Canadian and U.S. Patent Maps

Several years ago I created a map of the U.S. showing the ratio of issued patents to population. I've recently updated it with 2006 statistics and created a second map for Canada. They're simple maps based on the most recent data from the USPTO and Census Bureau, Canadian Intellectual Property Office and Statistics Canada.

U.S. Patent Map (2006)

The average for the U.S. is 32 patents per 100,000 population. The states with the highest rates are concentrated, as would be expected, in New England, the Pacific Northwest and West Coast. The states with the lowest rates are located in the Deep South, Appalachia, the northern prairies, Alaska, Hawaii and Puerto Rico.

Canadian Patent Map (2005)

Canada's national average is only 4.52 patents per 100,000 population. It must be noted, however, that Canadian inventors file 3 times as many patent applications in the U.S. as they do at home. The lowest rates occur in the maritime provinces of Nova Scotia, New Brunswick, Prince Edward Isle and Newfoundland Labrador. Ontario and Quebec, where most of Canada's manufacturing and high tech companies are located, score 4.72 and 4.47, respectively. The Yukon rate of 12.86 is due to its very small population.
