How is the application size fee calculated for a PCT national stage application in the US?

The application size fee for a PCT national stage application in the US is calculated based on the international application as published by WIPO under PCT Article 21. MPEP 1893.01(c) provides specific details on this calculation:

“The application size fee is calculated on the basis of the number of sheets of specification (including the description, claims, abstract, and, if present, a sequence listing in portable document format (PDF)) and drawings present in the published international application. This calculation is made without regard to the language of publication.”

It’s important to note that certain elements are not included in this calculation, such as Article 19 amendments, the international search report, and additional bibliographic sheets. Article 34 amendments and preliminary amendments are also not considered in determining the application size fee.
