Outline of Accelerated Examination and Accelerated Appeal Examination

The accelerated examination system/accelerated appeal examination system is a system enabling an examination to be conducted more quickly than under the regular examination upon the applicants' or appellants' request.

1. Advantages of requesting for accelerated examination/accelerated appeal examination

Compared to the regular examination system, examination results under accelerated system come out more quickly. The average FA pendency under the accelerated system is about 1.9 months (in 2012), which is much shorter than under the regular system.

Also, where an accelerated appeal examination is requested, an appeal decision is made and dispatched within 3.3 months (on average) from the date that accelerated appeal examination is requested and appeal proceeding becomes possible. (in 2012).

(*) The technical fields are shown with the International Patent Classification (partly with the File Index).

2. Applications/Appeals eligible for the accelerated examination system

Currently, the system can be applied to the following six types of applications and appeals against an examiners' decision of refusal for the applications:

  • i) Working-related applications;
  • ii) Internationally-filed applications;
  • iii) Applications filed by SMEs, individuals, universities, public research institutes etc.;
  • iv) Green-technology related applications;
  • v) Earthquake Disaster Recovery Support-related applications
  • vi) The Asian Business Location Law-related applications.


Patent applications falling under the categories below are eligible for the accelerated examination system or accelerated appeal examination system.

  • c) Applications that have been filed with the JPO as domestic applications and also filed with the Receiving Office under the PCT.

iii) "Applications filed by SMEs, individuals, universities, public research institutes etc."

Applicants of an invention, in whole or in part, are SMEs, individuals, universities or public research institutes, approved TLOs, or authorized TLOs.

iv) "Green-related applications"

This type covers such patent applications that intend to obtain a patent of “green invention (a kind of invention that has an energy-saving effect and contributes to CO2 reduction)”

v) "Earthquake Disaster Recovery Support-related applications"

This program can be applied to patent applications related with the aforementioned applications that fall under (a) or (b) as follows.

  • a) Applications by all or some of applicants who have an address or temporary residence in the specified affected areas (See Reference) and applications by people affected by the earthquake.
  • b) If the applicant is an incorporated entity, and the incorporated entity’s business establishment in the specified affected areas suffers damages from the earthquake and related disasters, and the applicant intends to file an application for an invention related with business operations of such business establishments as the invention that is created or licensed as business operations of such business establishment.

And a third party is unable to request for the accelerated (appeal) examination on another persons’ application or appeal.

4. Procedure for the accelerated examination and accelerated appeal examination

  • (i) A request for an accelerated (appeal) examination will be made by submitting a “Written explanation of the needs of the accelerated (appeal) examination”.
