human: An application for patent term adjustment cannot be filed before a Notice of Allowance has been mailed. If a contents error is noted in the Office Patent Application Location and Monitoring (PALM) records when they are viewed using the Patent Application
assistant: If the error is a contents entry other than the filing date of an application, including a Continued Prosecution Application (CPA), contact the Customer Service Representative (Representative) for the Technology Center (TC) where your application is assigned. If you are alleging that the date shown in Patent Center or Private PAIR  is an incorrect date, then the Representative may need documentary evidence (e.g., an Express Mail label or a post card receipt) showing that the paper was received on a certain date. Note that the certificate of mailing date (which may be relied upon for timely filing purposes) is not retained in the USPTO PALM records, and that the date a paper is received is the date that the USPTO actually received the papers, unless the paper was filed using Express Mail under 37 CFR 1.10. The Representative will obtain the application file wrapper and determine whether there is an error in the USPTO's records. If there is a date error, the records will be corrected.
If the error is in the filing date of an application, including a CPA, a filing date petition is required. Contact the Office of Petitions by telephone at (703)305-9285 or by fax at (703)308-6916 for further information. If a telephone call is made to correct an Office PALM record, other than correcting such an error, no entries are made in PALM (the computer system used to calculate the Patent Term Adjustment), and there would be no reduction to any patent term adjustment. Note a reduction may apply if applicant repeatedly calls the customer service center concerning an application making frivolous requests, and the processing of the application is delayed. If applicant submits a letter with documentary evidence requesting that the Office PALM records be corrected, this letter is matched with the application, and the letter should be entered in PALM. Such a letter would generally not cause a reduction in PTA, however, if applicant were to repeatedly ask for the date to be changed to the certificate of mailing date, or any other improper date, or file such a letter after allowance, the PTA would be reduced under 37 CFR 1.704(a). There is no fee if the above procedure is followed. The above procedure (of contacting the Customer Service Representative) is not permitted after a notice of allowance has been mailed because the application is forwarded to the Office of Patent Publication after allowance, and thus is not readily available to the TCs. In addition, after a notice of allowance has been mailed, an application for patent term adjustment (and the fee) must be filed to have Office records corrected if the change results in a need to recalculate the patent term adjustment. See 37 CFR 1.705(b).
