A KTEP Ahead: Canada's New Mechanism For Advanced Examination Of Patent Applications

For a Canadian patent application to be examined, an applicant must file a request for examination with the Canadian Intellectual Property Office (CIPO). In most cases, the order in which applications are examined is based on the order that the requests for examination are received.
