The US Patent & Trademark Office (PTO) recently announced that the surcharge fee for patent applications that are not filed in DOCX format will not go into effect until January 1, 2023. During the period before non-DOCX filings are hit with the surcharge fee, the PTO is encouraging applicants to begin filing patent applications in DOCX format (87 Fed. Reg. 25226). To address concerns some applicants have raised and to allow applicants to get acclimated to the process of filing applications in DOCX format, the PTO is providing applicants with the option to submit an applicant-generated PDF version of their application along with the DOCX file(s) when filing an application in the Patent Center without having to pay additional fees, such as application size fees.
Applicants who choose to submit an applicant-generated PDF with the validated DOCX file(s) will be able to rely on the applicant-generated PDF if a discrepancy occurs during the filing process. Once the non-DOCX filing surcharge fee officially goes into effect, applicants who submit an applicant-generated PDF with the validated DOCX file(s) will need to pay the surcharge fee and any other additional fees as a consequence for filing the applicant-generated PDF. This new document description is called “Auxiliary PDF of application,” and the corresponding document code is AUX.PDF.
The PTO advises:
Applicants are strongly encouraged to review their applications, including the USPTO-generated PDF, shortly after filing the application to identify any errors or discrepancies in the record, as discussed above. The applicant should file any necessary petition to correct the record early in prosecution and promptly after discovering any errors or discrepancies.
