How are patent applications initially processed by the USPTO?

Patent applications are initially processed by the USPTO through electronic scanning and loading into the Image File Wrapper (IFW) system. According to MPEP 508, “All applications are electronically scanned and loaded into the Image File Wrapper (IFW) system upon filing. Once documents are loaded into the IFW system, examiners, technical support staff, and other Office personnel will perform further processing and examination using the IFW system.”
