The laws covering intellectual property--those products of the imagination with commercial value, such as fictional writing, software designs, product names, and mechanical inventions--have long boggled the minds of the uninitiated. With the advent of online commerce and publishing, the issues have only gotten more confusing. The new edition of Patent, Copyright & Trademark: A Desk Reference to Intellectual Property Law, by attorney Stephen Elias, offers plain-English explanations and practical advice on this increasingly complex topic. Elias covers everything from the laws themselves to their specific applications in different media.
