Kanbar, the inventor of the D-Fuzz-It sweater comb and the multiplex cinema and the holder of over 30 patents, offers this chatty guide that aims to demystify the process of inventing, from brainstorming and brand naming to prototyping and patenting. He provides the nuts and bolts of the five basic steps that he's followed and still follows in the wake of the technical revolution wrought by the Internet: solve a problem; build a prototype; protect the idea; decide to either manufacture or license; and market with a twist. Appendices provide lists of resources as well as templates of legal documents and other forms. Annotation c. Book News, Inc., Portland, OR (booknews.com)
