Q156. Who can file a request for a trial for correction?

A156. The patentee (patent owner) can only file the request. Please note that, when a request for the trial is filed regarding the patent of the joint ownership, all of joint owners have to jointly file the request. Further, if there is a non-exclusive licensee under Art. 35(1), 77(4) or 78(1) of the Japanese patent law, an exclusive licensee, or a pledgee, the patent owner needs the consent of the said person in order to file the request.
