Your USPTO: DOCX Streamlines Patent Filing Process
Now you can file patent application-related documents in this word-processing file format through EFS-Web, Private PAIR, and Patent Center. To improve application quality and efficiency, the USPTO will transition to DOCX for all filers on Jan. 1, 2022. PDFs will continue to be an option; however, a non-DOCX surcharge fee will be effective on that date.
