The Web 85b option is NOT available if a filer with a power of attorney wishes to apply a previously paid issue fee to the current issue fee due AND pay a deficiency by any method other than a deposit account number (e.g., credit card, EFT).
In such a case, the filer may file an issue fee payment by filing a follow-on submission with a PTOL/85b attachment under the EFS-Web option “Existing application/patents/proceeding>Documents/Fees for an existing application/proceeding.”
