Pursuant to the revised Patent Law that will be enforced from March 1, 2017, if an examiner finds a clear ground for rejection before patent registration, even after an applicant receives a Decision to Grant a Patent, he shall be able to revoke the decision of granting a patent and resume examination thereof by official authority.

However, in a case where a patent right is registered, it not possible to revoke the decision of the grant of a patent in order to maintain the stability of rights.  Additionally, the revised Utility Model Law that will be enforced from March 1, 2017 also includes the same revision.
