American Conference Institute (ACI) - PTAB Practice Briefing


Fish Principal and Post-Grant Practice Co-Chair Karl Renner will moderate a roundtable at the American Conference Institute (ACI) PTAB Practice Briefing virtual event on December 2.

About the Event:

As 2021 draws to a close, it’s clear that several major factors the full effect of which we may not fully grasp until sometime in the future are drastically impacting PTAB practice.

The Arthrex decision is perhaps the most iconoclastic of these developments, as it questioned the constitutionality of APJ appointments, thus leaving unresolved questions which may affect pending and future IPRs as well as previous IPR decisions. Arthrex also gives unprecedented discretionary authority to the PTO Director, who still at this time has yet to be appointed. There are also ongoing questions about discretionary denials and the future direction of IPRs. All proving that PTAB Practice is still a work in progress, and its related jurisprudence is still evolving. Attend ACI’s inaugural PTAB Briefing for in depth-discussions and year-end analysis of these most significant developments impacting PTAB practice as well as future forecasts for 2022. Panel details are below.
