Background
Upon completion of a PTO reexamination proceeding, the Commissioner will issue and publish a certificate canceling any claim of the patent finally determined to be patentable, confirming any claim of the patent determined to be patentable, and incorporating in the patent any amended or new claim determined to be patentable. These certificates are the same for normal or reissue patents
