Changes to which information can be handled with the appropriate change request?

The correct response focuses on the owner information and contact details as changes that can be facilitated through the appropriate change request. In trademark registration processes, the USPTO allows for updates to the registrant's contact information, including the name and address, especially when there's a change in ownership or if the provided details are outdated. This is crucial for maintaining accurate records and ensuring that all correspondence regarding the trademark reaches the rightful owner.

In contrast, modifications to the design of the trademark logo generally fall under a different procedure. If a trademark's design is altered significantly, a new application might be required to protect the modified logo adequately. Similarly, changes to the types of goods or services offered under the trademark, or its classification, typically necessitate more complex amendments or new filings. Therefore, while updates to ownership details can be streamlined through a change request, changes to the logo, goods or services, and classification often require additional steps, underscoring why owner information and contact details are uniquely positioned for straightforward updates.
