2).

    No. Drawings must be in black, sufficiently dense and dark, well-defined lines to permit legible reproduction and must not be photographs (Canadian Patent Rules subsection 59(1)).

    Must be paid within the time limit applicable under PCT Article 22 or 39(1).

    Maintenance fee payments are due on or before each anniversary of the international filing date, starting with the second anniversary. Where the applicant fails to pay by the due date a late payment fee will also be due. A notice will be sent to the applicant indicating that the maintenance fee and the late fee must be paid before the later of six months from the maintenance fee due date or two months from the date of the notice. If the maintenance fee and the late fee are not paid within the late fee period the application will be deemed abandoned or, in the case of a patent, the term limited for the duration of the patent will be deemed to have expired.
