Advanced technology has resulted in the proliferation of all kinds of popular symbols and illustrations; but sorting out which are protected by the law, and which are merely familiar scribbles can be a confusing and laborious task. This question is answered, as well as many others about contemporary trademark law, in this accessible guide by Timothy Wherry. Information seekers are directed through the process of verifying that a trademark is registered, and given a history of the trademark and important trademark court cases. A useful FAQ section answers some common questions about trademarks. Wherry's work also includes useful listings of U.S. and international trademark classifications, and is a fitting tool for entrepreneurs, librarians, and law students alike.
