• A reissue may correct patent defects that might call the validity of the patent into question. It is also used, although rarely, to make the claims broader or narrower. The patentee risks the possibility that previously allowed claims may be rejected. It does not change the term of the patent. 35USCA § 251. — Sometimes shortened to reissue. [Cases: Patents 135. C.J.S. Patents § 239.]
