What is required for each additional extension request filed to keep a trademark application alive?

For each additional extension request filed to maintain a trademark application, the correct requirement is the Additional Extension Request Fee. This fee is specifically designated for the application process and is necessary when an applicant seeks to extend the time to file a Statement of Use or to address outstanding issues related to the application.

The need for this fee arises from the administrative costs involved in processing extension requests, which require examination and may lead to updates in the application status. Each extension conveys a continuation of the application review process, hence justifying the need for a specific fee tied to that action.

Regarding other potential fees, the Standard Filing Fee applies to the initial application submission and would not be relevant to ongoing extension requests. The Publication Fee is associated with the publication of the mark in the Official Gazette once the application is sufficiently reviewed, and it does not pertain to extensions. The Renewal Fee is necessary for maintaining an already registered trademark and is not applicable to extension requests that pertain to pending applications.

Understanding these distinctions is crucial for anyone navigating the trademark application process, ensuring that they comply with all financial requirements at each stage.
