One of our listserv members says, "In EFS-Web each ack receipt gets a file name that is unique. Patentcenter always tries to give the same name (N417) to every ack receipt. What Patentcenter should do is give a unique name to each ack receipt. The source of uniqueness in the file name for the ack receipt could be the application number or the docket number or even the patentcenter submission number." This is Patentcenter Feature Request FR40 in the PatentCenter Feature Request web page maintained by the PatentCenter listserv at https://patentcenter-tickets.oppedahl.com/patentcenter-feature-requests/.
