"Now in an updated ninth edition covering recent changes in patent law and regulations, including the new "first to file" rules, Nolo's Patents for Beginners lives up to its titles as a thoroughly accessible "must-read" for inventors. Chapters cover patent law basics, the implications of the America Invents Act, how to document an invention, how to "read and write" patents, the basics of patent infringement, provisional patents, and much more. A glossary, an index, and a wealth of examples round out this excellent, user-friendly guide that can potentially make the difference between earning a fortune off one's ideas and watching someone else earn a fortune instead. Nolo's Patents for Beginners is highly recommended both for public library and personal reference collections." The Midwest Book Review
