We Will Help You Every Step Of The Way


If you already filed a PCT application in your jurisdiction, it is required to file a Petition for Entry within 30 months from the international filing day or the priority date, whichever is earlier.
  • Basic Filing Fee: JPY 60,000
  • Translation Fee: JPY 25 (per English word)
  • Government Fee: JPY 14,000
A Request for Examination must be filed within 3 years from the international filing date. A Japanese patent application will not be examined unless a Request for Examination is filed. If examination is not requested in time, the application will be regarded as having been withdrawn.

We receive a first Office Action from the Japan Patent Office usually within 10-12 months after the request for examination. We receive at least one office action in almost every case.

If the examiner considers that the application is in condition for allowance, we receive a Decision to Grant, and we have to pay the first three annuities within 30 days.
The answer is No. Once you file a Petition for Entry to validly enter the national phase, it is possible to file a Japanese translation of a PCT application later, within 2 months from the date on which the Petition is filed.

Yes, in such a case, we basically file your translation as-is received, but please allow us to charge our attorney fee of JPY 15,000 so that we can review the Japanese translation to satisfy the JPO’s formality requirements and draft figures if necessary. Accordingly, the estimated costs would be:

  • Basic Filing Fee: JPY 75,000
  • Government Fee: JPY 14,000
  • Attorney’s Fee: JPY 30,000
  • Government Fee:

    • JPY 106,000 + JPY 3,600 x N (number of claims); or
    • JPY 124,000 + JPY 3,600 x N (for application filed on or after April 1, 2019)

Please note that the Government Fee is calculated simply based on the number of claims, regardless of the number of independent claims, multiple dependent claims, etc.

Further, the Government Fee changes based on the international filing date, ISR, etc. For more details, please contact for specific quotation. 

For our fixed plan, our attorney’s fee would be:

  • Subtantive Office Action: JPY 140,000
  • Non-Substantive Office Action: JPY 60,000 

The term for filing a reply is 3 months, which may be extended up to 6 months at maximum. In case of obtaining extension of term,  the estimated costs per each filing would be:

  • Attorney’s Fee: JPY 4,000
  • Government Fee: JPY 2,100
  • Attorney’s Fee: JPY 30,000
  • Government Fee: JPY 6,300 (basic fee) + JPY 600 x N (number of claims)

If you have any questions that we have not been able to answer, we would love to hear from you.
