Industrial designs is the smallest of the product lines in the Canadian Intellectual Property Office and has traditionally played a subsidiary role in CIPO to patents and trade-marks. Prior to CIPO implementing major fee increases in January 2004, the industrial design branch was unable to generate sufficient revenue to even cover its operating expenditures. Further, frequent changes in the director of the industrial design branch in recent years have resulted in a lack of leadership and stability at the head of the branch.
