When is the deadline for paying the basic national fee for a PCT application entering the US national stage?

The deadline for paying the basic national fee for a PCT application entering the US national stage is 30 months from the priority date. This is a critical deadline that must be met to avoid abandonment of the application.

As stated in MPEP 1893.01(c):

“The basic national fee must be paid prior to the expiration of 30 months from the priority date to avoid abandonment of the international application as to the United States. This time period is not extendable.”

It’s important to note that this deadline cannot be extended, so applicants must ensure timely payment to maintain their patent rights in the United States.
