When applying for federal trademark registration with the U.S. Patent and Trademark Office (USPTO), you must list the specific goods/services for which registration is sought.

• If based on use in commerce, you must already be using the mark in commerce on or in connection with all the goods and/or services listed.
  
• If based on intent to use, on a foreign application or registration, or on a request for extension of protection of an international registration to the United States, you must have a bona fide intention to use the mark in commerce on or in connection with all the listed goods and/or services.

When specifying the goods and/or services, use clear, concise terms, i.e., common commercial names and language that the general public easily understands. If you fail to list any recognizable goods or services, we will return your application and refund your fee.

Please note that the terms in the classification listing of goods and services in the USPTO's "International Schedule of Classes of Goods and Services" are generally too broad and should not be used alone as an identification. Also, an international class number alone is never an acceptable listing. For a listing of acceptable wording for goods and services, see the USPTO's Acceptable Identification of Goods and Services Manual, at http://tess2.uspto.gov/netahtml/tidm.html.

Can I change the goods and/or services after filing my application?

You can clarify or limit the goods and/or services. However, you may not expand or broaden the identification of goods and/or services after filing the application.
