How much is the international search fee?
For applications filed on or after 1 December 2024, for which the international search fee is to be paid directly to CNIPA, the equivalent amount in Chinese Yuan (CNY) has been set at 14 310.
If the search carried out for your international application is based entirely or partly on an earlier search report already prepared by the EPO on an application whose priority is validly claimed (Box No. VI of the PCT request form), you may be entitled to obtain a refund of the international search fee. The EPO acting as ISA decides whether the requirements are met and, if so, refunds the applicable amount.
