How many secondary correspondence email addresses can be designated in trademark filings?

In trademark filings, applicants can designate up to four secondary correspondence email addresses. This provision allows trademark applicants flexibility in managing communications from the United States Patent and Trademark Office (USPTO). Having multiple secondary email addresses ensures that vital information regarding the trademark application can be received and monitored by different members of an applicant's team or by outside counsel, thus enhancing the likelihood of effective communication.

This capability reflects the USPTO's effort to accommodate the needs of applicants in a digital and collaborative environment. The designated email addresses can be utilized for various correspondence related to the application, such as official notices, updates, and requests for information, which is crucial for the timely management of the trademark process.
