Book excerpt: When the fuzz from his sweater was pulled off by a brick wall he was leaning against, Maurice Kanbar had a brainstorm. Soon he had patented, produced and successfully promoted the D-Fuzz-It sweater comb, and made his first fortune at the age of twenty-two. In this engaging “master class” Kanbar’s real world hits and misses illustrate the concrete steps every inventor must follow to successfully take his product to market.
