Manual of Patent Office Practice (MOPOP)


    The Manual of Patent Office Practice (MOPOP) is a guide for patent examiners, applicants, agents and the public to the operational procedures and examination practices of the Canadian Patent Office.

    Practices expressed in the MOPOP arise from the Office's interpretation of the Patent Act, Patent Rules and jurisprudence as of the date each chapter came into effect.

    This manual is solely a guide and should not be considered to be a binding legal authority. In the event of any inconsistency between this guide and the applicable legislation, this legislation must be followed.

    The manual is updated periodically to reflect changes to the statutory, regulatory and jurisprudential framework governing patents in Canada.

    Please note that the current version of the MOPOP does not cover all practices relating to the prosecution of applications filed prior to October 1, 1989.

    Information regarding forthcoming updates to this manual, including periods of public consultation, may be found on the MOPOP Updates page of this website.
