The PTAB: inter partes review, post-grant review and appeals
The Patent Trial and Appeal Board hears appeals from examiners’ rejections and conducts the trials the America Invents Act created: inter partes review and post-grant review. Whether a petition is instituted, and whether the Director reviews a decision, now shapes much of patent litigation.
Follow the Board’s precedential decisions, Director Review and guidance below, and see institution rates on our dashboard.
