What is a secondary correspondence email address in trademark filings?

The definition of a secondary correspondence email address in trademark filings refers to it as an additional email address intended for sending courtesy copies of communications. This means that while the primary email address is where official communications are sent, a secondary correspondence email allows for extra notifications or copies to be sent to another address. This can be particularly useful for keeping stakeholders informed about the status of a trademark application or any correspondence from the USPTO without having to rely solely on one email address.

The other options highlight different types of email functions but do not accurately represent the purpose of a secondary correspondence email address. The main email address is used for all official communications; an emergency contact email may not specifically relate to trademark matters and implies an urgency that isn't covered by the notion of secondary correspondence; and a backup email address for technical failures suggests a redundancy for reliability rather than a shared or secondary notification system. Thus, the selection of the secondary correspondence email as a means for receiving courtesy copies precisely captures its intended function within trademark filings.
