In honour of Canada Day, here are a few Canadian industrial designs that are based on the maple leaf, the national symbol of Canada. All were retrieved from the CIPO’s industrial design database, which includes designs registered from1861 to the present. Unfortunately, CIPO doesn’t classify designs by shape, so the only way to retrieve specific designs is by keyword searching in the title or description field. The designs include a sun visor (71471), sunglasses (24929), poncho (106525), pin (100394) and glove (109475).
