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.
