Patent Act Article 31May 1, 2019

First-to-file principle

Where two or more patent applications are filed for the same invention, only the earliest application can be granted. The above shall not apply if the priority date claimed for the later-filed application is earlier than the filing date of the earlier application.

If the filing date and the priority date referred to in the preceding paragraph are the same, the applicants shall be notified to reach an agreement with respect to the matter concerned. If such an agreement cannot be reached, none of the applications shall be granted. If the said patent applications are filed by the same applicant, the applicant shall be notified to select one patent application within a specified time period; failure to make a selection within the time period shall result in the rejection of all such patent applications.

While the applicants concerned are in the process of reaching an agreement, the Specific Patent Agency shall require that these applicants report the results of the negotiation within an appropriate time period. If the said report is not provided within the specified time period, it shall be deemed that an agreement has not been reached.

Where a patent application for invention and a patent application for utility model are filed separately in respect of the same creation, the provisions set forth in the preceding three paragraphs shall apply mutatis mutandis, except for the circumstances stipulated in Article 32.

Patent Act Article 32May 1, 2019

One creation applied for invention patent and utility model patent

An applicant filing a patent application for invention and a patent application for utility model for the same creation on the same date shall make respective declarations in respect of the said applications. If the patent application for utility model has been granted before an approval decision on the patent application for invention is rendered, the Specific Patent Agency shall notify the applicant to make a selection within a specified time period. The patent application for invention shall not be granted if the applicant fails to make such declarations or selection within the specified time period.

Where the applicant selects the patent application for invention according to the provision set forth in the preceding paragraph, the utility model patent right shall become extinguished on the publication date of the invention patent.

The patent application for invention shall not be granted if the utility model patent right has become extinguished or has been revoked finally and bindingly before a decision is rendered on the patent application for invention.
