Canadian Patent Examination Will Soon Be More Expensive, Less Flexible and Require Additional Care in Prosecution to Avoid Loss of Rights

Canadian Patent Examination

Significant fee increases will be effective at the Canadian Intellectual Property Office (“CIPO”) on October 3, 2022 related to excess claims (claims over 20) and the number of examination reports it issues during prosecution. These changes may negatively impact the breadth of patent protection an applicant could pursue in Canada and will likely also require additional care in strategic filing choices during patent examination. Prior to October 3, 2022, applicants should consider requesting examination for pending applications in order to minimize the impact of these fees (the fee increase will not apply to patent applications for which a request for examination is filed prior to October 3, 2022).
