How can one access information about their trademark registration status?

Accessing information about a trademark registration status can be done effectively by contacting the Post Registration Division. This division is specifically tasked with handling inquiries related to registered trademarks, including providing updates on status, pending actions, and compliance requirements. By reaching out to this division, trademark owners can get detailed and authoritative information tailored to their specific registrations.

The other options, while related to trademark operations, do not directly serve as resources for checking registration status. For instance, the Public Search Facility is mainly for conducting searches of trademark records but does not handle the specifics of registration statuses; the Trademark Trial and Appeal Board focuses on appeals and oppositions rather than registration inquiries; and the Madrid Processing Unit deals with international trademark applications under the Madrid Protocol and may not provide status information on domestic registrations. Thus, the Post Registration Division is the most suitable choice for accessing trademark registration status.
