Changes to the Patent Rules introducing excess claims fees and limitations on the number of office actions provided per request for examination (see our article for details) will come into force on October 3, 2022. These new provisions of the Rules will apply to all applications in which a request for examination is made on or after the coming-into-force date.

The goal of these new Rules is to streamline the examination process, in anticipation of the Canadian Intellectual Property Office's (CIPO) obligation to introduce Patent Term Adjustment (PTA) provisions into Canadian Patent Law under the Canada-United States-Mexico Agreement (CUSMA).

At my firm we suggest that clients consider filing a request for examination before the new Rules come into force, if they wish to avoid excess claims fees and limitations on the number of office actions per examination request. To avoid the expected rush for filing a request for examination, requests should be considered as soon as possible if this is of interest.
