To submit a Third-Party Preissuance Submission, sign on to EFS-Web and select the “Existing application/patent” option. The Web screen will expand to display additional options. Select the “Third-Party PreissuanceSubmission under 37 CFR 1.290” option and enter the Application Number and Confirmation Number. The Confirmation Number can be obtained by viewing the application in the PAIR System. This places the submission in a segregated area separate from the application file. After review by appropriate USPTO personnel, the submission may be placed in the application file.
