To whom should you reach out for questions related to ESTTA?

The ESTTA Assistance Center is the correct point of contact for questions related to the Electronic System for Trademark Trials and Appeals (ESTTA). This center is specifically designed to support users with queries about the ESTTA system, including issues related to filings, forms, and technical problems that may arise during the application process. By reaching out to the ESTTA Assistance Center, users can receive specialized guidance and support tailored to the nuances of the ESTTA system.

While the other options may provide assistance for various trademark-related inquiries, they are not specifically focused on the ESTTA system. The Public Search Facility is primarily for searching trademark databases, and the Trademark Assistance Center addresses general trademark questions, while the Madrid Processing Unit deals with international trademarks under the Madrid Protocol. Each has its own area of expertise, making the ESTTA Assistance Center the most appropriate choice for issues specifically related to ESTTA.
