To which Office should I pay the international search fee?
If you file your application with the CNIPA as receiving Office, you must,
- for any application filed on or after 1.12.2024: pay the international search fee directly in Chinese Yuan (CNY) to CNIPA.
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.
