What is the first step in initiating the email address change process?

Using the Change Address or Representation form is the correct approach to initiate the email address change process. This form is specifically designed for notifying the USPTO of changes related to an applicant's contact information, including email addresses. By submitting this form, applicants can ensure that their information is updated in the USPTO records appropriately.

Other options, such as filing a new application, are not necessary for simply changing an email address and could complicate the applicant's file. While contacting the USPTO directly might provide some guidance, it would not formally process the email change. Waiting for confirmation of the new email does not make sense as a first step because the change process must be initiated before any confirmation can be expected. Thus, the most efficient and correct step in changing an email address with the USPTO is to use the designated form.
