On October 3, 2022, amendments to the Canadian Patent
Rules will come into force, introducing changes to
patent prosecution in Canada. The most significant of these changes
are excess claims fees and a new continued examination
procedure.
In general, additional costs and the applicability of new
procedures/actions introduced by the amendments may be avoided by
requesting examination of an application before
October 3, 2022.
Please contact a member of our Intellectual Property Group if you have
any questions about how the amended Patent
Rules may affect your patent applications.
1. Excess Claims Fees
Currently, there is no government fee based on the number of
claims in a Canadian application.
