This manual lists numerous examples of identifications of goods and services that are acceptable to the USPTO for inclusion in trademark applications and registrations. The Acceptable ID Manual is not exhaustive and is meant to be a guide to aid applicants and their attorneys in formulating acceptable identifications of goods and/or services.
Yaymark provides a free Goods/Services Search tool that includes all entries from the Acceptable ID Manual. Users may formulate a list of potential identifications of goods/services grouped by class. This tool will help you figure out how many classes and which goods/services you may want to include in a trademark application.
