If the examiner has requested an Identification of Goods, they want you to specify or amend some of the goods and services you listed in your application. Along with the request, they’ll typically suggest acceptable alternative language from the USPTO's ID Manual. Your response should include these suggested terms or equivalent language that resolves the specific objection.
The description must be specific enough to define what goods are covered, but not so narrow that it excludes what you actually sell. Acceptable descriptions clearly identify the nature of the goods rather than being too broad. For example, "downloadable computer software for managing customer relationships" rather than "software." Just be aware that your amendment can narrow the original list down to more specific fragments, but it cannot expand it to cover new goods that weren’t within the scope of the original application.
