| Overview of the Patent Process after Filing |
Formality Examination
Upon filing, the JPO assigns an application number and conducts a formality examination. If any formal deficiencies are found, the JPO will issue an “Invitation to Correct” (Order for Amendment), and the applicant must rectify the defects within a specified time limit. Publication of ApplicationA patent application is published in the Official Gazette after 18 months have passed from the earliest priority date. The applicant may also request early publication of the application. Substantive examination is initiated only upon the filing of a Request for Examination. Currently, the first office action is issued, on average, 10 months after the request is filed.
Voluntary Amendments
Substantive Examinations (Application Prosecution)
Applicants may voluntarily amend the claims, specification, and/or drawings at any time prior to receiving the first Office Action. For applications meeting certain requirements, expedited examination is available through systems such as Accelerated Examination, Super-Accelerated Examination, and the Patent Prosecution Highway (PPH). These programs significantly shorten the period until the first Office Action. Substantive examinations are conducted in accordance with the Examination Guidelines for Patent. The main requirements for patentability subject to examination are as follows.
Patentability Requirements
If the examiner finds reasons for refusal, a Notice of Reasons for Refusal (Office Action) will be sent to the applicant. If the applicant receives the notification, written argument and/or amendments must be submitted within the designated time limit (3 months for foreign applicants). This period can be extended by up to 3 additional months upon filing a request and paying the required fees. Final Decision Decision of Patent GrantIf the examination finds no reasons for refusal, or if the reasons for refusal were resolved by written argument and/or amendments, a Decision of Patent Grant will be made. In order to have the patent registered, the required registration fees (the first to third years) must be paid within 30 days from the date of receipt of the Allowance Notice from JPO. Certificate of Patent will be issued accordingly. If the reasons for refusal were not eliminated, a Decision of Rejection will be made.
1. Appeal against Decision of Rejection
An appeal against the decision of rejection may be filed within four months from the date of service of the certified copy of the decision of rejection. An amendment may be filed at the same time. This period is not extendable. A divisional application may be filed within four months from the date of service of the certified copy of the decision of rejection. The application may be converted into a utility model application or a design application. |
| Annuity Payment |
To maintain the patent right, the patent fee (annuity fee) must be paid every year. |

Patent, Trademark Application and Registration Information
| Necessary documents and information for filing |
|
| Not necessary for filing | Evidence of assignment from the inventor to the applicant prior to application is not required. |
| PCT Japanese National Phase filing requirements |
|
| Filing and the First-to-File rule | The application request, specification (with claims), abstract and drawings should be submitted in Japanese. Recently, the J.P.O. has begun accepting applications with the specification and claims written in English. However, the request for application must be written in Japanese. Additionally, the entire application must be translated into Japanese within 2 months of the application date. Japan applies a first-to-file rule. The first person to file an application for a patent in Japan will be given priority over all subsequent applicants. The search for prior art in Japan includes a search of both patent applications and registrations, and utility model applications and registrations. |
| Publication of the applications | 18 months from the application date, Japanese patent applications are published. This is referred to in Japanese law as “laying open the application.” |
| Patentability and Novelty | Under Section 29 of the Patent Act, inventions that were publicly known in Japan prior to filing shall not be granted patents (see See Section 29(i)). Similarly, inventions which were publicly used in Japan prior to filing, and inventions which were described in a publication distributed in Japan or elsewhere prior to filing will also not be granted patents (see See Sections 29(ii) and (iii)). |
| Examination | A request for substantial examination of an application should be filed within 3 years from the application date.(For PCT applications, the international application date is used.) If no request is filed, the application is regarded as withdrawn. If the examiner issues an office action, the applicant can respond by submitting an Argument and/or an Amendment to the J.P.O. During examination, any amendment must be within the scope of the original application or it will be refused. There are no maintenance fees for patent applications. After the application is allowed, the applicant must pay a patent annuity fee for the first 3 years of the patent. For the next 4 – 20 years, the patentee can pay the fee annually in a lump sum for the full period, or a portion thereof. |
| Patent term | A patent may remain in force for 20 years from the application date. However, for pharmaceutical patents, a maximum of a 5- year extension on the patent term is available under certain conditions. Please contact us if you have any questions about this specific issue. |
| Conversion | Patent applications may be converted to utility model applications or design applications. |
Procedures for Obtaining a Utility Model Right
