Patent application assistance patent acceptance notice has been received, but the application fee has not been paid. I want to modify the number of claims. Can I make the modification without paying t

Modifications must be within the scope.

Since the fee has not been paid, it is recommended to re-apply. The original application will be considered withdrawn due to non-payment of the fee. Since it has not been made public, it will not affect the review of subsequent applications.

Submitting an application again will have no impact except for the difference in application date.
