James Henry Atkinson from Great Britain invented the spring trap called the "Little Nipper" in 1899 and this same design still captures 60% of the mousetrap market today. Since then there have been close to 5000 patents on mousetraps but only about 20 of those are actually being sold as products today. This book contains 50 mousetrap patents. Can you build a better mousetrap?
