Dispute Summary
Guntert & Zimmerman seeks Director Review to overturn the PTAB’s institution of a post‑grant review of claims 1‑7 of U.S. Patent 11,772,723, arguing the patent is pre‑AIA and that collateral estoppel bars the petitioner’s arguments. The request centers on three legal questions about estoppel, preclusive effect, and amendment‑induced AIA status.
