What is a necessary step to take if you want testimony from a TTAB proceeding?

The correct course of action when seeking testimony from a Trademark Trial and Appeal Board (TTAB) proceeding involves specifically requesting the information through formal channels. This process typically includes contacting the USPTO with detailed information about the proceeding in which you are interested. By emailing the USPTO and providing specific details, such as the case or proceeding number and relevant parties involved, you ensure that your request is accurately considered and processed by the appropriate authorities.

While contacting the TTAB directly might seem like a straightforward option, the proper protocol is to go through the USPTO, which can appropriately direct your request. Similarly, obtaining testimony from the TSDR (Trademark Status and Document Retrieval) database is not a viable step in this context, as TSDR primarily provides status updates and publicly available documents, but does not house testimony records. Finally, relying on a notice from the TTAB is not a proactive approach to obtaining testimony; this option is not typically how testimony is accessed or requested. Therefore, the most effective way to pursue this testimony is indeed through formal communication with the USPTO, making that option the correct choice.
