When must the specific reference to a prior-filed application be submitted?

The timing for submitting a specific reference to a prior-filed application depends on the type of application:

• For utility or plant applications filed under 35 U.S.C. 111(a): The specific reference must be submitted during the pendency of the application and within the later of four months from the actual filing date of the application or sixteen months from the filing date of the prior application.
• For national stage applications under 35 U.S.C. 371: The specific reference must be submitted during the pendency of the application and within the later of four months from the date on which the national stage commenced under 35 U.S.C. 371(b) or (f), four months from the date of the initial submission under 35 U.S.C. 371 to enter the national stage, or sixteen months from the filing date of the prior application.

It’s important to note that This time period is not extendable and a failure to submit the reference required by 35 U.S.C. 119(e) and/or 120, where applicable, within this time period is considered a waiver of any benefit of such prior application(s).
