What are the requirements for sending confidential information via email to the USPTO?

When sending confidential information via email to the USPTO, specific requirements must be met:

• Use of the Electronic Filing System (EFS-Web) is strongly recommended for submitting confidential information.
• If email must be used, it should be through the USPTO’s secure email system.
• An authorization from the applicant is required before sending confidential information via email.
• The email must include a statement that the email correspondence is being submitted using the procedures set forth in 37 CFR 1.33(d).

As stated in MPEP 502.03: “Internet email shall NOT be used to conduct an exchange of communications similar to those exchanged during telephone or personal interviews unless a written authorization has been given.”
