Patent Trial and Appeal Board
The United States Patent and Trademark Office (USPTO) Patent Trial and Appeal Board (PTAB) conducts the inter partes reviews, post-grant reviews, and the transitional post-grant reviews for the patent office. The PTAB also hears appeals from decisions of USPTO examiners. PTAB decisions are strong indicators of trends within the USPTO. Even if the decisions are not precedential, it is useful to read their decisions.
