110.04 Questions About ESTTA Filing
Filers may call the Board with questions about filing at (571) 272-8500 or (800) 786-9199 (toll free) from 8:30 a.m. until 5:00 p.m. (Eastern Time). Alternatively, filers may send non-urgent email inquiries to ESTTA@uspto.gov, and include a description of the problem, the ESTTA tracking number and Board proceeding number (if any), and a telephone number for contact. The Board will respond to email inquiries within two business days. The email address is for technical ESTTA questions only. Submissions will not be accepted for filing by email. See TBMP § 107 ("The Board does not accept any filings by email.").
ESTTA users are encouraged to contact the Board when ESTTA is not working as expected. Whether or not one is able to overcome a problem, others are likely to have similar difficulties. Absent notification by users, the Board may be unaware of the problem, delaying any necessary repair.
