Any decision on restoration of the right of priority by the receiving Office, which was based on a finding by it that the failure to file the international application within the priority period occurred unintentionally, will be effective, unless the Office reasonably doubts that a requirement referred to in PCT Rule 49ter. 1 (c) was complied with. In such an exceptional case, the Office shall notify the applicant accordingly, indicating the reasons therefo

How can payment of fees be effected?
Payment of the national fee to the Office has to be made in Japanese Yen, by means of patent revenue stamps. The patent revenue stamps can be purchased at major Japan Post Co., Ltd. offices in Japan. The necessary amount of stamps must be affixed to the related form.
Some other payment methods, such as the advance payment system, bank account transfer or online cash transfer, may be available provided that the applicant or their representative in Japan has carried out the necessary registration proceedings at the Office in advance
In principle, the Office does not accept any payments made directly by overseas residents, such as payment by international bank account transfer, or by credit card or by check, therefore, payment by an applicant overseas has to be made through a representative appointed in Japan
However, in the case of patent annuity fees for the 4th year onwards, direct payment by bank account transfer or patent revenue stamps is available for overseas residents. For detailed instructions please refer to:
