How is a name change submitted to the USPTO?

A name change can be submitted to the USPTO through the Assignment Center or by mail, making this the correct answer. The reasons for this process are grounded in the flexibility and accessibility the USPTO provides for trademark owners.

Using the Assignment Center allows trademark owners to electronically file assignments and updates, which streamlines the process and is generally quicker than traditional mail. However, submitting by mail remains an option for those who may prefer a paper filing method or do not have access to online submission.

Other choices suggest limitations that do not reflect the USPTO's actual procedures. The notion that name changes must be done only through an online portal or only by mail restricts the available options. Stating that it can be done solely through a legal representative is also misleading, as trademark owners can independently manage their registrations and submissions, including name changes. This ensures that trademark owners have multiple avenues to manage their trademark registrations effectively.
