Reissue is a procedure in the U.S. in which a patent owner seeks correction of an error in a patent. The error must be one that renders the patent partially or wholly inoperative or invalid, and the error must have occurred without deceptive intent. Typical reasons for seeking reissue are to broaden or narrow patent claims, or to correct typographical errors, the inventor listing, or other inadvertent procedural errors.
