Structured Text Filing in the USPTO

To improve application quality and efficiency, the USPTO is to transition to a system that supports submitting new patent applications in structured text, specifically in the DOCX format, for all filers starting January 1, 2022. The DOCX document filed by the applicant will be the authoritative document - accordingly, an applicant who files an application in DOCX may rely on that version as the source or evidentiary copy of the application to make any corrections to the documents in the application file.
