This Year in Review synthesizes key events and decisions from 2023 into a digestible guide that we hope will serve as a helpful reference for those who practice before, or adjacent to, the PTAB. As in the past, many of our articles follow a data-driven approach in order to sift out trends and to identify best practices for parties on both sides of the “v.” As a firm that has handled over a thousand PTAB proceedings – second-most of any firm and including four inter partes reviews filed during the PTAB’s first week of operation - we apply our vast experience and data analytics to examine decisions and PTAB developments in order to provide practical insights to guide patent litigation strategy with a focus on the PTAB.
