It’s been a decade since the America Invents Act (AIA) transformed the U.S. patent landscape from a first-to-invent to a first-inventor-to-file system and added new contours with the creation of the Patent Trial and Appeal Board (PTAB) to hear post-grant patent challenges outside of court. While the AIA’s inter partes review process and other post-grant procedures have helped weed out weak patents, they’ve also increased the uncertainty and unpredictability of many patents. Now, 10 years on, Congress is assessing how the PTAB has developed in real life and considering what course corrections may be needed.
