To which Office should I pay the international search fee?

The international search fee has to be paid to the receiving Office. For information as to the currencies accepted by IP Australia, see the PCT Applicant’s Guide – Australia (Annex D).

If you file your application with the International Bureau (IB) of WIPO as receiving Office, you can pay the search fee directly to the IB in Euros (EUR), Swiss francs (CHF) or US dollars (USD).

The equivalent amounts in each of those currencies are indicated in the PCT Fee Table, published monthly by the IB in the PCT Newsletter.
