This page is an FAQ based on guidance from the Manual of Patent Examining Procedure. It is provided as guidance, with links to the ground truth sources. This is information only: it is not legal advice.

Failure to timely submit the reference to the prior-filed application within the time periods specified in 37 CFR 1.78 is considered a waiver of any benefit claim under 35 U.S.C. 120, 121, 365(c), or 386(c) to the prior-filed application. See 37 CFR 1.78(d)(3)(iii). The time periods are not extendable.

If the reference to the prior-filed application is submitted after the time period provided by 37 CFR 1.78, a petition and the petition fee under 37 CFR 1.17(m) would be required to accept the delayed claim. The petition must be accompanied by:

  • The reference required by 35 U.S.C. 120 and 37 CFR 1.78 to the prior-filed application
  • The petition fee
  • A statement that the entire delay between the date the benefit claim was due and the date the claim was filed was unintentional
