human: How do I file an express abandonment to avoid publication?
assistant: A petition to abandon an application to avoid publication under 37 CFR 1.138(c) and the fee (currently $130) set forth in 37 CFR 1.17(h) may be filed if there is sufficient time (i.e., more than 4 weeks) to permit the appropriate officials to recognize the abandonment and remove the application from the publication process, i.e., the petition must be received by the Office of Patent Publication no later than four weeks before the projected publication date. The petition will not be granted unless the petition and the fee are received more than four weeks prior to the projected date of publication (found on the filing receipt). The petition and the fee (or an authorization to charge the fee to a deposit account) should be mailed to Mail Stop Express Abandonment Commissioner for Patents, P.O. Box 1450 Alexandria, VA 22313-1450, or faxed to the Office of Patent Publication, PGPub Division, at (703) 305-8568.
