How do I pay for a PCT submission?

Applicants may pay the international application fees online by credit card, deposit account authorization, or electronic funds transfer using the fee payment functionality of EFS-Web, or by including in the EFS-Web submission a signed RO/101 Annex (Fee Sheet) containing authorization to charge fees to a deposit account. Payment may also be mailed, hand delivered, or sent via facsimile (except for payment of the U.S. basic national fee necessary to enter the US national stage, as specified in 37 CFR 1.495(b), which may NOT be submitted by facsimile. See 37 CFR 1.6(d)(3)). See PCT Legal Administration for further information.
