The Canadian Patent Office is currently undertaking an extensive review of the Patent Rules. Among changes proposed is an amendment related to section 6, which currently states that for the purpose of prosecuting or maintaining an application, the Commissioner shall only have regard to communications received from the authorised correspondent which, when appointed, is the patent agent. This has been found to be problematic in circumstances where the Office has received clear instructions from an agent, but could not give consideration to the instructions since the agent was not appointed as the authorised correspondent.
