What function does the blue 'Documents' button serve in the TSDR system?

The blue 'Documents' button in the TSDR (Trademark Status and Document Retrieval) system serves the purpose of allowing users to view, download, and print documents related to trademark applications and registrations. This functionality is essential for trademark applicants, registrants, and their representatives, as it provides direct access to important documents such as office actions, responses, and registration certificates. This ability to manage and reference official documents is crucial in the trademark process, enabling users to stay informed about their application status and respond accordingly to any Office actions.

The other options fail to align with the purpose of the 'Documents' button, as initiating a new application, closing the application, or contacting customer support do not pertain to the direct interaction with existing trademark documents, which is the primary function facilitated by that button.
