If additional information regarding the status of an application or registration is needed, applicants or registrants may contact the Trademark Assistance Center (TAC) by email at TrademarkAssistanceCenter@uspto.gov or telephone at (571) 272-9250 or (800) 786-9199. TAC staff also provide general information about the trademark registration process. See the USPTO website at https://www.uspto.gov/learning-and-resources/support-centers/trademark-assistance-center for TAC operating hours.

TAC staff will gladly answer questions about the application process. However, USPTO employees cannot:

1. conduct trademark searches for the public (see TMEP §104);
2. comment on the validity of registered marks (see TMEP §1801);
3. answer questions as to whether a particular mark or type of mark is eligible for registration;
4. offer legal advice or opinions about common-law trademark rights, state registrations, or trademark infringement claims; or
5. aid in the selection of a private trademark attorney or search firm (37 C.F.R. §2.11(a) ).

See TMEP Chapter 1800 regarding public inquiries about applications and registrations.
