Title 35 › Part III— PATENTS AND PROTECTION OF PATENT RIGHTS › Chapter 32— POST-GRANT REVIEW › § 328
When a post-grant review goes forward and is not dismissed, the Patent Trial and Appeal Board must issue a final written decision about whether the claims the petitioner challenged and any new claim added under section 326(d) are patentable. After the appeal time ends or any appeal finishes, the Director must publish a certificate that cancels claims found unpatentable, confirms those found patentable, and adds any new or changed claims found patentable into the patent. Any new or changed claim added this way has the same legal effect described in section 252 for people who made, bought, used, or imported something covered by that claim, or prepared to do so, before the certificate was issued. The Patent Office must also publish data showing how long each post‑grant review took from start to final decision.
