This issue of The PTAB Review begins with a brief summary of changes to America Invents Act (AIA) trials recently proposed in Congress. It then explores a recent Federal Circuit decision rejecting arguments that the Patent Trial and Appeal Board (PTAB) is structurally biased in favor of institution. Next, it provides a cautionary discussion about evidence selection and rules. Finally, it provides an analysis about when a petitioner’s case can and cannot be buttressed after the petition is filed.
