Can I add new products or services to an existing registration?

Generally, no. You can narrow or delete goods or services from an existing registration, but you cannot expand the registration to cover additional goods or services outside its existing scope. New goods or services generally require a new application.

Trademark ownership generally belongs to the person or legal entity that controls the nature and quality of the goods or services sold under the mark. An assignment transfers ownership from one party to another. A license, by contrast, gives another party permission to use the mark while the original owner keeps ownership.

Ownership changes should be documented carefully because trademark rights are tied to the goodwill of the business. 'Goodwill' means the customer recognition and reputation associated with the mark. A trademark generally should not be transferred as an empty symbol disconnected from the business and goodwill it represents.
