Change of Applicant of a Pending Patent Application

Q1. What are the documents necessary for changing the applicant of a pending Japanese application?

A1.  For recordal of a new applicant at the Japan Patent Office, we need an Assignment from the original applicant (assignor) to assign a part or whole of the right to obtain patent to the new applicant (assignee).  Specifically, the following documents must be filed with the Japan Patent Office:

   (1) An executed assignment simply signed by both parties (the assignor and the assignee), in which the full names and titles of the representatives of the assignor and the assignee should be clearly indicated.

   (2) A power of attorney executed by the assignee.

Neither notarization nor legalization of documents (1) and (2) are required.  These documents may be prepared at our end and forwarded for execution by the assignor and the assignee.

Q2. Does the Japan Patent Office issue an official certificate for the recordal of a new applicant?

A2.  No certificate is issued by the Japan Patent Office.  Recordal of a new applicant can be confirmed by checking the patent database.

Addition of New Inventor to a Pending Patent Application

Q1. What are the statutory requirements for being named as an inventor in a Japanese application?

A1.  The statutory requirements for being named as an inventor in a Japanese application are the same as the US requirements.  Although an “inventor” is not clearly defined under the Japanese Patent Law, it is understood that an inventor is a person who actually participated in the creation of an invention, and either a mere assistant, an advisor, a person who provided financial support or a person who only gave instructions is not an inventor.

Q2. What are the documents necessary for adding an inventor to a pending Japanese application?

A2.  For adding a new inventor to a patent application, we need to file a Statement executed by the applicant and all inventors (Neither notarization nor legalization of the Statement is required). 

Such a Statement can be prepared at our end and forwarded for execution by the applicant and the inventors.
