Patent origin is determined by the residence of the first-named inventor.
A reissue application is filed to correct an error in the patent, where, as a result of the error, the patent is deemed wholly or partly inoperative or invalid. An error in the patent arises out of an error in conduct which was made in the preparation and/or prosecution of the application which became the patent.
