Manual of Patent Office Practice (MOPOP)

The Manual of Patent Office Practice (MOPOP) is a guide for patent examiners, applicants, agents and the public looking for information about the operational procedures and examination practices of the Canadian Intellectual Property Office (CIPO).

On this page:

The practices set out in the MOPOP are CIPO's interpretation of the Patent Act, Patent Rules and jurisprudence as of the date each chapter came into effect.

This manual is a guide only and should not be considered legally binding. If you find any difference between this guide and the applicable legislation, you must follow the legislation.

We update the manual from time to time to reflect changes to Canada's patent statutes, regulations and jurisprudence.

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

You can find information about future updates to this manual, including periods of public consultation, on the MOPOP updates page.
