Addition of Inventor and Assignment Recordal

How to record assignment of a Japanese patent application and addition of inventor before the Japan Patent Office?

1) Addition of Inventor:

Please note that it is only before the registration of a patent that the addition of an inventor can be made.

We will provide you with a Declaration form to formally record the inventorship of an application in Japan.  Please have the form duly executed by all of the inventors and return the ORIGINAL to us.

2) Government Fee for Assignment Recordal:

Please note that the government fee for an Assignment recordal will increase from JPY 4,200 to JPY 15,000 once the first three annuities are paid.  Therefore, we ask our clients to execute the Assignment form and the Power of Attorney and return them to us well before the due date of the payment of the first three annuities when recording the Assignment.

3) Assignment Form:

In order to record assignment of an application in Japan (from A to B), it is necessary to file an Original Assignment with the JPO.  If it is impossible to have the original Assignment, we will prepare a new simple Assignment Form to be executed by a representative of A and a General Power of Attorney Form to be executed by B.  Please have these forms duly executed and return the Original copies to us.
