401.04 Creation of Application Records
For TEAS applications, the USPTO maintains an electronic record containing all incoming and outgoing documents. See TMEP §402.
For paper applications, the USPTO scans all incoming documents and creates an electronic record. The USPTO also creates a paper file jacket and places all incoming documents into the file jacket. The examining attorney works from the electronic record, and outgoing communications are put into the electronic record only.
All applications are electronically routed to the law offices.
