This is a revised and considerably enlarged edition of a book published in 1979 by McGraw-Hill ( LJ 7/79). It is more thorough and provides better coverage of peripheral topics (e.g, how to keep lab notebooks, marketing and licensing inventions) than Kenneth Norris's The Inventor's Guide to Low-Cost Patenting ( LJ 7/85).
