Which of the following is NOT associated with the Trademark Electronic Application System (TEAS)?

The Trademark Electronic Application System (TEAS) is primarily designed to facilitate the filing and management of trademark applications. It allows users to submit new trademark applications, file responses to office actions, and manage various requests related to their trademark filings, which aligns with the functions described in the first three options.

However, TEAS does not directly handle the management of trademark disputes. Trademark disputes, including oppositions, cancellations, or other legal challenges, are typically managed through proceedings in front of the Trademark Trial and Appeal Board (TTAB) or involve litigation in court. Therefore, while TEAS plays a crucial role in the application and registration process, it is not associated with the administration or resolution of trademark disputes, making this option the correct one to identify as not being associated with TEAS.
