Trademark Information


A trademark is any word, name, symbol, or device, or combination of these, adopted and used to identify the goods or services of a business and distinguish them from those offered by others. Trademarks may be registered with the United States Patent and Trademark Officeexternal link collection (USPTO), with state trademark offices or left unregistered.

Information on how to register a Federal trademark and answers to many questions about them can be found at the USPTO's Trademark Basics pageexternal link collection.

Trademark Searches

Searches of trademarks registered with the USPTO may be done at no charge online at the USPTO Web siteexternal link icon. They may also be done at no charge at the New York State Library. Staff at the New York State Library can assist you in formulating search strategies and in searching for logos.

New York State Library staff is available to assist you in using the trademark search tools. The staff are not, however, patent or trademark attorneys, and are not qualified to provide legal advice, interpret your search results or strategies, or provide opinions on the viability of a trademark application.

A directory of attorneys and agents registered to practice before the USPTO can be found on the USPTO Web site at Registered Attorney/Agent Searchexternal link icon.

A search can be used to:

  • Find out if a mark you would like to use has already been registered
  • Generate ideas for the design of a new mark
  • Determine a trademark's appearance, date of issue, or holding company
  • Watch for infringement of trademark rights
  • Collect information in support of litigation
  • Keep abreast of the introduction of competitive products and services
  • Find out who owns what
