Q. Is it necessary to inform the Japan Patent Office (JPO) when a patent application (or a patent right) has been assigned from Company A to Company B? If yes, what is the procedure for doing that? Also, what document(s) is/are required?

A.

If an application is pending at the JPO, a Notification of Change of Applicant(s) must be submitted to the JPO. If a patent has been registered, a Request to Register Transfer of Patent Rights must be submitted to the JPO, along with a deed of assignment that proves that Company B (assignee) has succeeded to the application or patent rights from Company A (assignor).
Kyosei can process such an assignment on behalf of the concerned parties. If the application is pending at the JPO, Kyosei requires a POA form that is executed by the assignee. If a patent has been registered, Kyosei requires separate POA forms executed by the assignor and the assignee, respectively. Even if a patent has been registered, an assignee alone can submit a Request to Register Transfer of Patent Rights(s), as will be explained in the answer to the next question (No. 9), which follows. We will provide our cost estimate for such procedures on an ad hoc basis.
