Over the last 40 years, intellectual property has grown from an arcane, narrowly-specialized legal field into a major force in American social and economic life. It comprises an astonishing 45 percent of total U.S. GDP today, and represents 80 percent of the market value of all publicly-traded companies in the U.S. Therefore any young person who fails to grasp at least the basics of intellectual property Ñ and its role in science, business, arts, and the professions Ñ will find him or herself at a distinct disadvantage in the world of tomorrow.
