Summary

The Board must issue a final decision in any instituted inter partes review on whether the challenged claims and any new claims under section 316(d) are patentable. After appeals end or appeal period expires, the Director must issue and publish a certificate cancelling unpatentable claims, confirming patentable claims, and adding new or amended claims to the patent. Those added claims have the same effect as reissued claims under section 252 for anyone who made, purchased, used, imported, or substantially prepared to do so in the U.S. before the certificate. The Office must publish how long reviews took.
