The required documents differ according to the the filing manner.

PCT route filing

The following documents are required for PCT route filing. PCT route filing is the manner to enter an international patent application into the domestic phase in Japan.

These documents prepared in English or Japanese need to be sent to us.

PCT route filing

1. Information sheet

The information sheet is required to specify at least the following information.

(a) Reference number in your firm
(b) Application number and filing date of the international application
(c) Title of invention
(d) Names and addresses of all applicants

If the language of names and addresses is neither Japanese nor English, it is desirable to write not only the spellings but also the pronunciations thereof. Especially, the pronunciations are desirable to be written by Japanese Katakana, if possible.

(e) Names and addresses of all inventors

Same as the above (d).

(f) Priority information

If the international application has claimed the priority right, the priority information is required. The priority information needs to include at least the date, number and country of the earlier application which serves as the basis of the priority right. If claiming more than one priority right, information concerning all priority rights is required.

2. Front-page of international publication

It is required to send us at least a front-page of the international publication for the application. We can download whole of the application documents from WIPO website by referring to the information sheet. However, the front-page provided from you is useful to identify the international patent application more certainly.

3. Amendment under Article 19 or 34

Amendment under Article 19 or 34

After you have made non-Japanese amendment under Article 19 or Article 34 in the international phase, if you fail to file a translation thereof to the JPO within 30 months from the priority date, the amendment shall be deemed not to be filed. Furthermore, when you file the translation, it is required to file a brief explanation showing the basis for the amendment in the application documents at the international filing date.

Therefore, if you hope to reflect the amendment on the domestic phase, it is required to send us a copy of the amendment and the brief explanation concerning the basis for the amendment.

In contrast, even if you have made amendment under Article 19 or Article 34, if you don't hope to reflect it on the domestic phase, it is unnecessary to send it to us.

(a) Confirmation letter

If we receive a filing request from the first-time customer, we will send a confirmation letter to the customer. If you receive our confirmation letter, your reply to the letter is required.

(b) Clear drawings

As mentioned above, the application documents are not required. However, if you have clear drawings more than the international publication, it is desirable to provide them to us. Especially, it is more desirable, if that is an electronic version.

(c) Power of attorney

A power of attorney isn't required at entry into the domestic phase. In Japan, a power of attorney is required only at the particular procedures. Therefore, a power of attorney isn't required in almost all cases, so that we don't recommend early filing.

(d) Instruction of request for examination

Your instruction to file the request for examination is not required. The request for examination is due to be filed within three years from the priority date. That is, in the case of the international application, usually it should be filed within six months from domestic phase entry. Therefore, not receiving a contrary instruction from you, we request the substantive examination shortly after domestic phase entry.

Paris convention route filing

The following documents are required for Paris convention route filing. Paris convention route filing is the manner to file a patent application claiming one or more priorities under the Paris convention. These documents prepared in English or Japanese need to be sent to us.
