  • Japanese National Phase Entry Request (prepared by us)

A Power of Attorney is NOT Required
6.What is a Substantive Examination?
A Substantive Examination is carried out by the JPO to decide whether a claimed invention should be patented or not. It will check whether the application fulfills the legal requirements and determine if there are any reasons for refusal.
7.When is a Substantive Examination carried out?
A Substantive Examination is only carried out by the JPO when requested by the applicant and involves an additional fee. If requested at the time of filing of the translation, we will waive the attorney fees.
8.How can I make sure the JPO will approve my patent?
The JPO will consider the following points:
  • Is it based on a technical idea that uses a law of nature?
  • Does the idea have any industrial application?
  • Did the idea exist before the current application was filed?
  • Could the invention have been easily developed by a person skilled in this field?
  • Was the applicant the first to file?
  • Will the invention contravene public order and morality?
  • Do the descriptions in the specification conform exactly to the requirements for patentability?
9.Can I appeal a refusal?
If the JPO determines after an examination that there are grounds for refusal, you will be notified.
You are entitled to submit either a written argument claiming that the invention differs from the prior art to which the Notification of Reasons for Refusal refers, or, alternatively, amend your patent to address the reasons for rejection.
9.If my patent application is successful
If no reasons for refusal are found, the JPO will grant the patent. When the patent fee has been paid, the invention will be added to the Patent Register and assigned a patent number. A certificate of patent will be sent to the applicant to acknowledge this formal registration.
The patent will be published in the Patent Gazette, which is an online resource for researching existing applications.
