What is the deadline for submitting a certified copy of a foreign priority application?
The deadline for submitting a certified copy of a foreign priority application depends on the filing date of the U.S. application. According to MPEP 213.02:
In the case of a U.S. application filed on or after March 16, 2013, the certified copy must be filed within the later of four months from the actual filing date of the application or sixteen months from the filing date of the prior foreign application.
If the certified copy is not filed within this timeframe, the applicant must file a petition to accept a delayed submission and pay the associated fee.
