human: When will my petition be accorded a filing date?
assistant: Once the Office reviews the petition and determines whether the petition is complete and the appropriate fees have been paid, the Office will send a notice to the petitioner and patent owner/respondent. The submission date of the compliant petition will be accorded as the filing date. If the petition complies ewith all of the statutory requirements (see 35 U.S.C. 135, 312, and 322), the original submission date of the petition will be accorded as the filing date. Conversely, no filing date will be accorded if a statutory requirement is not satisfied. For example, for fee deficiencies, the Office will accord the later submission date when all appropriate fees have been paid because the fees are  required by statute. See, e.g., 35 U.S.C. 312(a)(1). In the situation where a petition complies with all the statutory requirements but contains only regulatory defects, the Office will accord the filing date of the original submission and notify the petitioner of the defects. The regulatory defects must then be corrected within the time period set forth in the notice.
