Consultation and discussion

The Canadian Intellectual Property Office (CIPO) is holding a first consultation on the international harmonization of patent law.

Group B+ and Group B+ sub-group

The World Intellectual Property Organization (WIPO) has been host to patent law harmonization talks for over 30 years. In the 1990s, these talks focussed on patent formalities issues and led, in 2000, to the adoption of the Patent Law Treaty (PLT). Canada signed the PLT in 2001 and is in the process of implementing the treaty.

In November 2000, the WIPO Standing Committee on the Law of Patents (SCP) resumed work on the development of a substantive patent law harmonization treaty. To promote and facilitate progress on key issues under consideration at the SCP, the Group B+ was established.

In 2014, the chair of the Group B+ set up a sub-group to further advance work on the following topics:

Canada is part of the Group B+ sub-group and has been involved in the work and information-sharing that led to the development, by the chair, of a paper presenting the findings of the sub-group with respect to these five topics. Objectives and principles guiding substantive patent law harmonization have been identified and presented in the same paper.


CIPO is reaching out to the public and, in particular, industry members, to provide comments that will be valuable in informing the next stages of the harmonization talks in the context of the sub-group and of the Group B+. CIPO will be conducting more consultations as the work of the sub-group moves forward.
