Stoppage of 2 CIPO patent reminder notices (2020-02-25)

From: Canadian Intellectual Property Office

The Canadian Intellectual Property Office (CIPO) will no longer send annual patent maintenance fee reminder notices advising that maintenance fees must be paid by a certain date. It is your responsibility to pay patent maintenance fees before their deadlines.

CIPO will also no longer send letters reminding applicants that a request for examination of a patent application must be filed by a certain date. You must submit a formal request for examination to CIPO and pay the prescribed fee within 4 years of your filing date.
